Engineering and High Performance Plastics Market Report
1 Introduction 1.1 Background Engineering polymers have been commercially available for many decades and a number of new high performance materials have also been introduced onto the marketplace during the last twenty years or so. Polymer scientists continue to develop higher performance thermoplastics that can challenge traditional materials such as metal and thermosets. Indeed, the last five years have seen substantial growth in top of the range materials such as liquid crystal polymers and polyketones. There is no widely accepted industry definition of an engineering or high performance polymer. However, these materials typically possess a range of desirable performance properties such as strength, temperature resistance and dimensional stability that are far superior to standard thermoplastics. There is inevitably an overlap between high-end engineering plastics and the lowend performance materials in terms of their property profile. As a general rule of thumb however, high performance plastics are considered to have a short-term heat resistance of 250 °C and longterm heat resistance of 160 °C. Engineering and high performance polymers have shown considerable growth during the latter half of the 1990s. Demand was fuelled primarily by product development, material substitution and strong growth in key market sectors such IT/telecom and automotive. The worldwide downturn in economic activity after 2000 has however meant a sharp reduction in demand for engineering thermoplastics. It was therefore felt timely to examine the world market for performance plastics to determine how suppliers are responding to lower consumption and to consider future growth prospects for the industry. A number of other interesting developments are also taking place that will have an important impact on future market trends. In the automotive sector for example, the European Union (EU) has introduced a Directive on material recycling of end-of-life vehicles, which will have significant implications for material selection. The EU has also introduced a Directive concerning Electrical & Electronics (E&E) waste, which will have similar implications for manufacturers of electrical goods. Standards and regulations concerning many aspects of the key automotive and E&E sectors are also being tightened. The pace of product and applications development has been unrelenting in recent years. New and improved grades continue to be introduced to meet more demanding specifications. Suppliers are also working ever more closely with converters and original equipment manufacturers (OEM) to develop new and innovative technologies and applications. The global structure of the industry is also changing. A growing share of engineering polymer production is now taking place in China and other Pacific Rim countries as OEMs relocate their manufacturing plants to lower cost economies. At the same time, North America, Japan and Western Europe are becoming more mature and lower growth markets. 1.2 The Report The report starts with an overview of the whole spectrum of engineering and high performance polymers, including their chemical structure, properties, processing and an outline of key applications. Chapter 4 examines the global market for each polymer type, showing consumption by major world region and market sector for the period 1999-2002, and forecasts for 2007.

Engineering and High Performance Plastics Market Report
2 Executive Summary 2.1 Global Market Forecasts In 2002, total world consumption of engineering and high performance plastics is estimated at 10.9 million tonnes, which represents approximately 7% of total world plastics consumption. Demand for engineering and high performance plastics has outperformed the plastics sector as a whole in recent years. During the period 1995-2000, the average growth in consumption of engineering and high performance plastics was between 8-10% per annum compared to 5-6% per annum for standard thermoplastics. The principal drivers of demand for engineering and high performance thermoplastics are: • • • •
Replacement of traditional materials such as metal and thermosets because of their lighter weight, ease of processing, design flexibility and lower total cost. Development of new applications. Product improvement and development. High growth in key end user markets such as electronics, telecommunications and automotive.
The downturn in world economic activity and the collapse of the IT/telecom sectors led to a reduction in demand for engineering and high performance plastics in 2001. World consumption fell by 6% from just over 11.0 million tonnes in 2000 to 10.4 million tonnes in 2001. Last year, world demand increased by an estimated 4.5%, but still remains below the level of 2000. Table 2.1 shows growth forecasts for engineering and high performance polymers for 2007. Table 2.1 World consumption of engineering and high performance plastics, 2000, 2002 and forecast for 2007, (000 tonnes) Compound annual growth 2000 2002 2007 rate (CAGR) 2002-2007 (%) Polyamide 2,002 1,950 2,430 4.5 ABS 4,736 4,667 5,280 2.5 PBT 484 477 623 5.5 POM 609 604 717 3.5 PMMA 986 989 1,174 3.5 Polycarbonate 1,726 1,714 2,637 9.0 PPS 53 50 77 9.0 Polyetherimide 15 15 24 10.5 PPO/PPE 368 353 461 5.5 PSU/PES 23 23 37 10.5 LCP 18 18 34 13.5 PEEK 1.4 1.3 2.4 13.5 TOTAL 11,022 10,860 13,497 4.5
The growth forecasts for all polymer types over the next five years are much more pessimistic than would have been envisaged only two years ago. In 2007, world consumption of engineering and high performance plastic is projected at 13.5 million tonnes. This represents a compound annual growth rate of 4.5% for the period 2002-2007. The main reasons for downgrading polymer growth projections are:

Engineering and High Performance Plastics Market Report
•
The sharp downturn in world economic activity that has occurred since 2001, and the uncertain prospects for any substantial recovery in demand for at least another couple of years.
•
Lower growth expectations from key market sectors such as IT, telecommunications and automotive.
•
Major application areas for engineering plastics in particular, are maturing, which will restrict opportunities for further material substitution.
High performance plastics such as PEEK, LCP and the sulfone based polymers, will grow at double-digit rates during the period 2002-2007, as the potential for applications development and material substitution is much greater for these developing polymers. In contrast, the more mature engineering plastics such as polyamide, ABS, polyacetal and acrylics, will show the lowest rates of growth during the next five years. 2.2 Material Trends Product improvement and new product development are important features of the market. Polymer suppliers are continuously seeking to enhance the performance properties of their products to meet ever more demanding regulatory and customer requirements. A number of new high performance materials have also recently been developed. These include cyclic olefin copolymers (COC), syndiotactic polystyrene, cyclic butylene terephthalate (CBT) and copolycarbonate. The most important product development trends include improvements to the following properties: • • • • • • • • • • • • •
‘Easy-flow’ grades with reduced cycle times particularly aimed at thin wall electrical parts. Halogen-free flame retardant materials. High heat grades for electrical and automotive under-the-bonnet applications. High toughness grades for E&E applications. Improved static dissipating properties. Higher conductivity products, which make parts painting easier in automotive applications. Fibre-reinforced and mineral-filled grades. Low odour emission grades Ceramic-filled grades of polyetherimide for E&E applications. Hydrolysis-resistant grades of PBT specifically for connectors used in automotive production. UV-stabilised POM for automotive applications. ‘Odour-free’ polyacetals for car interior applications. PPS grades that resist aggressive media such as gasoline, diesel or liquefied natural gas.
Another important product trend is interpolymer substitution. In the automotive sector, engineering polymers such as polyamide and ABS for example, are being challenged by reinforced polypropylene in a number of application areas. PBT has also been replacing polyamide in some car electrical applications because of its better dimensional stability. PPO/PPE blends have replaced other polymers in bumper systems because of their better heat resistance and conductivity. Also, given the increasing temperature requirements under-the-bonnet, higher performance plastics such as PPS have been replacing plastics such as polyamide. In the electrical & electronics sector, higher cost and high performance materials such as PES/PSU and polyetherimide are subject to growing competition from other less expensive amorphous high temperature plastics due to rising cost pressures. At the same time, because of rising performance requirements, LCP and PPS are taking share from less expensive materials such as polyamide.

Finally, consumers are demanding products that reflect their individuality and new styles in terms of design and colour are emerging much more quickly. In response to these trends plastics producers such as Dow and GE Plastics, have introduced lines of special effect resins. These can be used to create coloured moulded parts at a lower cost with special effects such as metallic, glitter, fluorescent, marble and pastel. 2.3 Regional Trends Table 2.2 shows percentage share of engineering and high performance polymer consumption by world region for 1999 and 2002. Table 2.2 Percentage share of engineering and high performance plastic consumption by world region 1999 2002 Western Europe 23.1% 23.5% North America 35.6% 33.3% Japan 11.1% 10.5% Rest of Asia Pacific 28.5% 31.0% Rest of World 1.7% 1.8%
North America remains the largest market for engineering and high performance polymers, followed by ‘Rest of Asia Pacific’ and Western Europe. The ‘Rest of Asia Pacific’ region excludes Japan, and is increasing its share of consumption faster than any other world region. Between 1999 and 2002, China and other Pacific Rim countries, raised their share of total consumption from 28.5% to 31.0%. This is due mainly to the growing trend for automotive and electrical and electronics companies to shift manufacturing facilities to lower cost economies. During the same period the shares of both Japan and North America declined. This is largely explained by the economic downturn and growing market maturity for many key applications, as well as the relocation of production by end users. The share of Western Europe increased slightly during the last three years to reach 23.5% in 2002. Other world regions such as Latin America account for a very small percentage of total world consumption, although their market share is growing slightly. 2.4 Technology Tends A number of new processing technologies are being developed to bolster growth in use of engineering and high performance polymers, particularly for automotive applications. These include: • • • • • • •
Fusible core technology, which has made rapid progress, with major investment by leading moulders throughout Europe. Friction welding of separately moulded individual components and blow moulding of high molecular weight natural and glass-reinforced polymers are also opening up new opportunities. Blow moulding developments, also includes process variants such as suction blow moulding. ‘Hybrid technology’, that binds plastics and steel to reduce weight and lowers module costs to create a high load-bearing capacity while allowing high energy absorption. ‘In-mould painting systems which can reduce capital costs and avoids the component handling necessary prior to painting. ‘Outsert’ technology’ (metal-plastic composites) offers good growth potential for engineering polymers in automotive applications. Combination of engineering polymers with injection moulded ‘soft’ components, including NBR rubber and polyester elastomers. 5

2.5 Market Trends Table 2.3 shows the percentage share of world engineering and high performance plastic consumption by market sector for 1999 and 2002. Table 2.3 Percentage share of engineering and high performance plastic consumption by market sector, 1999-2002 1999 2002 Automotive 26.4% 26.3% Electrical & Electronics 23.9% 23.4% Consumer products 18.4% 19.8% Industrial 15.7% 15.1% Other 15.6% 15.5%
The automotive sector is the largest consumer of engineering and high performance polymers followed by electrical & electronics. The E&E sector was the principal driver of market demand during the second half of the 1990s. However, the slowdown in the electronics and telecom sectors resulted in lower demand for engineering plastics, and hence a declining share of the total market since 1999. The market share of automotive has declined only slightly during the last three years. Growth in automotive plastics was bolstered by continued substitution of traditional materials, despite the sharp downturn in automotive production. The share of the industrial sector has also declined because of lower investment and a decline in the construction industry. The fastest growing sector has been consumer products with an increase in share from 18.4% to 19.8% between 1999 and 2002. The main reason for the better performance of consumer products has been the greater resilience of consumer spending in the face of an economic downturn. The medical devices market also presents some interesting growth opportunities for plastic. 2.6 Competitive Tends There are over fifty producers of engineering and high performance plastics worldwide in 2002. The world’s largest suppliers are global and multi-product companies with production facilities in all three major world regions. In terms of production capacity, the leading suppliers are GE Plastics, Bayer, BASF and DuPont. Several other companies also offer a broad range of engineering and high performance plastics. These include Dow, Ticona and Solvay Advanced Polymers, which specialises in high performance materials. Several Asian companies are developing their engineering plastics businesses through investment and joint ventures. The most broadly based operations in terms of product range include LG Chem of South Korea, Mitsubishi (Japan), Asahi Kasei (Japan), Sumitomo (Japan), Teijin and Toray, both of Japan. Engineering and high performance plastics markets are characterised by a high degree of concentration. The top three world suppliers of polycarbonate (GE Plastics, Bayer and Teijin), for example, control around 70% of total supply. The three leading polyamide suppliers control 55% of world supply and the largest three ABS producers account for 57% of world production. The most extreme cases are polyetherimide, polyphthalamide and PSU, where there are only one or two world suppliers of each type of plastic. The most notable competitive trends in engineering and high performance plastic markets are: 6
Engineering and High Performance Plastics Market Report
•
China and other Pacific Rim countries have been increasing their share of world polymer production since 1999, largely at the expense of North America and Japan. A growing proportion of the new capacity building that has taken place in the last three years has been in the Far East. At the same time, several engineering polymer producers have closed plants in the USA and Europe due to over-capacity and negative returns. Asia’s share of world engineering polymer production is expected to grow much further in the coming years.
•
A number of major western engineering plastic suppliers have established joint venture businesses with local suppliers in the Far East to capitalise on the growth opportunities.
•
Globalisation in key end user markets such as automotive, electrical & electronics and domestic appliances, are encouraging the process of market concentration and globalisation in engineering plastic supply. The trend toward globalisation in end user markets means that customers are becoming more powerful and demanding of their suppliers.
•
Customers are also demanding more customised grades to differentiate themselves in the marketplace. Engineering polymer producers are responding to this growing trend by working more closely with key customers and developing new grades, colours and special effect polymers with one customer in mind.
•
Some engineering polymer producers are even moving further downstream by offering customers greater access to their knowledge and technology to create higher value services.
•
Merger and acquisition activity between engineering polymer suppliers has slowed considerably since the period 1999-2000, when a large number of deals took place. This is due mainly to lower returns and uncertain demand trends facing suppliers.
•
New entrants have been attracted into the fastest growing sectors such as LCP and PEEK, during the last two years.
•
Engineering polymer prices, while being less volatile than standard thermoplastics, have experienced a long-term decline due to growing competition and the ‘experience curve’ effects of rising volumes (the decline in unit costs as cumulative volumes increase). This partly explains why most producers are currently facing either low or negative returns on their investment.

3 Overview of Engineering and High Performance Plastics 3.1 Introduction This section presents an overview of the main types of engineering and high performance thermoplastics, their key properties and applications. A more detailed analysis of applications and market trends are presented in subsequent chapters. Engineering polymers include polyamide (PA), polybutylene terephthalate (PBT), acrylonitrilebutadiene-styrene (ABS), polyacetal (POM), polymethyl methacrylate (PMMA) and polycarbonate (PC). These materials have significantly better mechanical properties than standard commodity thermoplastics including high heat resistance, dimensional stability, strength and resistance to a range of chemicals. These properties have enabled engineering plastics to replace traditional materials such as metal and thermosets in many demanding applications areas such as automotive, electrical & electronics, consumer products, industrial machinery and medical markets. It is difficult to agree on a precise definition of a high performance plastic. There is indeed a clear overlap across the entire classification spectrum of thermoplastic materials. Some commodity plastics can be modified through reinforcements to compete with traditional engineering resins. Glass fibre-reinforced polypropylene is a good example of a standard thermoplastic material that is challenging polyamide and ABS in many different fields of application. As a general rule of thumb, high performance plastics are considered to have a short-term heat resistance of 250 °C and can withstand long-term heat resistance of 160 °C. Other distinguishing features of high performance plastics include their high strength and stiffness, resistance to many chemicals and their outstanding electrical properties. Table 3.1 shows continuous use temperatures for engineering and high performance polymers. For comparative purposes, 30% glass fibre-reinforced grades have been selected. PEEK has the highest continuous use temperature of up to 260 ºC, followed closely by liquid crystal polymers. Other high performance polymers are polyphthalamide (PPA), polyamideimide (PAI), polyarylimide, polyphenylene sulfone (PPSU), polyphenylene sulfide (PPS), polyetherimide (PEI), polysulfone (PSU), polyethersulfone (PES).

Engineering and High Performance Plastics Market Report
PBT has the highest continuous use temperature of the engineering polymers, followed by polycarbonate, POM, polyamide, ABS and acrylics. PPO/PPE alloys are often considered to be high performance materials due to their excellent combination of properties such as high impact strength and dimensional stability, although their continuous use temperature is lower than some engineering plastics. There are also a number of high performance materials that are relatively new to the market including: cyclic olefin copolymers (COC), syndiotactic polystyrene, cyclic butylene terephthalate (CBT) and copolycarbonate. These developing materials are described in Section 3.18. Engineering and high performance plastics can also be classified according to whether the polymers are semi-crystalline or amorphous. A crystalline polymer denotes a molecular structure in some resins, which denotes uniformity and compactness of the molecular chains forming the polymer. Normally this can be attributed to the formation of solid crystals having a definite geometric form. An amorphous polymer is devoid of crystallinity, with no definite order. Semi-crystalline thermoplastics are noted for very good electrical properties, as well as the ability to withstand both high heat and severe chemical environments. They include polyamide, PBT, polyphenylene sulfide (PPS), polyphthalamide, polyarylimide, liquid crystal polymers and polyketones. Amorphous materials are random entanglements of polymer chains, known for very good mechanical properties (strength, stiffness) and dimensional performance. Amorphous polymers include ABS, polycarbonate, PPO/PPE, polyphenylene sulfone, polyethersulfone, polysulfone and polyetherimide. Nowadays, there are many different types of engineering and high performance plastics to choose from. In contrast, back in 1980, the plastics design engineer had a much smaller number of materials from which to choose. Among the thermoplastics there were the fluoropolymers that were ideal for extrusion applications such as wire and cable insulation. These resins were not however easily adapted to produce complex injection moulded parts. There were also the sulfone-based resins such as polysulfone and polyphenylene sulfone, and polyamideimide, which had proven itself in small parts that had to operate in hostile environments. Among the thermosets, there were only a few commercial grades of bismaleimide on the market, requiring heavy glass or carbon fibre reinforcement to overcome this resin’s inherent brittleness. During the 1980s and 1990s, the pace of research and commercialisation of high-temperature plastics accelerated dramatically. The thermoplastic resin manufacturers introduced many new materials based on imide, sulfone, and ketone-based polymers. These include polyetherimide (1982) and polyphthalamide (1991). Polyketones and liquid crystal polymers were also commercialised in the 1990s. Competing materials at the high performance end of the market such as thermosets have also seen significant product development in recent decades. The thermoset manufacturers have brought out a whole range of polyimides with excellent mechanical performance at elevated (250-350 °C) temperature for use in applications including automotive, military and commercial aircraft engines. The thermal and mechanical performance of all the major thermosets such as epoxy, phenolics, vinyl ester and cyanate esters, have also been enhanced through compounding with hightemperature thermoplastics and modifying the basic thermoset formulations. In effect, the search for higher-temperature performance extends right through the whole contemporary resin classification system, and this is leading to increased competition among the suppliers and increased options among the end-users. Manufacturers of commodity resins such as
10
Engineering and High Performance Plastics Market Report
polystyrene, polyamide and PVC have recently introduced ‘high-temperature’ grades of their resins. Formerly intractable resins such as polyphenylene oxide and maleic anhydride have been harnessed to high-temperature applications through the medium of alloying and blending with more processable resins. Alloying and blending has also been a route to synergistic combinations of thermal and mechanical performance in the field of polyimides and liquid crystal polymers. 3.2 Polyamide (PA)
3.2.1 Properties Polyamide or nylon is a semi-crystalline polymer and has been commercialised since the mid 1930s. This material offers an excellent combination of mechanical and electrical properties coupled with good resistance to heat and chemicals. It has high lubricity and moderate strength. It is tough, inexpensive, but has poor dimensional stability due to water absorption. A number of different types of polyamide are available covering a wide range of properties. The standard grades are PA6 and PA66. PA6 is made by hydrolytic polymerisation of caprolactam. PA66 is made by the polycondensation of hexamethylenediamine and adipic acid. Special copolyamide grades such as PA6/12 and PA6/66, partially aromatic grades and transparent grades are also produced. Polyamide 11 and polyamide 12 are high performance materials. Polyamide 11 is produced by polymerisation of amino-undecanoic acid from castor oil. PA12 is obtained from crude oil by polycondensation of lauryllactam. Polyamide is formed by two methods. Dual numbers arise from the first, a condensation reaction between diamines and dibasic acids produces a polyamide salt. The first number of the polyamide type refers to the number of carbon atoms in the diamine, the second number is the quantity in the acid (e.g., polyamide 612 or polyamide 66). The second process involves opening up a monomer containing both amine and acid groups known as a lactam ring. The polyamide identity is based on the number of atoms in the lactam monomer (e.g., polyamide 6 or polyamide 12, etc.). The key performance properties of polyamides are summarized below.

The main advantage of polyamide 6 over 66 is that it is easier to process and produces lower mould shrinkage. The main disadvantage of polyamide 6 is that it has lower strength, stiffness and abrasion resistance than polyamide 66 and higher water absorption. The main advantages of polyamide 66 are its better low temperature toughness than acetal, PBT and polyamide 6, and its good fatigue resistance. It should however be noted that the choice between polyamide 6 and 66 is often made for reasons of availability, price or familiarity, rather than for technical reasons. The exception to this is ease of moulding, where polyamide 6 dominates. Properties of partially aromatic, transparent polyamides are: • • • • • • • •
Transparent in all thicknesses High-gloss or textured, depending on mould surface Mechanical and electrical properties largely unaffected by moisture Tensile modulus: 3,000 MPa Short-term heat resistance to 120 °C Good dimensional stability Good electrical insulating properties Good resistance to stress cracking and chemicals, although not as good as PA 6 and PA 66

The main advantages of PA11 are its lower water absorption and UV resistance compared to other polyamides. It also has higher strength and heat resistance than PA12. It is however more expensive than PA6 and PA66. PA12 is tougher than PA11 and has lower water absorption than standard polyamides. PA12 is however expensive and has the lowest strength and heat resistance of any unmodified polyamide. PA612 offers higher stiffness, hardness and thermal stability compared to PA12. It also has lower water absorption than PA6 and PA66. The main disadvantage is that it has a lower heat distortion temperature than PA66 and is more expensive.
3.2.2 Applications Polyamide resins and compounds are used in a wide range of applications, which reflects the very broad range of grades currently available. Products are sold either as unreinforced resin or in compound form with mineral or glass fibre reinforcements. The automotive sector is the biggest market for polyamide. Main applications are under-the-bonnet applications such as the air intake manifold, the air and cooling systems, peripherals, throttle body housing, the cylinder head cover, the water-glycol circuit and engine parts. High performance PA is also used to make tubing for under-the-bonnet applications such as fuel systems. In car electrical systems, polyamide is found in the peripherals, sensors, switches, relays and electronic housing. For exterior parts, PA is used to manufacture parts such as rear mirror housing, door handles and windscreen wiper parts. In car interiors, applications include door handles, key lock systems, push buttons and switch control panels. Electrical & electronics is the next most important market for polyamide. It is used to manufacture electrical components such as switches, connectors, contactors and various household appliance components. It is also used for wire and cable jacketing. PA compounds often include flame retardant grades. Film is the third largest market followed by consumer products. Key applications include parts for appliances and power tools, caster wheels for furniture, sports equipment such as ski and snowboard bindings and packaging parts such as lighters and aerosol valves. Industrial applications are also significant users of polyamide. Polyamide is used for manufacture of many different components for industrial machinery and equipment. Applications include bearing cages, pumps, pneumatic connectors and cable chains. PA is also used for fixation products such as fasteners, staples and drills. Other markets include sheet, rod and tubes, filaments, and various other injection moulding applications.

3.2.4 Pricing Trends In December 2002, unreinforced grades of PA6 cost between €2,100-2,350 per tonne. Reinforced grades cost around €200 more. PA66 is more expensive than PA6, costing between €2,600-2,850 per tonne for unreinforced and €200 per tonne more for glass reinforced grades. Over the long term, the trend in polyamide prices is firmly downwards. In the early 1990s for example, PA6 prices reached €3,700 per tonne. Since then PA prices have moved in a cyclical manner, but the overall trend in prices is lower. 3.3 Polybutylene Terephthalate (PBT)
3.3.1 Properties Polybutylene terephthalate (PBT) is a semi-crystalline saturated polyester, which has been produced since 1942. PBT is made by the polycondensation of terephthalic acid or dimethyl terephthalate with 1,4-butanediol in the presence of a catalyst. Terephthalic acid, dimethyl terephthalate and 1,4-butanediol are derived from petrochemicals such as xylene and acetylene. The polymer is noted for high stiffness and strength, high resistance to heat, low water absorption and high dimensional stability. It has moderate chemical resistance and low resistance to strong acids and bases. There are a number of different grades and types of PBT resins and compounds available. The most widely used are unreinforced and reinforced injection moulding grades, followed by extrusion and coating grades. Injection moulding grades are available in a wide range of strengths and degrees of toughness. Reinforced PBT compounds contain glass or mineral filled reinforcements for added toughness, UV stabilisers or flame retardants for high heat electrical applications. PBT is also blended with polycarbonate to give special low warpage grades with high impact strength even at low temperatures. The volume of PC/PBT blends is included in the market definition of PBT. Table 3.3 presents a comparison of the performance properties of unfilled, 30% glass fibrereinforced and 30% long glass fibre-reinforced PBT grades. The main features of PBT performance properties are: • • • • • • • •

3.3.2 Applications Automotive is the largest market for PBT. Electronic components and housings are the main applications area for PBT in the automotive sector. Exterior applications are the next most important market with main uses being bumper fascias, mudguards, door handles, mirror housings and wiper arms. Interior applications include parts of the instrument panels such as ashtrays and interior trim. Electrical and electronics is the next largest market for PBT with principal applications including connectors, smart network interface devices (SNIDs), power plugs and electrical components, switches and controls, circuit breaker enclosures and outdoor telecommunications enclosures. PBT can also be found in electrical appliance components requiring high surface gloss and fibre optic tubing. Other applications include industrial, consumer and recreation products.
3.3.3 Pricing Trends PBT prices have fallen since the early 1990s. From a peak of just less than €4,000 per tonne, the long-term trend in PBT prices is downwards. In December 2002, PBT unreinforced cost around €2,850-3,300 per tonne with reinforced grades costing around €200 per tonne more. 3.4 Acrylonitrile-Butadiene-Styrene (ABS)
3.4.1 Properties Acrylonitrile-butadiene-styrene (ABS), an amorphous polymer, has been in mass production since the 1960s. It is a styrenic copolymer blend made out of elastomeric components and an amorphous thermoplastic component. The elastomeric component is usually polybutadiene or a butadiene copolymer. The thermoplastic component is SAN, a copolymer of styrene and acrylonitrile. SAN 15
Engineering and High Performance Plastics Market Report
can be either grafted to and/or blended with the elastomeric component. The three monomers (A, B and S) offer flexibility in tailoring the property profiles. Acrylonitrile provides chemical resistance, ageing resistance, hardness, rigidity, gloss and melt strength. Butadiene provides low temperature ductility, flexibility and melt strength. Styrene provides processing ease, gloss and hardness. Producers can vary the relative amount of the three components to optimise certain properties to meet the different requirements for various applications. The versatility of ABS can be further enhanced by substituting styrene with alpha-methylstyrene, or other high heat co-monomers, to obtain higher heat resistance. Probably the most notable property of ABS is its toughness and high impact strength at extreme temperatures which permit applications at temperatures of between –40 °C to +100 °C. ABS also offers good electrical insulation, low water absorption and good resistance to most chemicals. As far as processing is concerned, ABS has a good melt-flow, low shrinkage and produces excellent surface finish. The main disadvantages of ABS are its poor solvent and fatigue resistance, poor UV resistance, unless protected, and maximum continuous use temperature is only around 70 °C. ABS compounds are available in many forms including medium and high impact grades, high gloss, UV stabilized, flame retardant, heat resistant, low gloss, glass-fibre reinforced and transparent. Table 3.4 presents a comparison of the performance properties of medium impact, high impact and 30% glass fibre-reinforced ABS.

3.4.2 Applications Impact ABS is used for helmets, pipes and fittings, and housings for items such as vacuum cleaners, telephone sets and cameras. High gloss grades are used for domestic appliances such as
16
Engineering and High Performance Plastics Market Report
washing machines and refrigerator housings. Low gloss grades are used in automotive interior and domestic appliance housings. Flame retardant grades are used in electrical appliances such as TV, VCR, PC and printer housings. Heat resistant products tend to be used mostly in automotive applications. Transparent ABS is used to make clear parts for home appliances and business equipment. Automotive is the most important market for ABS. Main applications include loudspeaker grilles, door handles, door trim, instrument panels and consoles. ABS is also used for exterior components, electrical parts such as navigation systems housing and a small amount is used under-the-bonnet. PC/ABS blends are used for interior and exterior applications. ABS is widely used for manufacture of housings for a wide range of consumer products. These include cameras, business equipment, TVs, vacuum cleaners, food mixers, telephone sets and audio equipment, and many more. Electrical and electronics applications include transformer housings and switches. Other applications for ABS include pipes, sports equipment, safety helmets, luggage, furniture, medical equipment, tubes and caps.
3.4.3 Pricing Trends ABS prices have drifted downwards since the early 1990s. In late 1991, ABS cost around €2,250 per tonne. Since then, prices have moved in a cyclical fashion but the long-term trend is lower. In December 2002, natural grade ABS cost €1,350-1,550 per tonne. Coloured grades cost €1,7502,100 per tonne, with UV stabilized grades around €100 per tonne more. 3.5 Polycarbonate (PC)
3.5.1 Properties Polycarbonate is an amorphous engineering thermoplastic, which was first commercialised in 1958. Polycarbonate has excellent strength and toughness. It possesses good dimensional stability, dielectric strength, flame retardancy, and impact resistance (highest among transparent rigid materials). It is susceptible to stress cracking with aromatic solvents, and is difficult to machine. The introduction of glass fibres raises its heat deflection temperature but its impact strength is reduced in contrast to most other glass filled plastics. Common to all polycarbonates is the carbonate group in the main chain. Polycarbonates are referred to as aliphatic or aromatic, depending on the dihydroxy used in their synthesis. Aliphatic polycarbonates are of much less economic importance than aromatic types. Common pathways to aliphatic polycarbonate are the transesterification of diols with dialkyl or diphenyl carbonates or dioxolanones, in the presence of a catalyst. Aromatic polycarbonates are prepared from various bisphenols, the most widely used being bisphenol A. The synthesis of aromatic polycarbonates is based on the reaction of bisphenol with carbonic acid derivatives such as phosgene, diphosgene, carbonic acid esters and chloroformic acid esters. The most important process for production of aromatic polycarbonate is the so-called ‘interfacial process’, first developed by Bayer. In this process, bisphenol A is phosgenated in the presence of methylene chloride in controlled conditions. Advances in melt processing technology are challenging traditional ways of producing polycarbonate. The growing use of these non-phosgene processes is being prompted by lower capital costs and the fact that these are more environmentally friendly processes. Melt processing also gives better product quality for the fast growing optical media applications.

3.6 Polyoxymethylene (POM)
3.6.1 Properties Polyoxymethylene or polyacetal is a highly crystalline polymer. POM is most noted for its high stiffness, mechanical strength, abrasion resistance and good resistance to chemicals and solvents. It also displays good low temperature impact resistance, high dimensional stability, favourable frictional properties and low water absorption. The main disadvantages of the polymer are its poor resistance to acids and alkalis, and that it burns easily. It also has a restricted processing temperature range and poor UV resistance. Table 3.6 presents a comparison of the performance properties of polyacetal homopolymers, copolymers and 25% glass fibre-reinforced copolymers.

The first polyacetal was introduced in 1960. A problem which beset the moulders of the early polyacetal resins was that the polymer chains have to be stabilised to prevent the resin breaking down during processing at elevated temperatures. More heat-stable versions appeared in the early 1990s, incorporating new stabiliser technology that reduces mould and screw deposits. There are two different methods for producing polyacetals. Anionic polymerisation of formaldehyde produces homopolymers that crystallize particularly well and therefore have high stiffness and strength. The other method is cationic polymerisation of trioxane. Here the addition of small amounts of comonomers lowers the crystallinity to increase toughness. The stiffness and strength are however somewhat lower than for homopolymers. Copolymers are by far the most widely used polyacetals with a share of around 75% of total POM sales. Copolymers have been growing faster than homopolymers in recent years mainly because
19
Engineering and High Performance Plastics Market Report
they are easier to process. Homopolymers, on the other hand, have better physical and mechanical properties than copolymers.
3.6.2 Applications There are distinct markets for both types of polymer. Homopolymers are best suited to applications in which good abrasion resistance and a low coefficient of friction is needed. Applications include bearings, gears, conveyer belt links and safety systems like seat belts. Copolymers are best suited to applications that require low coefficient of friction such as electric kettles and water jugs, components with snap fits, chemical pumps, bathroom scales, telephone keypads and housing for domestic appliances. Polyacetals can be extruded, injection moulded and blow moulded. Most of the material is injection moulded. Injection moulding grades come in various melt viscosities and can be processed rapidly and easily into moulded parts. There are also impact modified injection moulding grades for high toughness applications and glass fibre-reinforced grades.
3.6.3 Pricing Trends In common with other engineering plastics, POM prices have been moving downward since the early 1990s. At the end of 1991, natural grade POM cost just over €3,500 per tonne. Prices have since fluctuated in response to changes in industry supply and demand, but the overall trend is lower. In December 2002, natural POM prices were between €2,150-2,500 per tonne. Glass reinforced grades cost up to €300 per tonne more. 3.7 Polymethylmethacrylate (PMMA)
3.7.1 Properties Acrylics are derived from esters and are produced by polymerisation of methyl methacrylates (MMA) to give a range of properties from soft elastomers to stiff thermoplastics. The main features of polymethylmethacrylate (PMMA), or acrylics, are their excellent clarity and UV resistance, good abrasion resistance, stiffness and hardness. The main drawback of acrylics is their poor solvent resistance, low continuous use temperature (approximately 50 °C) and poor fatigue resistance. Table 3.7 presents a comparison of the performance properties for acrylic cast sheet, PMMA moulding and extrusion compounds and PMMA moulding and extrusion compounds, impact modified. Acrylics come in many different forms such as liquid emulsion for coatings, cast sheet, high impact and general purpose grades.

3.7.2 Applications Cast sheet grades are used for glazing, illuminated and non-illuminated signs, street lamp housing, coach roof lights, guards for machines and food displays, baths and washbasins, and covers on solar panels. High impact grades are used for glazing, signs and displays, and automotive rear light housings. General purpose acrylics are used for bath enclosures, tap tops and accessories, aircraft glazing, signs and displays, automotive rear light housings, car badges and fascia panels. Cast and extrusion sheet represents around two-thirds of total acrylics production, the remainder being injection moulding applications.
3.7.3 Pricing Trends Unlike other engineering plastics, PMMA prices have been fairly stable over the last decade or so. In late 1991, transparent PMMA cost around just over €2,500 per tonne. Prices have fluctuated since then in response to market conditions, but on average prices have been fairly stable. In December 2002, transparent PMMA cost between €2,500-2,750 per tonne. 3.8 Polyphenylene Oxide (Ether) Blends (PPO and PPE)
3.8.1 Properties Modified polyphenylene oxide (PPO) and polyphenylene ether (PPE) resins were first commercialised in the mid 1960s. PPO and PPE are similar in chemical composition and properties 21
Engineering and High Performance Plastics Market Report
and will be discussed as one class of resins. Polyphenylene ether (PPE) is obtained through oxidation-coupling polymerisation of its monomer, 2,6-xylenol, in the presence of oxygen. The modification of these resins involves blending with a second polymer usually polystyrene or polyamide. By varying the blend ratio and other additives, a variety of grades are produced. Unmodified, these polymers are characterised by regular closely spaced ring structures (phenyl groups) in the main molecular chain. This feature along with strong intermolecular attraction causes extreme stiffness and lack of mobility. Their low molecular polarity gives them very low water absorption. Melt processing of the unmodified polymer is extremely difficult. These features lead to high strength, high modulus, excellent dimensional stability, very good impact resistance, and high thermal distortion resistance. The modified polymers retain these properties to a significant degree. The main disadvantage of PPO and PPE blends is that they are easily attacked by some hydrocarbons. They are, however, resistant to many chemicals. Table 3.8 presents a comparison of the performance properties for PPO/polystyrene alloy and PPO/polystyrene alloy with 30% glass fibre-reinforcement.

Key properties of modified PPO/PPE are good electrical insulating properties and long-term dimensional stability due to low moisture absorption. It also has superior impact strength, is lightweight, and is hydrolytically stable. It may be used continuously at temperatures in excess of 80 °C. For enhanced mechanical and thermal performance, glass fibre reinforcement may be added. Because of its alloy matrix composition, PPO/PPE blends are also one of the few non-metallic materials that can be readily electroplated (after an electroless plating surface has been applied using a selective etching process).
3.8.2 Applications Modified PPO/PPE is used for its outstanding properties in a broad range of applications such as automotive, fluid handling (water softener valves, and water pump components), power tools and enclosures (VDU and computers), TV components, washing machine components, electrical insulation and telecommunications.

Engineering and High Performance Plastics Market Report
3.8.3 Pricing Trends PPO/PPE blends cost around €4.05-4.50 per kg in December 2002. PPO/PPE prices tend to be more stable than most other engineering plastics. However, producers managed to push through price increases of about 5.0% in 2000. 3.9 Polyphenylene Sulfide (PPS)
3.9.1 Properties Polyphenylene sulfide (PPS) was first mass-produced by the Phillips Petroleum Company in 1972. PPS is a semi-crystalline polymer made up of alternating sulfur atoms and phenylene rings in a para-substitution pattern. The highly stable chemical bonds of its molecular structure impart a remarkable degree of molecular stability toward both thermal degradation and chemical reactivity. The molecular structure also readily packs into a very thermally stable crystalline lattice. PPS has a high crystalline melting point of about 285 °C (545 °F). Because of its molecular structure, PPS tends to char during combustion, making the material inherently flame retardant. PPS has not been found to dissolve in any solvent at temperatures below about 200 °C. Table 3.9 presents a comparison of the performance properties for PPS unfilled, 30% glass fibrereinforced and 30% long glass fibre-reinforced grades. Table 3.9 Comparison of performance properties for PPS 30% glass 30% long glass Unfilled fibrefibre-reinforced reinforced Elastic modulus (MPa) 3312 n.a. 12420 (tensile with 0.2% water content) Flexural modulus (MPa) 3795-4140 11730 11730 Tensile strength (MPa) (at break) 49-87 152 145 Compression strength (at yield or break) 111 n.a. 224 Hardness (Rockwell R state) 123-125 103 n.a.

When blended with glass fibres and other fillers, PPS has a unique combination of properties including: • • • • •
An excellent combination of both long-term and short-term thermal stability High temperature resistance with continuous use temperature of 230 °C Exceptionally high modulus and creep resistance Outstanding resistance to a wide variety of aggressive chemical environments Precision moulding to tight tolerances with high reproducibility 23
Engineering and High Performance Plastics Market Report
• •
Inherent non-flammability without flame retardant additives Dielectric and insulating properties stable over a wide range of conditions
3.9.2 Applications Automotive is the biggest market for PPS, accounting for over a half of total consumption. The main applications for PPS in automotive are electrical components such as connectors, housings and coil formers, chemical pumps, and car under-the-bonnet components such as brake systems, and electrical/electronic devices requiring high heat resistance, high dimensional stability, and corrosion resistance. Electrical & electronics and industrial applications are also major markets for PPS.
3.9.3 Pricing Trends In December 2002, the average price of PPS was around €7.70-8.50 per kg. Non-reinforced or pure linear grades are at the upper end of the price spectrum, costing around €15-20 per kg. Highly filled compounds with a glass fibre or mineral content are to the lower end of the price range, while high performance types are more expensive. Producers raised prices by 6% in October 2000 due to rising raw material prices. 3.10 Polyetherimide (PEI)
3.10.1 Properties Introduced by GE Plastics in 1982, polyetherimide (PEI) is an amorphous thermoplastic offering outstanding high heat resistance and strength. The high heat resistance and heat stability are attributable to its imide structure. PEI also has resistance to a broad range of chemicals, and is inherently flame resistant with low smoke emission. A major component of PEI is bisphenol A, which is also produced by GE Plastics, mainly for use in polycarbonates. Polyetherimide is a hybrid between polyarylethers and polyimides. The imides impart high temperature performance and the inclusion of ether groups allows melt processing. The properties of PEI are in fact closer to PES than to non-melting polyimides. PES and PEI therefore compete directly in many applications. The main advantages of PEI are its high tensile strength at 20 °C more than either PES or polysulfone. It also has lower water absorption than PES. Continuous use temperature is around 170 °C compared to PES of 180 °C. The main disadvantage is that stress cracking occurs when in contact with chlorinated solvents. Table 3.10 presents a comparison of the performance properties for unfilled polyetherimide and 30% glass fibre-reinforced grades.

3.10.2 Applications A wide range of high performance applications have been developed for polyetherimide resins. The main markets for PEI resin and compounds are electrical/electronic applications, aircraft/aerospace interiors, food service (ovenable), high temperature lighting bezels and reflectors, medical instrument trays, institutional kitchenware and under-hood automotive applications. Automotive applications account for around a half of PEI market volume.
3.10.3 Pricing Trends Polyetherimide is one of the most expensive high performance polymers. At the end of 2000, the average price of PEI was around €9.50-10.5 per kg. PEI prices have been fairly stable in the last two years. 3.11 Polysulfone (PSU), Polyethersulfone (PES)
3.11.1 Properties PES and PSU were first commercialised by BASF in 1965. They are semi-transparent, very high temperature resistant amorphous thermoplastics that are used where the performance requirements exceed the capabilities of other engineering plastics such as polyamide, PBT and polyacetals. PES and PSU can also replace thermosets, metals and ceramics. The main features of these polymers are their high stiffness, high continuous operating temperatures, high mechanical strength, good electrical insulation properties and good dimensional stability. The continuous operating temperature of PES at 204 °C is much higher than for PSU at 174 °C. PSU and PES are hydrolysis resistant in hot water and steam at temperatures of up to 149 °C (300 °F). They also offer high chemical resistance to acidic and salt solutions, and good resistance to detergents. The main drawbacks of PSU and PES are their susceptibility to stress cracking in certain solvents and poor weathering properties.

Engineering and High Performance Plastics Market Report
PES and PSU resins are often reinforced with glass or carbon fibre for additional strength. Table 3.11 presents a comparison of the performance properties for 30% glass fibre-reinforced grades of PSU and PES.

3.11.2 Applications The main areas of application for these polymers are electrical and electronic engineering, chemical engineering and automotive.
3.11.3 Pricing Trends In December 2002, the price range for PSU/PES compounds was €5-8 per kg for large orders. Highly filled compounds were at the lower end of the price spectrum. PSU/PES prices have been fairly stable in recent years. 3.12 Polyphenylene Sulfone (PPSU)
3.12.1 Properties PPSU is the highest performance amorphous polymer and made by the reaction of 4,4´dichlorodiphenylsulfone (DCDPS) with bisphenol. The material is used in very demanding, high temperature applications. Heat deflection temperature is 207 °C (405 °F), it can withstand continuous exposure to heat and still absorb extremely high impact without deflecting or breaking. Its chemical resistance is higher than most other amorphous polymers.
3.12.2 Applications PPSU is most widely used in the medical market. Medical devices require high strength materials to sustain repeated sterilization, while maintaining their performance. PPSU resin offers extremely high impact strength plus excellent chemical resistance, which allows it to successfully withstand
26
Engineering and High Performance Plastics Market Report
repeated steam sterilization and harsh boiler additives. PPSU is also extremely resistant to stains caused by disinfecting solutions. Medical applications for PPSU include medical trays and containers, surgical instruments, a binocular ophthalmoscope and a bellow housing for anaesthetics. Other applications for PPSU are institutional food service trays and aircraft interiors. Solvay Advanced Polymers is the world’s only producer of PPSU under the Radel R trade name. Radel R resin can be injection moulded, vacuum formed or machined. 3.13 Liquid Crystal Polymers (LCP)
3.13.1 Properties Liquid crystal polymers are wholly aromatic polyester polymers that were first launched in the late 1980s. However the advance in liquid crystal polymers has taken longer than anticipated because of their high cost relative to competing materials such as PPS. A characteristic feature of LCP is the molecular structure. These polymers consist of rigid rod-like macromolecules, which align in the melt to produce liquid crystal structures. If a liquid crystal polymer melt is subjected to shear or stretching flow, as in the case of all thermoplastic processing operations, then the rigid macromolecules order themselves into fibres and fibrils, which are frozen when the melt cools. This is how the specific morphology of LCP is formed in the solid state. Table 3.12 presents a comparison of the performance properties for unfilled, 30% mineral filled and 30% glass fibre-reinforced grades of liquid crystal polymers. Table 3.12 Comparison of performance properties for LCP 30% mineral 30% glass fibreUnfilled filled reinforced Elastic modulus (MPa) 9660-19320 4071 4830-20700 (tensile with 0.2% water content) Flexural modulus (MPa) 2760-6210 9660 11454-14490 Tensile strength (MPa) (at break) 110-187 111 117-207 Compression strength (at yield or 43-132 n.a. 69-145 break) Hardness (Rockwell R state) 76 n.a. 77-87 Coefficient of thermal expansion 5-7 8-22 5-78 (10-6/ºC) Deflection temperature (ºC) 180-355 235 205-277 Specific gravity 1.35-1.84 1.63 1.6-1.67 Water absorption 0-0.01 n.a. 0.05 (% weight increase, saturated) Dielectric strength (V/mil) 800-890 n.a. 640-1000 Melting temperature (ºC) 280-421 n.a. 280-680 Processing temperature (ºC) 283-410 349-366 291-410 Moulding pressure (MPa) 7-111 28-56 7-97 Compression ratio 2.5-4 2.5-3 2.5-4 Linear mould shrinkage (cm/cm) 0.001-0.006 n.a. 0.001-0.09
LCPs have excellent dimensional stability and creep resistance, especially at very high temperatures. Continuous use temperature is about 240 °C. LCPs are highly resistant to many
27
Engineering and High Performance Plastics Market Report
chemicals, including concentrated acids, bases and hydrocarbons. They also display outstanding fatigue resistance and high dielectric strength performance over a very wide temperature range. In addition, LCP has substantial processing advantages over other types of high performance thermoplastics with very short cycle times. Tests have shown cycle times of < 1 second and for a production batch of 1 million components, the lower production costs of LCP far outweighed the lower material costs of for example, PA46. On the downside, LCP requires drying and careful attention to part design. LCP has low weld line strength and low toughness with fracture behaviour resembling that of wood.
3.13.2 Applications These properties make them especially suitable for precision electrical and electronic components, connecting parts in fibre optic cables, telecommunications devices, chemical processing machines, medical devices, automotive under-the-bonnet components, aerospace and machinery components. A variety of filled and reinforced products are available, including carbon, glass fibre, mineral and graphite, which allows the basic polymer to be adapted to the requirements of many areas of application. A key driver of LCP growth has been their replacement of moulded parts previously made from metal, thermosets and other advanced thermoplastics in the electronics and telecommunication industries. The trend in these markets to miniaturization and greater precision as well as demand for more heat resistant materials has also boosted demand for LCPs.
3.13.3 Pricing Trends Producers raised prices by €1.28 per kg at the end of 1999 due to cost pressure. At the end of 2002, LCP prices ranged from €20-30 per kg, depending on the grade and application. While LCP is more expensive than most other engineering plastics, the total systems cost of applying LCP is extremely favourable. LCP has very short cycle times for example, that are unmatched by any other material. 3.14 Polyetheretherketone (PEEK)
3.14.1 Properties Polyetheretherketones are high performance, semi-crystalline, melt processable materials with a unique combination of properties. PEEKs can be made by two general routes. In both cases the main difficulty is to keep the crystallisable polymer in solution. Formation of the carboxyl link by polyaroylation can be carried out in liquid HF by catalysts such as BF3. The reaction is also possible in solvents such as dichlorobenzene with an excess of AlC13 both to catalyse the reaction and to solubilise the polymer by complexing with the carbonyl group in the backbone. AlC13 must then be neutralized and extracted from the polymer. The waste stream contains organic compounds, aluminium salts and hydrochloric acid. The alternative is to form the ether link via displacement of activated halogen atoms by phenoxide anions. Hence PEEK can be manufactured from 4,4´-difluorobenzophenone and hydroquinone. The polymer is then isolated by removal of the alkali metal fluoride and the polymerisation solvent.

A comparison of key performance properties for three different grades of PEEK polymers is summarised in Table 3.13. Table 3.13 Comparison of performance properties for PEEK Standard viscosity 30% glass fibregrade for injection reinforced moulding Relative density (crystalline) 1.32 1.49 Continuous use temperature (ºC) 260 260 Melting point (ºC) 343 343 Flexural strength at 23 ºC (MPa) 170 250 Tensile strength (MPa) (at 23 ºC) 97-100 156-157 Hardness (Rockwell R state) 126 124 -5 Coefficient of thermal expansion (10 /ºC) 4.7 2.2 Water absorption (% weight increase, saturated) 0.5 0.11 Dielectric strength (V/mil) 190 n.a.
The main features are: • • • • • • • •
High temperature performance – a continuous service temperature of up to 260 °C (500 °F) with excellent electrical and mechanical properties retained Melt temperature of 343 °C High strength and toughness over a wide range of temperatures Excellent resistance to a very wide range of organic and inorganic liquids at elevated temperatures Excellent friction and wear properties Low flammability Hydrolysis resistance Electrical properties – remains stable over a wide range of temperatures and frequencies.
PEEK can be processed on all conventional processing technologies with modification made for higher processing temperature of 350 to 400 °C. The plastification units require high temperature steel thus ensuring the components have a long lifespan. Special wear layers are only advisable for filled grades, as with all other high temperature materials. The mould temperature for injection moulding of PEEK should be in the range 180-200 °C for thin-walled, complex parts, and also filled PEEK parts. This is essential to achieve optimum crystallisation.
3.14.2 Applications PEEK, produced by Victrex plc, is the market leading polyketone. PEEK can be used in very demanding applications as a replacement for metal. Key markets are aerospace, transportation, industrial, electronics, medical and the food processing industry.
3.14.3 Pricing Trends PEEK is the most expensive of the high performance plastics. In December 2002, PEEK cost between €75-80 per kg. Prices are however more stable than most other engineering resins.

3.15 Polyphthalamide (PPA)
3.15.1 Properties Polyphthalamide (PPA) is a semi-crystalline engineering polymer that bridges the costperformance gap between traditional engineering thermoplastics such as polycarbonate (PC), polyamides (PA), polyester (PET, PBT), acetals (POM) and higher-cost speciality polymers such as liquid crystal polymers (LCP), polyphenylene sulfide (PPS) and polyetherimide (PEI).

PPA resin has excellent mechanical properties (e.g., strength, stiffness, fatigue, creep resistance) over a broad temperature range. Compounded grades are available in a wide range of unreinforced and reinforced formulations. Unreinforced grades are designed for general-purpose injection moulding and extrusion applications that require high surface gloss, lubricity, low warpage and toughness, along with a high level of mechanical performance at elevated temperature.
3.15.2 Applications Key market sectors for PPA are: •
Automotive: sensors and solenoids, halogen lamp sockets and fog lamp assemblies, motor end caps and housings, fuel system components, anti-lock braking system components, cooling and heating system components.
•
Electrical & electronics: high brightness LEDs, SMT electronic components, capacitor and chip carriers, heat sinks and switches
30
Engineering and High Performance Plastics Market Report
•
Consumer and industrial markets: vacuum cleaner impellers, lawn and garden machine components, oil well drilling components, valve stems and handles (plumbing). PPA resin has a wide range of features that are beneficial in numerous consumer applications. PPA offers low thermal conductivity and good heat resistance, along with retention of strength and rigidity at elevated temperatures, to provide long-lasting service in lawn and garden tool components. The outstanding impact resistance, rigidity, and strength at elevated temperatures are key reasons for PPA being used for vacuum cleaner impellers.
•
Industrial markets: PPA resin has a wide range of features that make it useful for various industrial applications. For example, its superior impact resistance, especially at sub-zero temperatures, combined with its good chemical resistance in down-hole environments, makes it an excellent choice for oil well drilling components.
3.16 Polyarylamide
3.16.1 Properties Polyarylamide is a semi-crystalline polymer that offers very high rigidity for a polymeric material due to its glass transition temperature of approximately 85 °C (185 °F). Other key properties are its high strength (flexural strength as high as 400 MPa), very low creep (deformation of less than 1% after 1000 hours under 50 MPa), excellent surface finish, ease of processing and slow rate of water absorption. Polyarylamide has good resistance to most common solvents, aqueous solutions and engine oils. However, it is degraded by strong and concentrated mineral acids, powerful oxidants and strong bases. It is sensitive to certain organic acids and to some solutions of metallic salts. Also, it is recommended that their use should be carefully considered where the product is continuously in contact with water.
3.16.2 Applications Polyarylamide has replaced metal in many fields of application. •
Automotive and transportation: fuel pumps, cam covers, vandal-proof seats, rear-view mirror housings, clutch parts, wiper controls, oil filter bodies, headlamp control pivots, door handles, seat adjustment mechanisms, headlamp surrounds.
•
Electrical & electronics: connectors, chassis and housings for electrical and electronic equipment, sliding parts in video recorders, safety switches, disk supports in CD players, induction motor supports, telecommunications parts.
•
Domestic appliances: electric razor heads, electric iron parts, vacuum cleaner motor supports, sewing machine parts.
•
Other markets: leisure industry applications, machine tools, furniture, medical.
Solvay Advanced Polymers is the world’s only producer of polyarylamide. The Ixef resins are produced in the USA and compounded at Oodenarde, Belgium, in a 10,000 tpa compounding plant
31
Engineering and High Performance Plastics Market Report
3.17 Polyamide-imide (PAI)
3.17.1 Properties Solvay Advanced Polymers is also the world’s only producer of polyamide-imide with its Torlon product range. Polyamide-imide is produced from a reaction between trimellitic, anhydride, and various diamines. It has a high melt viscosity and is reactive in the melt state. Accordingly, it is not possible to reduce viscosity by raising temperature. Injection moulding requires heavy duty, high rate machines, preferably using hydraulic accumulators. It is also possible to compression mould and extrude into stock shapes.
3.17.2 Applications PAI offers similar outstanding performance in extreme environments to thermosets. These resins have exceptional strength at high temperature with excellent resistance to creep, wear and chemicals, including organic solvents. PAI is also used in coating applications, due to its outstanding surface adhesion to many different materials including metals and polytetrafluoroethylene. PAI is mainly used in injection moulding applications and has been replacing metal in a range of automotive and electrical & electronics applications in recent years. Examples include: •
Precision components for demanding electronic handling operations such as test sockets that are used to protect delicate devices during robotic handling and high-speed, high-force compression into electrical test sockets.
•
Parts for military aircraft, automotive transmissions and off-highway equipment, including hydraulic parts, seal rings, washers and bushings.
•
Test sockets that are used to protect delicate devices during robotic handling.
•
Seal adapters on testing units for printed IC boards. These must be sealed to maintain test temperatures from –50 °C to 150 °C (–58 °F to 302 °F), and PAI can provide better dimensional stability for a tighter seal fit and offer longer part life than traditional materials.
3.18 Developing Materials Several new types of resin have been developed in recent years.
3.18.1 Cyclic Olefin Copolymers Cyclic olefin copolymers (COC) are an amorphous glass clear copolymer of ethylene and norbornene, made via proprietary metallocene catalysts. The material was developed by Ticona GmbH and is now being marketed under the Topas trade name. The principal performance properties of COC polymers are: • • • • 32
low density high transparency extremely low water absorption very high water vapour barrier properties
Engineering and High Performance Plastics Market Report
• • • • •
graded heat distortion temperature (HDT/B) up to 170 °C high rigidity, strength and hardness good resistance to acids and alkalis very good electrical insulating properties very good processability/flow properties
Topas is mainly suitable for the production of transparent parts. Main areas of application development include: • • • • • • •
medical devices and diagnostic disposables (prefillable syringes, cuvettes, bottles, microplates, microstructured parts) lighting sector (lenses, components) optics (lenses, sensors, displays, light guides) optical data storage speciality films primary packaging of pharmaceuticals, blister packs, shrink caps, sleeves and stand-up pouches blends of Topas COC with a variety of polyolefins for packaging films, etc.
Ticona is initially developing injection moulding and film packaging applications for COC. Production of COC is located at a 30,000 tpa plant at Oberhausen, Germany.
3.18.2 Syndiotactic Polystyrene Dow Chemicals Questra syndiotactic polystyrene is a new semi-crystalline engineering polymer. The main performance properties of Questra include high heat resistance, lightweight, electrical properties, chemical resistance and processability. These polymers are impact, chemical and glycol resistant as well as ideal for medium and high heat environments. Grades include mineral and glass fibre-reinforced, medium heat, impact resistance, high heat and chemical resistance. Questra resins are used predominantly in automotive applications such as chassis/powertrain, electrical and coolant systems. Syndiotactic PS competes mainly with PBT, polycarbonate and ABS.
3.18.3 Cyclic Butylene Terephthalate (CBT) Dow Automotive entered an alliance with Cyclics to develop cyclic butylene terephthalate (CBT) resins for automotive applications. Research will focus on a number of automotive structural composites, including vertical and horizontal body panels and truck boxes. The companies expect that components will be able to be formed using a number of techniques, including compression and injection moulding. CBT resins will contribute to lighter weight vehicle design and be recyclable.
3.18.4 Copolycarbonate In 1996, Dow Plastics introduced a new family of advanced copolycarbonate resins, which provide a cost-effective alternative to existing high-performance amorphous polymers. The ‘Inspire’ advanced copolycarbonate resins offer equivalent or better high-heat performance than other highheat amorphous polymers at a cost advantage. Generally, manufacturers and moulders are forced to choose between lower-cost engineering thermoplastics, which, in some cases, do not provide acceptable heat performance, and advanced polymers, which provide acceptable high-heat performance, but at a significant price premium. ‘Inspire’ resins provide an alternative for manufacturers who require the heat performance associated with advanced polymers (e.g.,
33
Engineering and High Performance Plastics Market Report
polysulfone, polyetherimide and polyethersulfone), but who are looking for a more cost-effective solution. The new advanced copolycarbonate resins are a copolymer of bisphenol A and bishydroxyphenol fluorene (BHPF), a fluorenyl derivate. Among the primary features of Inspire resins are equivalent or better heat and inherent ignition resistance without the use of halogens, improved processability, and superior transparency and optical properties when compared to advanced polymers.

Total GDP of the European Union countries increased by only 1.6% in 2001 against 3.4% in the previous year. US economic growth fell from 3.8% in 2000 to just 0.3% in 2001, while the Japanese economy contracted by 0.3%. The US economy recovered in 2002 to register growth of 2.3% but the European Union and Japan experienced a further deterioration in their economic growth. GDP in the EU rose by only 0.9% in 2002 and Japan experienced a further reduction of 0.7%. The latest OECD projections indicate a slow and modest recovery in economic growth during the next two years. The US economy is forecast to grow by 2.6% in 2003 and 3.6% in 2004. The European Union is expected to grow by 1.9% in 2003 and then by 2.7% in 2004. Japan will continue to show the lowest growth rates of the world’s major economic region with growth forecasts of just 0.8-0.9% during the next two years. However, even these forecasts may be optimistic given the dampening effect that the war in Iraq is having on world economic growth.

Engineering and High Performance Plastics Market Report
In 2002, total world consumption of engineering and high performance plastics is estimated at 10,860,000 tonnes. This represents approximately 7% of total world plastics consumption. Demand for engineering and high performance plastics has outperformed most other plastic types in recent years. During the period 1995-2000, the average growth in consumption of engineering and high performance plastics was around 8.5% per annum compared to 6.5% per annum growth in standard thermoplastics. The principal drivers of demand for engineering and high performance plastics are replacement of traditional materials such as metal and thermosets, development of new applications and strong growth in key end user markets such as electronics, telecommunications and automotive. The downturn in world economic growth and collapse of the IT/telecom sectors led to a reduction in demand for engineering and high performance plastics in 2001. World consumption fell by 6% from just over 11,000,000 tonnes in 2000 to 10,400,000 tonnes in 2001. Demand recovered slightly in 2002, although total world consumption remains below the 2000 level. In 2007, world consumption of engineering and high performance plastic is projected at 13,497,000 tonnes. This represents a compound annual growth rate of 4.5% for the period 2003-2007. The projected growth rates for all polymer types are lower than were experienced during the boom time of the late 1990s. This is because of the sharp downturn in world economic activity that has occurred since 2001, and the uncertain prospects for any substantial recovery in demand for at least another couple of years. Furthermore, major application areas for engineering plastics in particular, are becoming mature, and therefore the opportunities for further material substitution are more restricted. High performance plastics such as PEEK, LCP and the sulfone-based polymers will grow at double-digit rates during the next five years, as the potential for material substitution is much greater for these polymers. In contrast, the more mature engineering plastics such as ABS, polyacetal and acrylics, will show the lowest rates of growth during the next five years. The most widely used engineering plastic is ABS with total world consumption of 4,667,000 tonnes in 2002. Polyamide is the second largest category with total consumption of 1,950,000 tonnes, followed by polycarbonate with 1,714,000 tonnes. Acrylics, polyacetal and PBT are also well-established and high volume engineering plastics. PPO/PPE blends are the most widely used of the high performance plastics with market tonnage of 353,000 tonnes in 2002. It should be noted however that this figure represents PPO/PPE compounds with other polymers such as polystyrene and polyamide, which vastly overstates the actual PPO/PPE resin content. PPS is the most widely used of the sulfone polymer types with total world consumption of 50,000 tonnes in 2002. PSU/PES market tonnage is 23,000 tonnes. Liquid crystal polymers and polyetherketones are the smallest groups in terms of market volume, but are the most costly polymers and are growing at the fastest rate. Table 4.3 shows consumption of engineering and high performance plastics by world region for the period 1999-2002. North America is the largest consumer of engineering and high performance plastics with total demand of 3,540,000 tonnes in 2002. Asia Pacific, excluding Japan, is the next most important user with consumption of 3,459,000 tonnes. The market share of Asia Pacific can be explained by the high concentration of ABS production and consumption in the region, and particularly in China. Western Europe with 2,548,000 tonnes is the third largest consuming region, followed by Japan with 1,116,000 tonnes.

Asia Pacific, excluding Japan, is increasing its share of engineering and high performance plastics consumption faster than any other region. Between 1999 and 2002, China and other Pacific Rim countries, raised their share of total consumption from 28.5% to 31.0%. This is due mainly to the growing trend for automotive and electrical and electronics companies to shift manufacturing facilities to lower cost economies. During the same period the shares of both Japan and North America declined. This is largely explained by the economic downturn and growing market maturity for many key applications. The share of Western Europe has also increased slightly during the last three years to reach 23.5% in 2002. Other world regions such as Latin America account for a very small percentage of total world consumption, although their share is growing.

which include domestic and electrical appliances and power tools, are the next most important market, followed by industrial and ‘other markets’. Table 4.6 shows the percentage share of world engineering and high performance plastic consumption by market sector for the period 1999-2002. Table 4.6 Percentage share of engineering and high performance plastic consumption by market sector, 1999-2002 1999 2000 2001 2002 Automotive 26.4% 26.6% 26.3% 26.3% Electrical & Electronics 23.9% 23.8% 23.4% 23.4% Consumer products 18.4% 19.1% 19.7% 19.8% Industrial 15.7% 15.1% 15.0% 15.1% Other 15.6% 15.4% 15.5% 15.5%
Growth in the E&E sector was the principal driver of plastics demand during the latter part of the 1990s. However, the slowdown in the electronics and telecom sectors has resulted in lower demand for engineering plastics, and hence a declining share of the total market since 1999. The share of the automotive industry has remained steady during the last three years, but industrial markets have declined. The fastest growing sector has been consumer products with an increase in share from 18.4% to 19.8% between 1999 and 2002. The main reason for the better performance of consumer products has been the greater resilience of consumer spending in the face of an economic downturn. 4.2 Demand Trends by Polymer Type, 1999-2002
4.2.1 Polyamide (PA) Table 4.7 shows world consumption of polyamide by sector for the period 1999-2002.

In 2002, total world consumption of polyamide was 1.95 million tonnes. About 90% of total consumption is PA6 and PA66, with roughly two-thirds PA6, and one-third PA66. The remaining 10% comprises PA11, PA12 and various copolymers. Between 1998 and 2000, the average annual growth in world polyamide resin consumption was 8.5%. In 2001, world demand was down by just over 7% due to the downturn in major markets such as automotive and E&E. Demand recovered by an estimated 4.9% in 2002 with the Asia Pacific region registering the fastest growth. Western Europe grew in line with the world market, while consumption in the USA and Japan grew more slowly. For the period 2002-2007, world polyamide consumption is projected to increase at a compound annual growth rate of between 4-5%, which is somewhat lower than recent historical growth trends. Lower world economic growth and maturing markets are the main factors restraining future growth

In 2002, total world consumption of PBT resin was 476,000 tonnes. Assuming a filler content of approximately 45%, this equates to around 700,000 tonnes of PBT compounds. Between 1995 and 2000, the average annual growth in world PBT resin consumption was just over 5.0%. In 2000, demand for PBT increased considerably worldwide with growth at 11.3%, due in particular to strong growth in key end user markets such as automotive, telecommunications and electrical goods. World demand fell however by 6-7% in 2001 due to the downturn in automotive and the E&E sector. Consumption of PBT recovered in 2002 by 5.0% with the Asia Pacific region registering the fastest growth. Growth rates in Western Europe and North America were between 45% in 2002, while demand in Japan increased by just over 3.0%. For the period 2002-2007, world PBT consumption is projected to increase at a compound annual growth rate of between 5-6%, which is about in line with recent historical growth trends. Market growth will be bolstered by further product improvement, new applications development and new technologies, with the automotive sector in particular, continuing to be a key driver. Table 4.11 shows percentage share of total world PBT consumption by region for the period 19992002.

In 2002, total world consumption of ABS was 4.67 million tonnes. Between 1990 and 2000, the average annual growth in world ABS resin consumption was 7.0%. In 2001, demand fell by 5.1% due to the downturn in major markets such as automotive, consumer products and E&E. World demand recovered by 3.8% in 2002 with the Asia Pacific region, excluding Japan, showing the fastest growth. Demand in Western Europe and North America grew by around 1% in 2002. For the period 2002-2007, world ABS consumption is projected to increase at a compound annual growth rate of around 2-3%, which is somewhat lower than recent historical growth trends. The European and North American markets are very mature users of ABS and consumption will grow in line with real GDP. China on the other hand, is a fast developing market and will increase consumption at an annual rate of around 5-6%. Table 4.14 shows percentage share of total world ABS consumption by region for the period 19992002. Table 4.14 Percentage share of world ABS consumption by region, 1999-2002 1999 2000 2001 2002 Western Europe 14.3% 14.8% 14.0% 13.6% North America 37.3% 35.2% 35.2% 34.3% Japan 9.2% 8.9% 8.7% 8.6% Rest of Asia Pacific 39.2% 41.2% 42.1% 43.5%
Asia Pacific, and most notably China, is the largest consumer of ABS with 43.5% of total world consumption in 2002. With consumption of around 2.0 million tonnes in 2002, China is the leader in ABS processing by far. In addition to its domestic production of 600,000 tpa, China has had to import in excess of 1.3 million tonnes of ABS, mostly from Taiwan (45%), Korea and Japan. Over the next few years, the annual growth rate of approximately 8% is expected to lead to a further widening of the demand gap to as much as 1.6 million tonnes by 2005, despite the rising domestic capacities. North America consumes 34.3% of world ABS production, Europe 13.6%, and Japan the remaining 8.6%. While China is growing its share of world ABS consumption, Japan, Europe and the USA have witnessed a small reduction in their shares since 1999. Table 4.15 shows percentage share of total world ABS consumption by market sector for the period 1999-2002.

World consumption of polycarbonate amounted to 1.7 million tones in 2002. Polycarbonate has been one of the ‘star’ performers’ in the engineering plastics sector in recent years. Between 1995 and 2000, the average annual growth in world polycarbonate consumption was 15-20%. In 2001 however, there was a major contraction in demand for polycarbonate with world consumption falling by 6-7%. This was largely attributable to the downturn in major markets such as automotive, construction and E&E, but also to relatively high stocks that converters had built up in previous years. The US market saw a decline in polycarbonate consumption of over 16% in 2001, with Japanese consumption lower by over 14%. The decline in Europe was more modest at just over 6.5%, while ‘other Asia Pacific’ countries showed demand growth in excess of 5%. In 2002, world demand recovered by 5.7% with the Asia Pacific region and the ‘rest of the world’ registering the fastest growth. Western European demand grew by 6.3%, while consumption growth in the USA and Japan was much more modest. For the period 2002-2007, world polycarbonate consumption is projected to increase at a compound annual growth rate of between 8-10%, compared with 15-20% achieved in the period 1995-2000. Nevertheless, this growth projection remains above average for the engineering plastics sector. While lower world economic growth and maturing markets will have a dampening effect on future growth, demand will be bolstered by continuous product development, new applications development and fast growing end user markets. Optical media, particularly DVDs, will continue to be the main driving force of the market for the foreseeable future. There are also good growth prospects for PC/ABS blends because of their inherent flame retardant properties, medical devices and automotive glazing systems.

Consequently, the share of homopolymers has dropped from 25% in 1997 to 22% in 2001. World POM consumption has been growing at a lower rate than the engineering plastics market as a whole. Between 1995 and 2000, the average annual growth in world polyacetal consumption was 6.0%. In 2001, demand was lower by 3% due to the downturn in major markets such as automotive and E&E. Demand recovered by an estimated 2.2% in 2002 with the Asia Pacific region registering the fastest growth. Western Europe and North America grew in line with world market demand as a whole, with consumption growth in Japan continuing to fall. In Japan, domestic demand for POM has been on a downward path since the early 1990s. The main reason for reduced demand is the shift in automotive and electrical goods production from mainland Japan to other Asian countries where production costs are lower. For the period 2002-2007, world polyacetal consumption is projected to increase at a compound annual growth rate of between 3-4%, which is somewhat lower than recent historical growth trends. The more mature North American and European markets will grow at a lower rate while China and other developing Asian economies will grow POM consumption by around 7% per annum. POM consumption in Japan will continue to stagnate. Future demand for POM will, however, be sustained by product and applications development. In automotive markets, POM is expected to make further inroads in under-the-bonnet, electrical systems and interior applications. The use of POM for car interior applications for example, should be boosted by the development of odour-free products, which overcome the problem of odour emissions previously associated with use of polyacetal inside the car. Other interesting product developments expected to encourage greater use of POM in the car include the use of so-called outsert technology (metal-plastic composites), and the combination of POM with injection moulded ‘soft’ components, including NBR rubber and polyester elastomers. Another interesting growth market for POM is medical technology, where new applications are being found. For example POM is being used for production of housings in needleless injection systems and also for inhaler casings. Consumer products and sports equipment markets also have positive growth potential. Table 4.20 shows percentage share of total world polyacetal consumption by region for the period 1999-2002.

Total world consumption of PMMA was 988,000 tonnes in 2002. Cast sheet, extrusion sheet and moulding compounds each account for roughly a third of total production. Between 1997 and 2000, the average annual growth in PMMA consumption for the mature markets of Western Europe and the USA was only 2-3%. In contrast, China and the Pacific Rim countries have witnessed much higher growth. Demand for PMMA is expanding rapidly in these countries, especially in the areas of signboards, light fixture covers, automotive tail-light covers and aquarium tanks. In 2001, global PMMA demand was down by just over 5% due to a slowdown in major markets such as construction and lighting and the automotive industry. Consumption fell sharpest in Japan, Europe and North America. Global demand recovered by an estimated 5-6% in 2002, with Europe experiencing the fastest growth. China and Pacific Rim countries were not far behind. North American and Japanese demand showed only a small recovery in 2002. For the period 2002-2007, world PMMA consumption is projected to increase at a compound annual growth rate of between 3-4%. The more mature North American and European markets will grow at around their historical trend rate of 2-3% per annum, while China and other developing Asian economies will show much higher growth in PMMA consumption. In contrast, the Japanese market will continue to stagnate. Table 4.23 shows percentage share of total world PMMA consumption by region for the period 1999-2002.

Total world consumption of PSU/PES was estimated at 22,700 tonnes in 2002 compared with peak demand of 22,900 tonnes in 2000. Between 1995 and 2000, the global PSU/PES demand increased at an annual rate of between 15-16%. In 2001, global PSU/PES demand declined by 5.3% due to the sharp downturn in key market sectors. There was a modest recovery in world demand during 2002, with estimated growth of 4.7%. For the period 2002-2007, world PSU/PES consumption is projected to increase at a very respectable compound annual growth rate of between 10-11%. Growth will however be lower than the historical trend rate due to the downturn in demand from key markets and maturing applications. Table 4.35 shows percentage share of total world PSU/PES consumption by region for the period 1999-2002. Table 4.35 Percentage share of world PSU/PES consumption by region, 1999-2002 1999 2000 2001 2002 Western Europe 19.2% 19.7% 19.2% 19.4% North America 58.7% 58.3% 58.7% 57.1% Japan 11.1% 11.0% 10.9% 11.2% Rest of Asia Pacific 11.1% 11.0% 11.3% 12.2%

In 2002, total world consumption of LCP amounted to 17,800 tonnes against peak demand of 18,000 tonnes in 2000. LCP is a relatively new material that has established a strong market position in recent years because of its unique properties. Between 1997 and 2000, global demand for LCP grew at an annual average rate of between 15-20%. The main driving force was the strong growth in key end user sectors such as telecommunications and electronics. In 2001, global LCP consumption declined by 9-10% due to a downturn in key applications such as cellular phones and personal computers. In Japan, LCP consumption fell by 15-20% due to a sharp contraction in US demand for IT products, a major market for Japanese producers. European and North American demand was down by 5-10% in 2001. There was a sharp recovery in global demand last year with an estimated growth rate of 8.6%. Asia showed the highest growth, but there were also strong performances from Europe and North America. The prospect for LCP growth over the next few years is positive. For the period 2002-2007, world LCP consumption is projected to increase at a compound annual growth rate of between 12-15%. More stringent customer material specifications and future technological developments requiring a very high speed of innovation will fuel market demand. New standards such as Universal Mobile Telecommunications System (UMTS) and Bluetooth will open up new growth markets for LCP. Also, portable information devices are expected to grow further and LCP is extending its reach into fibres and films. Table 4.38 shows percentage share of total world LCP consumption by region for the period 19992002. The Asia Pacific region, and Japan in particular, is the largest consumer of LCP, with 58.2% of global demand in 2002 because of the high concentration of electrical goods produced in the region. North America represents 27.6% and Western Europe the remaining 14.2%. The European 51

PEEK has enjoyed substantial growth in demand during the second half of the 1990s. Between 1995 and 2001, global demand for PEEK grew at an annual average rate of between 15-20%. The excellent balance of properties has enabled PEEK to replace traditional materials in many demanding applications. PEEK has also benefited from strong growth in mobile phones and the Internet during the last decade. However, in 2002, total world consumption of PEEK fell by around 23% to 1,300 tonnes. This was due to the general economic downturn and particularly to the major reduction in sales of semiconductors. Demand from the key US market fell sharpest because of a fall-off in sales to the electronics market. Asia Pacific volumes were down by 25% while European volume fell by around 15%.

Engineering and High Performance Plastics Market Report
The prospect for PEEK growth over the next few years is positive. For the period 2002-2007, world PEEK consumption is projected to increase at a compound annual growth rate of between 12-15%. New applications development continues to drive demand for PEEK. According to Victrex, the leading PEEK producer, there were 249 new applications in 2002 compared with 184 in the previous year. Other reasons for optimism about future prospects are the Invibio medical implants business, which is performing ahead of expectations, and the technical development of the Victrex proprietary ionomer for the fuel cell alliance with Ballard Power Systems, which is also progressing well, with Ballard not proceeding with further development of its own ionomer for the time being. Injection moulding applications are growing at the fastest rate. Stock shapes have traditionally been the largest market, but now compounding takes about the same volume. Over 50% of new applications in 2001 involved injection moulding. Film and extrusion blow moulding uses are also expanding. Table 4.41 shows percentage share of total world PEEK consumption by region for the period 1999-2002. Table 4.41 Percentage share of world PEEK consumption by region, 1999-2002 1999 2000 2001 2002 Western Europe 48% 47% 48% 52% North America 42% 43% 42% 38% Asia Pacific 10% 9% 10% 10%
Europe is the largest consumer of PEEK with 52% of global demand in 2002. North America represents 38% and Asia accounts for the remaining 10%. Table 4.42 shows percentage share of total world PEEK consumption by market sector for the period 1999-2002.

Automotive is the largest user of PEEK with a share of 41% of total world consumption in 2002. Industrial applications are the next most important sector with 26%, followed by electronics and telecoms with 20%. ‘Other markets’, including medical and developing applications, represent the remaining 13% of world PEEK demand. The share of electronics and telecoms is higher in Asia than in Europe because of the large number of equipment manufacturers located in the region. Likewise, the share of the automotive sector is much higher in Europe, at around 50% of PEEK demand, than in Asia.

5 Automotive Applications for Engineering and High Performance Plastics 5.1 Introduction In 2002, the automotive industry consumed 2,851,000 tonnes of engineering and high performance plastics. Automotive demand was growing at between 7-8% per annum during the three years to 2000. However, consumption fell sharply in 2001 due to the downturn in world economic activity. There was a steady recovery in demand last year, but total consumption remains below 2000 levels. Engineering polymers and high performance plastics are used to manufacture more demanding applications in the car. The most valued properties of engineering plastics for automotive applications are their high heat resistance, dimensional stability, strength and resistance to a range of chemicals. These properties have led to their replacement of traditional materials such as metal and thermosets in motor vehicles. Polycarbonate and acrylics have also been replacing glass in light lenses and instrument panel displays. The use of plastic has grown significantly in automotive applications during the last two decades. This is due in particular to its lightness and hence greater fuel efficiency than metal, Plastic also offers greater design flexibility, reduces development time and lowers assembly costs. In Europe, the use of plastics in automotive manufacturing increased by 115% between 1990 and 2000 to 2.75 million tonnes. This represents an increase of about 40 kg per car, from 70 kg in 1980 to 110 kg per car in 2000. Plastic now accounts for around 9.5% of the total weight of the average passenger car. Various polymers are used in over 1,000 different parts of all shapes and sizes, from instrument panels and interior trim to bumpers and radiator grilles, fuel tanks and engine parts. The material selection for a particular application will depend primarily on the ability to meet the required specification and also on polymer price and total systems cost. The total systems cost includes the cost of the polymer, processing cost and tooling and assembly cost, and is a prime consideration for cost-conscious car manufacturers. Future trends in the use of plastics for automotive applications will be influenced by a number of important factors. Cost and weight reduction will remain an important driver for the motor manufacturers, which will favour plastic instead of metal. Environmental considerations will play an increasingly important role in terms of emission standards and the need to increase plastics recycling from end-of-life vehicles. Finally, there will be increasing demand for higher quality materials and greater use of safety and comfort features in the average car. 5.2 Future Prospects for the World Automotive Industry World vehicle production declined in both 2001 and 2002, and the prospects for a recovery during 2003 are very uncertain. According to the International Organisation for Motor Vehicle Manufacturers (OICA), total world production of motor vehicles declined by 3.8% in 2001 to 56.0 million units, compared to record production of 58.3 million units in the previous year. Table 5.1 shows world motor vehicle production by region for the period 1999-2001. There was wide variation in production between major world regions. The European Union and South America showed modest growth of 1% while the NAFTA region declined by 10%. In Asia, Japan and South Korea declined by 4%, while China and Thailand experienced strong growth of 13% and 12%, respectively. The emerging countries have shown significantly stronger growth than the developed countries.

In 2002, motor vehicle production showed a further sharp decline. Provisional estimates indicate that production was down by around 5%, with the steepest falls being in the three major markets of Western Europe, North America and Japan. Even the emerging markets struggled in 2002, with growth being reported only in China and Australia. For 2003, industry estimates are for a further decline in world motor vehicle production of between 2-3%. A modest recovery is predicted for the second half of the year, depending on the trends in world economic growth. Going forward, the outlook is much brighter with industry sources projecting much stronger growth from 2004 onwards. The current consensus industry projection is for average annual growth rates of 2-2.5% during the period 2005-2010. The brightest prospects for automotive growth will be Latin America, Eastern Europe and Asia, except Japan. 5.3 Future Trends for Engineering Polymers in Automotive Markets The most important factors influencing trends in use of engineering and high performance plastics in the automotive markets are discussed next.
5.3.1 Recycling of End-of-Life-Vehicles EU Directive In September 2000, the European Union issued Directive 2000/53/EC on recovery and recycling of end-of-life-vehicles (ELV). The objective of the legislation is to preserve scarce material resources by reducing the amount of waste being dumped from end-of-life vehicles into landfill sites. Under the directive, 80% of a vehicle’s weight must be recycled or reused in 2006, rising to 85% in 2015. Currently more than 75% by weight of an average car is recycled. A very high proportion of the material being recycled is metal such as sheet steel, plain steel, cast iron and aluminium. Plastics on the other hand, are not currently being recycled in large quantities from end-of-life-vehicles. It is estimated that plastics account for around 9.5% by weight of all materials used in the manufacture of vehicles. Probably just about 8% of total plastics in end-of-life-vehicles are mechanically recycled, the rest being land filled. Plastic therefore contributes less than 1% by weight of total automotive materials currently recycled. The use of plastic for manufacture of automotive parts has been growing during the last few decades. Many different types of plastic are used in hundreds of applications. These range from commodity polymers such as PVC and polyethylene to high performance engineering plastics. Furthermore, most of the high performance plastics contain a range of additives, fillers and reinforcements to enhance properties. Polymer blends such as PC/PBT and PC/ABS are also quite common in automotive applications. Both the plastics and car manufacturers face a major challenge to meet the recovery and recycling targets for plastics from end-of-life-vehicles. Not only are many different types of plastic being
56
Engineering and High Performance Plastics Market Report
used, making sorting difficult, but also plastic components are very often quite small and difficult to dismantle. Given that scale is important for economical recycling schemes, it may be difficult and costly for recyclers to gather sufficient amounts of single-plastic parts to make recycling worthwhile. Only the large and single-plastic components such as bumpers and instrument panels, which can be easily identified and dismantled, may be suitable for mechanical recycling. However, the price of virgin plastics will continue to play a vital role, as recovery of plastics in vehicles is slow and costly. If the price of virgin plastics is cheaper than recyclate, then there will not be a market for recycled materials. The amount of plastic in vehicles is forecast to grow further, hence, the pressure grows for more plastic recycling from ELVs. This is being driven by the need to reduce CO2 emissions, which means lighter vehicles and hence use of more plastics. There is however more optimism for the long-term future of recycling. Taxation on the use of landfill and the rising price of oil may force people to find alternative solutions. In response to the ELV directive, the plastic manufacturers and automotive industry joined forces in 1998 forming the European Thematic Network (ETN) for the ecologically efficient treatment of plastics in ELVs. The network looked at three ways of dealing with plastic taken from old cars: dismantling, material recycling, and shredder residue treatment and use. ETN found that market conditions remained the deciding factor in how much plastic was recovered and recycled. Recycling needs market potential and without the economics the system will completely fail. Even the Automotive Shredder Residue (ASR) working group fell across the same stumbling blocks and claimed that there was not enough high value material SR. Results for this vary greatly depending on the municipality handling the waste. This means that implementing recycling as the norm will be a tough job in the short term. Nobody thinks they should be paying for cars to be dismantled and reused. Several people in the industry believe that the end consumer should foot the bill. This type of scheme has gained acceptance in the Netherlands, where the first purchaser pays a fee when they buy, which is intended to help cover the cost of recycling. However, although this has worked well there, it may be hard to gain acceptance amongst the public in other countries. French and German plastics converters are working, separately, on a number of industry-specific solutions to conform to the EU End-of-Life-Vehicle (ELV) directive. The French plan, EDIT (Eco Design Interactive Tool) was launched in 1999 by the national association of plastics converters, Federation de la Plasturgie, in cooperation with other tier one suppliers, polymer producers and car manufacturers such as PSA and Renault. EDIT’s ‘eco-design’ project aims to develop and design new car components with very low environmental impact throughout the product’s life cycle. It provides the automotive industry with precise information on the polymer content of a plastic automotive component so that it will be better able to anticipate the materials’ impact on the environment during processing, during the component’s life, as well as at the end of its life, when recycling is called for. The first tool to be developed is a centralised database, SIGMA, which records polymer content and additives authorised or banned by the EU, as well as heavy metals. In Germany, car manufacturers such as Audi, BMW, DaimlerChrysler, Ford, Opel, Porsche and VW, have committed themselves to recycling 95% of vehicle weight by the year 2015. As the industry association Verband der Automobilindustrie (VDA) is aware that some substances in automotive materials present environmental risks through vehicle use, disposal and/or recycling, it has commissioned EDS to develop a software solution to simplify recycling. Other European carmakers, including Volvo, are also cooperating, and participation by the US industry is being discussed. There are differences between the French and German projects. While French plastics converters for data bank purposes require polymer producers to declare 90% of their materials’ composition,
57
Engineering and High Performance Plastics Market Report
the German automotive industry asks that 100% of polymer composition be recorded in the IMDS data base. The EDIT programme offers a good basis for negotiations between plastics converters and car manufacturers, Tier one suppliers can be equipped with tools that allow them to improve the environmental impact of the car component as early as the design phase. As both the French and the German projects have a European focus, teams from the two countries have been meeting in Brussels with the Association of Plastics Manufacturers in Europe (APME) to work on bringing the two databases closer together. The EDIT programme has already anticipated international requirements. It will add filters to its SIGMA data to detect whether any of the substances contained in the material will make the component fail to meet national or international regulations and/or car manufacturers requirements in worldwide markets. The French project team is developing an additional tool that would enable tier one suppliers to draw up end-of-life scenarios. They could then anticipate whether the material would lend itself to mechanical recycling or whether incineration for energy recovery would be preferable.
5.3.2 Proposed EU Legislation to Reduce Fuel Emissions Forthcoming EU environmental legislation aimed at reducing fuel consumption and CO2 emissions will be a key factor in stimulating more use of plastic in motor vehicles. The EU has stated that by 2005 the average CO2 emissions for new cars must be 120 g/km. The automotive industry has countered with an offer of 140 g/km by 2008, with a further reduction by 2011. The automotive industry claims that they will need to improve fuel economy by 25-40% to meet these suggested targets. It has also been estimated that if car engines remain unchanged, then average vehicle weight will have to be reduced by 300 kg to meet the CO2 targets. At the same time vehicle weight is increasing by 15 kg per year as more features are added. This factor alone will pave the way for use of more plastics to keep average weight lower.
5.3.3 Development of ‘Mono-Material Systems’ Producers of automotive components are seeking to reduce costs by switching to simpler processes and creating higher added value through weight reduction and use of more effective materials. Reflecting the growing importance of recycling, many OEMs are demanding the use of only one polymer or material for car interior applications such as instrument panels, and car sub-modules. Many industry insiders are convinced that future instrument panels will be based on a singlepolymer system with polypropylene being the favoured base polymer. Leading compounder A. Schulman, USA, is a strong advocate of ‘mono-material’ schemes for an all-polyolefin interior, so that automotive recyclers could easily separate out large pieces of one family of resins for recycling. In May 2001, the company received approval from General Motors for its ‘Invision’ soft-touch polyolefin materials. Schulman is marketing this high-performance alternative to PVC for a wide variety of car interior components. The company claims these products would address market demand for PVC-free parts that are soft and leather-like in texture without sacrificing scratch resistance, weatherability, colourability and moisture resistance. 5.4 Polyamide
5.4.1 Consumption Trends Automotive is the largest market sector for polyamide accounting for 34% of world market volume in 2002. Polyamide has successfully and continually replaced metal parts in many different automotive applications over the last few decades. The main reasons for the success of polyamide in automotive applications is its lower weight, lower cost and better functionality than competing
58
Engineering and High Performance Plastics Market Report
materials. The share of polyamide in motor vehicle construction will increase in future as new applications continue to be developed. Table 5.2 shows polyamide consumption in automotive applications by world region for the period 1999-2002. Table 5.2 Polyamide consumption in automotive applications by world region for the period 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 220 240 225 235 North America 229 240 216 222 Japan 58 61 54 55 Rest of Asia Pacific 86 95 93 100 Rest of World 45 50 46 48 638 686 634 660
In 2002, total polyamide consumption in automotive applications was 660,000 tonnes against 638,000 tonnes in 1999. Market tonnage declined in 2001 due to the contraction in world automotive production, but then recovered in 2002, particularly in Western Europe. North American consumption of polyamide fell sharpest in 2001, as car production was down by around 15%. Table 5.3 shows percentage share of polyamide in automotive applications by world region for the period 1999-2002. Table 5.3 Percentage share of polyamide in automotive applications by world region for the period 1999-2002 1999 2000 2001 2002 Western Europe 34% 35% 35% 36% North America 36% 35% 34% 34% Japan 9% 9% 9% 8% Rest of Asia Pacific 13% 14% 15% 15% Rest of World 7% 7% 7% 7%
In 2002, Western Europe is the largest user of polyamide in automotive, accounting for 36% of total consumption. North America is the second largest market with 34%, followed by ‘Rest of Asia Pacific’ with 15% and Japan with 8%. The share of China and other Pacific Rim countries is growing and is forecast to increase further in future because of the trend for car manufacturers to relocate production to lower cost economies.
5.4.2 Current Applications Polyamide is used in all of the main automotive application areas. Under-the-bonnet applications is by far the largest area of application followed by electrical and lighting systems, exterior and interior applications. The main under-the-bonnet applications for polyamide include the air intake manifold, the air and cooling systems, peripherals, throttle body housing, the cylinder head cover, the water-glycol circuit and engine parts. High performance PA is also used to make tubing for under-the-bonnet applications such as fuel systems.
59
Engineering and High Performance Plastics Market Report
It is estimated that the polyamide market penetration rate in air intake manifolds was 65% in 2000. This is forecast to increase to around 85% by 2005. Material suppliers are continuing to develop grades with improved hydrolysis resistance, which enables them to withstand continuous contact with hot water and glycols. Polyamide plays a major role in all the electrical and electronic equipment used in cars. It is found in the peripherals, sensors, switches, relays and electronic housing. The main applications of polyamide in the automotive exterior parts sector are rear mirror housing, door handles, windscreen wiper parts, sun roof frames, lock covers, wheel trims, fuel filler caps, painted parts such as wheel trims, and skirts and grilles. Polyamide is not yet used on its own for manufacture of body parts but can be used in combination with other polymers. It is also beginning to be used in manufacture of modular front-end carriers using the Bayer hybrid technology. In car interiors, the main applications are door handles, key lock systems, internal rear mirror, push buttons, switch control panels, steering lock casings, speedometer casings, arm rests, back-lit heater control panels, back light indicators and ashtrays.
5.4.3 Market Trends The key trends influencing further use of polyamide in automotive applications are discussed next.
5.4.3.1 Inter-Polymer Substitution Polyamide is being threatened by polypropylene in a number of automotive applications. High performance grades of polypropylene are taking share from PA in engine covers and air intake manifolds. This trend is due to better properties and the lower price of polypropylene compared with polyamide. Furthermore, polypropylene has better sound dampening properties than polyamide and can reduce sound by 5 db compared with PA, which is a major advantage for PP in electrical applications. Polyamide is also being challenged by metallocene catalyst polypropylene in climate control units and air filtration applications.
5.4.3.2 Competition from Metal Metal replacement has been a main driver for the use of polyamide in automotive applications in the past. Most of the obvious replacement of metal by PA has already taken place in the car interior, exterior and electrical systems areas. Under-the-bonnet applications however still offer some scope for further penetration by polyamide, particularly for high-performance grades. Polyamide for instance has been replacing metal in manufacture of the air inlet manifold for a number of years. Industry estimates are for PA to achieve market penetration in Europe of 85% by 2005. Levels in NAFTA and Japan are expected to be somewhat lower, but growth rates there somewhat higher. Global production of inlet manifolds made of polyamide reached 18 million in 2001. Metal may, however, come back to threaten plastic because of the trend towards high-powered small volume engines which generate a lot of heat per unit volume, and from higher emission standards. There is some re-substitution taking place with plastics being replaced by steel for some under-thebonnet parts. Steel-makers are improving their products to make thinner and lighter steel sheet with even higher tensile strength steel.
60
Engineering and High Performance Plastics Market Report
Magnesium may also come back to challenge plastic in the medium to longer term. Additional capacity due on-stream over the next five years will exert a downward movement in magnesium prices, which will make magnesium more competitive with plastics. Magnesium has only a slightly higher density than plastic, but better properties and hence the weight advantage of plastic is quite low. Magnesium can also withstand higher temperatures than plastic. The battle over the next 5-10 years will be between magnesium alloys and plastic.
5.4.3.3 Developments in Processing Technology The further development of moulding technology will benefit the use of plastic in the passenger car. For example, fusible core technology has made rapid progress, with major investment by leading moulders throughout Europe. The commercial adoption of air inlet manifolds moulded by this route for the Ford Mondeo, the Citroen Xantia, and other new model introductions, is stimulating substantial new demand, principally for glass fibre reinforced, heat stabilised polyamide 66 compounds. Friction welding of separately moulded individual components and blow moulding of high molecular weight natural and glass-reinforced polymers are also opening up new opportunities. Developments in blow moulding include process variants such as suction blow moulding. EMSGrivory has developed the Ecosys process for extending three-layer, semi-flexible water pipes for engine cooling systems. They have a PA12 resin layer and an inner layer made of a polyolefin compound, bonded by a tie layer.
5.4.3.4 Development of Hybrid Technology Bayer achieved a breakthrough in 1996 with the development of hybrid technology in structural components. The hybrid technology binding plastics and steel lowers weight and also lowers module costs and creates a high load-bearing capacity while allowing high energy absorption. A steel and PA6 glass-reinforced instrument panel developed by the team Bayer-General MotorsFisher Guide has entered series production in the US. The technology is also used in components for doors, seats, front ends and bumper brackets.
5.4.3.5 Development of In-Mould Painting Systems In-mould painting is a new technology, which will underpin the use of polyamide for car component manufacture in the coming years. The process is a variant of sandwich moulding, producing parts with a thermoplastic core fully encased within a polymer-based paint. To date, it has been proven with PP and polyamides. Advantages to processing companies include the elimination of conventional paint lines. This saves capital costs and avoids the component handling necessary prior to painting. The paint, based on powder coating technology, is supplied as a granular solid. It is fed into one barrel of a two-component injection moulding machine and, when heated, passes through a pseudo-thermoplastic phase to soften and flow. After moulding it hardens and crosslinks. Weld lines are not an issue with solid colours, but further work is needed before metallic colours can be used.
5.4.3.6 Development of the 42-Volt Electrical System The number of electrically operated systems in vehicles has risen rapidly over the past few years and the 12- and 14-volt systems currently in use will be approaching their limits. With additional electrical systems such as access to the Internet, air-conditioning, ABS, heatable rear windows, door-locking systems, electric seat adjustment and on-board computers, then the 42-volt systems currently available in prototype form will be an absolute necessity.
61
Engineering and High Performance Plastics Market Report
In terms of electrical properties and heat resistance, the components used for 42-volt electric circuits will need to satisfy more stringent demands than the 12- or 14-volt systems. The conventional fuse housings in polyether sulfone or polysulfone polymers will not withstand a 42volt fuse blowing without suffering damage. On prototype systems, these housings have been injection moulded in a new translucent grade of DuPont’s Zytel polyamide, which has fulfilled the vehicle manufacturers’ requirements. The automotive industry is reckoning on the 42-volt systems being definitively introduced in 2007. Individual car models will be equipped with these systems beforehand, however, and possibly even with two systems in parallel.
5.4.3.7 New Applications Development BASF AG and the French automotive supplier MGI Coutier S.A. have manufactured throttle systems of glass fibre-reinforced polyamide. Coutier, as a tier-one supplier, is a direct supplier to Renault, PSA, Ford, VW, GM and Fiat. In 2002, Delphi Automotive has introduced an innovative air suspension module, which is used in Land Rover’s new Range Rover, which relies on an air spring damper strut. The front module incorporates a complex piston, which is made from DuPont’s Zytel polyamide. The material is a 35% glass reinforced grade, which combines high temperature resistance with high burst and compressive pressure strength. 5.5 Acrylonitrile-Butadiene-Styrene (ABS)
5.5.1 Consumption Trends In 2002, the automotive market accounted for around a quarter of total ABS consumption. The ABS automotive applications market has been growing more slowly in recent years, particularly in the more developed regions such as Western Europe and North America. This trend is due to growing competition from other polymers such as polypropylene and unsaturated polyesters. ABS has however benefited from developments of continuous mass processing technology, which has meant enhanced colour consistency and eliminated the need for painting. The process produces low-gloss products, a desirable feature for applications in the automotive sector. Table 5.4 shows ABS consumption in automotive applications by world region for the period 19992002. Table 5.4 ABS consumption in automotive applications by world region for the period 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 180 194 184 186 North America 385 410 390 394 Japan 61 63 56 58 Rest of Asia Pacific 440 490 475 515 TOTAL 1066 1157 1105 1153
In 2002, total ABS consumption in automotive applications was 1,153,000 tonnes compared with 1,066,000 tonnes in 1999. Volumes declined in 2001 due to the major contraction in world automotive production, but have since recovered in 2002. Table 5.5 shows percentage share of ABS in automotive applications by world region for the period 1999-2002.

Asia, including Japan, is by far the largest user of ABS in automotive, accounting for 50% of total consumption in 2002. North America is the second largest market with 34%, followed by Western Europe with 16%. The share of China and other Pacific Rim countries is growing fast and is forecast to increase further in future because of the trend for car manufacturers to relocate production to lower cost economies.
5.5.2 Current Applications Interior parts are the largest area of application for ABS in the automotive market accounting for around 60% of total market volume. The main applications are instrument panels, loudspeaker grilles, door handles, door trim, glove box compartment lids and centre consoles. PC/ABS blends are also used in many of these applications, mainly in higher value cars. Exterior parts account for just over a quarter of the total volume of ABS used in the automotive market. The principal applications are wheel trim, mirror and light housings. ABS can also be found, usually in combination with polycarbonate as a blend, in electrical systems housing. The material is rarely found in under-the-bonnet applications because of its lower temperature resistance compared with other polymers. ABS is also used in combination with polycarbonate for electrical parts such as navigation systems housing. PC/ABS is considered to have good growth prospects in navigation systems housing. A small amount of ABS is used in under-the-bonnet applications.
5.5.3 Market Trends The key trends influencing further use of ABS in automotive applications are discussed next.
5.5.3.1 Replacement of Traditional Materials The potential use of ABS both inside and outside the car has almost reached saturation as the material has almost completely replaced die-cast metal in key applications such as light and mirror surrounds. PC/ABS blends however remain a popular choice for instrument panels in some luxury models and demand will continue to grow. PC/ABS should also see good growth prospects in navigation systems housing.
5.5.3.2 Inter-Polymer Substitution ABS is not expected to displace many other types of plastics in automotive applications in future. There is however a possibility that PC/ABS blends may be one of the candidates being considered by OEMs to replace styrene-maleic anhydride copolymer (SMA) in some interior applications. Manufacturers are known to be looking for alternatives to SMA copolymer. There is a stronger possibility of ABS being challenged by other plastics such as polypropylene. Future trends within the car interior are likely to see the increasing development of one-material
63
Engineering and High Performance Plastics Market Report
solutions for integrated components to facilitate assembly and recycling. Within dashboards there is a move towards softer materials as the standards found in larger luxury models are increasingly demanded for smaller models. Improving grades of unfilled PP are expected to continue taking market share from ABS in interior panels on the grounds of weight and cost. BASF has introduced an improved polystyrene grade that could provide low-cost competition for ABS products. The PS ‘495 F’ is noted for its outstanding toughness and flowability, as well as for high rigidity and good heat resistance. It can be used to produce big parts with a complex geometry and a low wall thickness. The company claims that the notched impact strength has been improved by 60%, and thus raised to the level of standard ABS grades. Many applications that require ABS today could also be implemented in PS ‘495 F’. 5.6 Polybutylene Terephthalate (PBT)
5.6.1 Consumption Trends Automotive is the largest market for PBT with 41% of total world market volume in 2002. PBT has experienced strong growth in automotive markets in recent years. It is finding increasing use, for instance, in headlight frames, windscreen wipers, central-locking housings and electrically operated windows. Table 5.6 shows PBT consumption in automotive applications by world region for the period 19992002. Table 5.6 PBT consumption in automotive applications by world region for the period 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 40 45 45 47 North America 75 80 73 75 Japan 30 33 31 32 Rest of Asia Pacific 33 38 36 38 Rest of World 3 4 3 4 TOTAL 181 200 188 196
In 2002, total PBT consumption in automotive applications was 196,000 tonnes compared with 181,000 tonnes in 1999. Volumes declined in 2001 to 188,000 tonnes due to the downturn in world automotive production, but showed a modest increase in 2002.

Engineering and High Performance Plastics Market Report
downturn in US car production after 2000, and the greater market maturity of many PBT automotive applications. Western Europe is the second largest market with 24%, followed by ‘Rest of Asia Pacific’ with 20% and Japan with 16%. Western Europe has grown its share of total consumption in recent years due largely to new applications for PBT and a lower decline in car production than in the USA. The share of China and other Pacific Rim countries is growing fast and is forecast to increase further in future.
5.6.2 Current Applications Electronic components and housings is the main applications area for PBT in the automotive sector accounting for over 60% of total volume. Exterior applications are the next most important market, followed by interior applications. PBT has only limited use in under-the-bonnet applications. PBT has been replacing metal in automotive electrical components where its high stiffness and strength combined with good heat ageing performance are particularly valuable. Resistance to fuels and lubricants is also vital here. Glass fibre-reinforced grades made from PBT also have especially low warpage. In addition, PBT has excellent electrical and thermal long-term performance. The low flammability of flame retardant grades is an added advantage. Applications include electric motor covers, gear housings, fuel boxes and relays, sensors, lamp reflector body and brackets, connectors, ignition coils and bobbins and brake booster valve bodies. The main applications for PBT in the car interior include parts of the instrument panel such as ashtrays and other interior trim. For exterior applications PC/PBT blends are used mainly in the manufacture of automotive bumper fascia. Other uses for PBT include windscreen wiper arms, mudguards, mirror housings and door handles. PBT is used in applications where a high quality, weather resistant surface is a key requirement for components. Under-the-bonnet applications is the smallest area of application for PBT in automotive. Typical applications include parts for the carburettor.
5.6.3 Market Trends The key trends influencing further use of PBT in automotive applications are discussed next.
5.6.3.1 Growth in Electrical Applications The amount of electrical and electronics components in cars is growing and will continue to grow during the forecast period as manufacturers build-in greater safety and comfort features into their cars. PBT is the major polymer for these applications and is well placed to take advantage of the trend. Another important trend encouraging further growth for PBT in electrical systems will be the development of modular sub-assemblies, incorporating electrical and electronic parts.
5.6.3.2 Replacement of Metal Parts PBT has been replacing metals in automotive applications, because of its high stiffness and strength, good heat ageing performance and resistance to fuels and lubricants. Metal replacement will not however, be as much an influence on PBT demand in future because most of the potential replacement has already taken place.

5.6.3.3 Inter-Polymer Substitution PBT has been replacing polyamide in some new models in electrical switches, connectors and motor housings because of its better dimensional stability. OEMs are also becoming more demanding in applications such as window lift motor housing. There is a small threat from polypropylene in some interior applications. Polypropylene has a cost advantage in some areas, and PBT’s key properties of strength, low water absorption, temperature and chemical resistance, are not often required for interior applications.
5.6.3.4 New Product Development Bayer has introduced a new grade of Pocan, a hydrolysis-resistant grade of PBT, specifically for connectors used in automotive production. The new grade was developed in cooperation with the Nuremberg-based subsidiary of FCI Automotive, a leading manufacturer of connectors. Bayer claims that the new product is able to satisfy the extreme demands placed on the ageing resistance of such components. It adds that using the new material will help carmakers reduce costs by eliminating the need for expensive, highly heat-resistant speciality polymers especially for airbags. In airbags and belt tensioning systems, these connectors link the ignition unit to the control system and power supply. 5.7 Polycarbonate (PC)
5.7.1 Consumption Trends Automotive accounts for 17% of total world polycarbonate market volumes in 2002. Polycarbonate has achieved good growth in automotive applications in recent years, mainly by replacement of glass headlamp lenses, but also in car interior applications. Polycarbonate has however almost fully penetrated all possible car interior applications and about 85% of all car headlamp lenses are now produced using polycarbonate. Exterior trim and bumper fascia markets are also reaching saturation. Hence, future growth potential from traditional applications will be restricted. Developments in the use of polycarbonate for automotive glazing, which is currently being commercialised, may lead to a substantial increase in demand for the material in future. Table 5.8 shows polycarbonate consumption in automotive applications by world region for the period 1999-2002. Table 5.8 Polycarbonate consumption in automotive applications by world region for the period 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 55 59 48 51 North America 120 130 100 104 Japan 25 27 20 21 Rest of Asia Pacific 85 92 95 100 Rest of World 5 6 6 7 TOTAL 290 314 269 283
In 2002, total polycarbonate consumption in automotive applications was 283,000 tonnes against 290,000 tonnes in 1999. Volumes declined sharply in 2001 to 269,000 tonnes due to the downturn in world automotive production. In 2001, North American polycarbonate sales volume fell by 30,000 tonnes to 100,000 tonnes. Total world consumption of polycarbonate in automotive applications remains below 1999 levels, despite a modest pick up in volumes during 2002.

Table 5.9 shows percentage share of polycarbonate in automotive applications by world region for the period 1999-2002. Table 5.9 Percentage share of polycarbonate in automotive applications by world region for the period 1999-2002 1999 2000 2001 2002 Western Europe 19% 19% 18% 18% North America 41% 41% 37% 37% Japan 9% 9% 7% 7% Rest of Asia Pacific 29% 29% 35% 36% Rest of World 2% 2% 2% 2%
North America is the largest user of polycarbonate in automotive, accounting for 37% of total consumption in 2002. The share of North America has however been declining since 1999, due mainly to the sharper downturn in US car production after 2000, and the greater market maturity of many polycarbonate automotive applications. The ‘Rest of Asia Pacific’ is the second largest market with 36%, followed by Western Europe with 18% and Japan with 7%. As in many other polymer classes, the share of China and other Pacific Rim countries is growing fast and is forecast to increase further in future because of the trend for car manufacturers to relocate production to lower cost economies. On the other hand, the shares of North America and Japan have fallen significantly in the last three years.
5.7.2 Current Applications Polycarbonate is used mainly for manufacture of car light lenses. Glass car headlight lenses have been virtually replaced by transparent plastics. Plastic can resist high levels of heat, are shatterresistant and can be moulded into almost any shape. Plastics’ versatility also gives the automotive engineer greater freedom for design and placement of car headlights. The main applications for polycarbonate in the car interior are lenses for instrument panel displays and ceiling lights. Typical applications for PC/ABS in the car interior are instrument panels where fast cycle times are desired and interior components where impact strength, dimensional stability and high heat performance are required. PC/ABS is also used in many other small application areas such as door handles, loudspeaker grilles, B-post finishes, navigation systems housing and interior trim. A small amount of PC/PBT is used inside the car, mainly for the manufacture of interior trim. Pure polycarbonate resin is rarely used for exterior body parts. However, PC/ABS is used for manufacture of applications such as mirror housings, light housings and wheel trim. PC/PBT is found almost entirely in exterior applications, the most notable applications being bumper fascias and also body panels. The body panels of the Smart Car for example, are made from PC/PBT blends. PC/PBT blends account for only 5% of the global bumper fascia market.
5.7.3 Market Trends The key trends influencing further use of polycarbonate in automotive applications are discussed next.
5.7.3.1 Development of Automotive Glazing In mid 1997, Exatec GmbH & Co., a 50-50 joint venture involving Bayer AG and GE Plastics was established to develop hard-coated polycarbonates for glass replacement in vehicles. It is claimed that PC windows can give a weight saving of around 40% compared with glass. Product and systems development is concentrating mainly on the rear and side windows, with the project 67
Engineering and High Performance Plastics Market Report
consisting of three different stages. Starting with the creation of a basic substitute for glass, the next stage is to develop windows with integrated functions and moulded-on connections. Finally, the aim is to produce complete body panels, in which not only transparent areas of PC, but also other elements such as ventilator grilles, lamp housings and wheel-arch covers can be integrated by multi-component injection moulding.
5.7.3.2 Replacement of Glass Lenses Polycarbonate has been replacing glass headlamp lenses over many years, and has now achieved a high rate of market penetration. Polycarbonate lenses make a saving of up to 1 kg in weight compared to glass, Polycarbonate lenses give much greater freedom for improvement of optical efficiency and they can be recycled. The high penetration rate in car headlamp lenses will however imply lower growth for PC in future. The use of polycarbonate in automotive sidelights however is seen as a potential growth market.
5.7.3.3 Inter-Polymer Substitution PMMA is the main competitor to polycarbonate in automotive lighting applications. Polycarbonate carries a price differential compared to PMMA, and when this narrows there is a tendency for s small amount of switching to occur. PC/ABS remains a popular choice for manufacture of instrument panels, particularly for top of the range vehicles. OEMs are also starting to use more PC/ABS for middle of the range car instrument panels because of its better quality compared with other polymers such as polypropylene. There is also a possibility that PC/ABS blends may be one of the candidates being considered by OEMs to replace SMA in some interior applications. Manufacturers are known to be looking for alternatives to SMA copolymers. While PC/ABS continues to perform well for instrument panels, there is still a threat being posed by long glass fibre-reinforced polypropylene. High temperature PMMA also poses a threat to some small polycarbonate applications inside the car and may be a threat for inner headlamp lenses in a few years time. Finally, Noryl PPO/PA blends are challenging PC/PBT in bumper fascia applications for mid to top of the range vehicles. 5.8 Polyoxymethylene (POM)
5.8.1 Consumption Trends Automotive is the largest market for POM, representing 32% of total world volume in 2002. The polyacetal content in passenger cars has been increasing steadily during the last couple of decades but is now slowing down due to growing competition from other polymers and market maturity of key applications. The development of new products and technologies will however mean that use of POM in the car will continue to grow in future. Table 5.10 shows POM consumption in automotive applications by world region for the period 1999-2002. In 2002, total POM consumption in automotive applications was 192,000 tonnes against 183,000 tonnes in 1999. Volumes declined in 2001 to 189,000 tonnes due to the downturn in world automotive production. In 2002, there was a modest pick up in sales volumes.

Western Europe and ‘Rest of Asia Pacific’ are the largest users of POM in automotive, each accounting for 34% of total consumption in 2002. North America is the second largest consumer with 21% of total consumption, followed by Japan with 11%. The shares of both North America and Japan have been declining since 1999. North America’s share has fallen mainly due to the sharp downturn in US car production after 2000, and the greater market maturity of many POM automotive applications. Japan has also seen a sharp fall in car production and a growing trend for car manufactures to produce offshore. The ‘Rest of Asia Pacific’ has benefited from these trends, and will continue to account for a growing market share.
5.8.2 Current Applications Electrical and lighting hardware systems are the largest area of application for POM in automotive markets accounting for 40% of total market tonnage. Interior parts is the second largest area with 35%, followed by under-the-bonnet parts with 15%, and exterior parts with 10%. Some of the main applications for POM in electrical systems include mountings and brackets for lamp reflectors, gear trains for helical window lift gears, interior input control switches such as multi-function turn signal switches and master light control units, seat adjustment systems, climate control systems and door lock systems. Polyacetals are particularly valued in these applications for their chemical and high temperature resistance, dimensional stability and low wear and friction (gear trains). Interior applications is the second biggest area of application for POM in automotive. In the car interior applications market, acetal is mainly used for door handles, lock mechanisms, loudspeaker grilles, parts for safety systems, sun roof systems, fasteners, manual window systems and seat release buttons. Under-the-bonnet applications for POM include the fuel delivery module and brake systems. They are valued for their outstanding fuel resistance, dimensional stability, reduced swelling and improved fatigue and creep resistance. The main applications for POM in car exteriors are windscreen wipers and door handles.

5.8.3 Market Trends The key trends influencing further use of POM in automotive applications are discussed next.
5.8.3.1 Inter-Polymer Substitution The growth in use of polyacetals for automotive applications has been much more influenced by its replacement of metal rather than other polymers. There is a potential threat to polyacetals from polyamide. Some OEMs may be encouraged to switch from POM to polyamide for interior applications such as instrument panels, grilles and switches, because of the higher formaldehyde emissions from POM.
5.8.3.2 Product Developments The introduction of better products is creating more opportunities for POM in the automotive market. A new line of UV-stabilised soot-pigmented POM produced by Ticona, for example, is claimed to be more resistant to UV rays due to a better light blocking system. The new materials, which Ticona recommends for windscreen wiper and fuel tank covers, among other applications, use a combination of UV absorbers and free radicals that the company says ensures far less colour differentiation. Ticona has also recently launched an odour-free product, which it is hoped will persuade OEMs to continue using polyacetals for car interior applications.
5.8.3.3 Technology Development The development of outsert technology (metal-plastic composites) offers good growth potential for POM in automotive applications. Another forward-looking application being developed is the combination of POM with injection moulded ‘soft’ components, including NBR rubber and polyester elastomers.
5.8.3.4 Growth in Electrical Systems More electrical systems are being incorporated into each new generation of motor vehicle to ensure greater passenger comfort and safety. These include automatic window systems, electronic seat adjustment, climate control systems, navigation systems and in-car entertainment. Electrical systems make extensive use of POM.
5.8.3.5 Replacement of Metal Metal replacement has been a key driver of demand for polyacetal in automotive applications. Most of the potential replacement has however already occurred and so replacement of traditional materials will be a lower influence on future growth trends. 5.9 Polymethyl Methacrylate (PMMA)
5.9.1 Consumption Trends Automotive accounts for 15% of total PMMA world market volume in 2002. Acrylics have almost fully penetrated all potential glass replacement applications both inside and outside the car, especially in North America and Western Europe. There is however better growth potential in Asia.

Table 5.12 shows PMMA consumption in automotive applications by world region for the period 1999-2002. Table 5.12 PMMA consumption in automotive applications by world region for the period 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 40 44 39 43 North America 63 67 63 65 Japan 21 21 18 18 Rest of Asia Pacific 13 15 16 18 TOTAL 137 147 136 144
In 2002, total world consumption of PMMA in automotive applications was 144,000 tonnes against 137,000 tonnes in 1999. Along with other engineering plastics, PMMA volumes declined in 2001 to reach 136,000 tonnes due to the downturn in world automotive production. In 2002, market volumes recovered slightly, but are still below 2000 levels. Table 5.13 shows percentage share of PMMA in automotive applications by world region for the period 1999-2002. Table 5.13 Percentage share of PMMA in automotive applications by world region for the period 1999-2002 1999 2000 2001 2002 Western Europe 29% 30% 29% 30% North America 46% 46% 46% 45% Japan 15% 14% 13% 12% Rest of Asia Pacific 9% 10% 12% 13%
North America is the largest user of PMMA in automotive accounting for 45% of total consumption in 2002. Western Europe is the second largest consumer with 30% of total consumption, followed by ‘Rest of Asia Pacific’ with 13% and Japan with 12% of total world consumption. Once again, the most interesting feature of world consumption patterns is the declining share of Japan and the sharp increase in ‘Rest of Asia Pacific’ region. This is mainly attributable to the trend for car manufactures to produce offshore in other Asian countries to reduce their costs.
5.9.2 Current Applications Electrical and lighting systems are the largest application area for PMMA in the automotive market accounting for two-thirds of total market tonnage. Interior parts account for the remaining third of market tonnage. Acrylics are used mainly as a glass replacement material in automotive lighting systems. Automotive lighting systems includes car headlights, brake lights, indicator lights, back-up lights and fog lights. These lenses are mostly made from polycarbonate, and to a lesser extent, acrylics. Acrylics are used mainly to manufacture lenses for rear lights, indicator lights and brake lights. They cannot be used for manufacture of inner or outer headlamp lenses, where the temperature requirements are too high. The main automotive interior applications for PMMA include dashboard dial covers, dashboard lights, ceiling light covers and emblem covers. Glass car headlight lenses have been virtually replaced by transparent plastics. These plastics can resist high levels of heat, are also shatter-resistant and can be moulded into almost any shape.
71
Engineering and High Performance Plastics Market Report
Plastics’ versatility gives the automotive engineer greater freedom for design and placement of car headlights.
5.9.3 Market Trends The key trends influencing further use of PMMA in automotive applications are discussed next.
5.9.3.1 Replacement of Glass Car Headlamp Lenses Glass replacement for headlamp lenses has been the key driver of acrylics in automotive applications. The glass replacement market both inside and outside the car is however almost fully penetrated, which restricts future growth potential. On the other hand, the headlamps and rear lights on new cars are getting bigger for design and safety reasons. Hence, the amount of polymer required per headlamp is increasing. Major changes are imminent in both headlamp and rear light systems with the incorporation of plastics-based LED (Light Emitting Diode) brake-light systems and ‘light box’ systems, whereby an easily accessible single light source is used to provide exterior lighting for the car via acrylic fibre-optic wires. The incorporation of a ‘light box’ will eliminate the need for high heat resistant plastics in automotive lighting systems, allowing substitution for even lighter plastic lenses that retain their ability to resist impacts.
5.9.3.2 New Applications Development The number of dials and displays on the car instrument panels is growing due to incorporation of additional safety and comfort features in more new cars. This is raising demand for PMMA for manufacture of dial and light covers.
5.9.3.3 Inter-Polymer Substitution Acrylics will continue to challenge polycarbonate in glass replacement applications. There may be a possibility that higher temperature resistant acrylics could challenge polycarbonate for inner headlamp lenses in future. There is also a small chance that acrylics may be used by some OEMs instead of other plastics such as ABS for B-posts. 5.10 Polyphenylene Oxide (Ether) Blends (PPO and PPE)
5.10.1 Consumption Trends Automotive is by far the largest market for PPO/PPE blends, representing 52% of total world volume in 2002. Automotive is a growing market for PPO/PPE blends, with particularly good prospects for exterior, and to a lesser extent, interior applications. Some of the major suppliers, most notably GE Plastics, are very active in promoting the use of their Noryl product range and have developed new and improved grades in recent years. Table 5.14 shows PPO/PPE blends consumption in automotive applications by world region for the period 1999-2002. In 2002, total PPO/PPE blend consumption in automotive applications was 185,000 tonnes compared with 180,000 tonnes in 1999. Volumes declined in 2001 to 181,000 tonnes due to the downturn in world automotive production. There was a modest recovery in sales volumes during 2002.

North America is by far the largest consumer of PPO/PPE blends in automotive, accounting for 54% of total consumption in 2002. Western Europe is the second largest consumer with 25% of total consumption, followed by Japan with 21%. The shares of all major regions have remained fairly stable during the last four years.
5.10.2 Current Applications Modified PPO/PPE blends are used in a wide range of demanding automotive applications as replacement for metal and thermosets. Exterior parts are the largest application area for PPO/PPE blends accounting for 45% of total market tonnage. Interior parts are the second largest area with 30%, with under-the-bonnet applications representing 15% and electrical systems 10% of market tonnage. The main applications are described below. •
Bumpers and fascias – The materials have excellent low temperature impact after painting. High modulus (typically 30-50% greater than TPO) and high heat resistance enable thinner walls for lighter weight and reduced cycle times.
•
Front-end modules – PPO blends have high elongation, low specific gravity and long-term heat resistance.
•
Instrument panels – Main benefits are strong chemical and impact resistance.
•
Under-the-bonnet components – Main features of PPO/PPE blends are chemical resistance, impact resistance and vibration dampening, plus good sound/vibration dampening and resistance to the temperature and moisture extremes typically found under the hood.
•
Grille opening reinforcements – GE Plastics NORYL PPX resins are a popular choice for this application, which requires materials that are tough and dimensionally stable for component system performance, and also moisture, heat and vibration resistant.
5.10.3 Market Trends The key trends influencing further use of PPO/PPE in automotive applications are discussed next. 73
Engineering and High Performance Plastics Market Report
5.10.3.1 Inter-Polymer Substitution The better heat resistance and conductivity have led to replacement of other polymers by PPO/PPE in bumper systems. Also, its better heat resistance and lower odour emissions give PPO/PPE an advantage over PC/ABS for instrument panels. PPO/PPE does however face tough competition from other polymers in key application areas, and manufacturers must convince automotive designers and component manufacturers that it is a better product in terms of quality and total systems cost for it to displace other established systems. PPO/PPE blends cost two to three times more than higher end polyolefins for bumper systems. While the price of PPO blends is likely to come down gradually as production increases, high cost may deter some potential customers.
5.10.3.2 Development of New Applications PPO/PPE blends are finding new applications in the car. The Mercedes A Series for example, uses Noryl PPO/PA blends for the front mudguards. According to Mercedes, these mudguards return to their original shape after a minor accident without any repairs or a paint job being necessary. GE Plastics is also planning to develop more applications for Noryl outside the car during the next two years. The replacement of metal and polyamide for tank flaps is a potential target.
5.10.3.3 New Product Development Constant product development has been a feature in the development of the PPO/PPE product family. Higher conductivity, mineral-filled and low odour emission grades are some examples of how the product has been improved to open up new market opportunities. GE Plastics also introduced an improved, conductive version of Noryl GTX (PPO/PA blend), which dispensed with the need to prime plastic parts before painting them. By adding conductive material, it was possible to develop a thermoplastic that makes it easier to paint hard-to-reach places. 5.11 Polyphenylene Sulfide (PPS)
5.11.1 Consumption Trends Automotive is by far the largest market for PPS, representing 51% of total world volume in 2002. PPS use in automotive markets has seen strong growth in recent years due mainly to its replacement of metal, thermosets and other types of plastic, in more demanding applications. Continued good growth is expected during the next five years. Table 5.16 shows PPS consumption in automotive applications by world region for the period 1999-2002. Table 5.16 PPS consumption in automotive applications by world region for the period 19992002 (000 tonnes) 1999 2000 2001 2002 Western Europe 5 5 5 5 North America 6 7 6 7 Japan 9 10 10 10 Rest of Asia Pacific 4 5 4 5 TOTAL 25 27 25 26
In 2002, total PPS consumption in automotive applications was 26,000 tonnes compared with 25,000 tonnes in 1999. Volumes declined from 27,000 tonnes in 2000 to 25,000 tonnes in 2001 due 74
Engineering and High Performance Plastics Market Report
to the downturn in world automotive production. There was a small improvement in sales volumes in 2002. Table 5.17 shows percentage share of PPS in automotive applications by world region for the period 1999-2002. Table 5.17 Percentage share of PPS in automotive applications by world region for the period 1999-2002 1999 2000 2001 2002 Western Europe 19% 19% 19% 19% North America 26% 26% 25% 25% Japan 38% 38% 39% 38% Rest of Asia Pacific 17% 17% 17% 18%
Japan is the largest consumer of PPS for automotive, accounting for 38% of total consumption in 2002. North America is the second largest consumer with 25% of total consumption, followed by Western Europe with 19% and ‘Rest of Asia Pacific’ with 18%. The ‘Rest of Asia Pacific’ region is increasing at the fastest rate in recent years due to its growing share of automotive production.
5.11.2 Current Applications PPS is an ideal choice for automotive parts exposed to high temperatures, automotive fluids, or mechanical stress. PPS is a lighter weight alternative to metals that is resistant to corrosion by salts and all automotive fluids. The ability to mould complex parts to tight tolerances and insert moulding capability accommodate multiple component integration. Under-the-bonnet is the largest application area for PPS accounting for 70% of total market tonnage. Electrical parts account for the remaining 30%, as PPS is rarely used for manufacture of interior and exterior parts. PPS is used in the following automotive applications. •
Fuel/Induction Systems – EGR (exhaust gas recirculation) components, fuel flow sensors, fuel line connectors, fuel pump components, fuel rails, injector bobbins, throttle bodies/deactivator.
•
Coolant Systems – extension tubes, heater core tanks, thermostat housings, valve components, water inlets/outlets, water pump impellers.
•
Brake Systems – ABS brake pistons, ABS motor components, booster pistons, electric brakes, valve bodies.
•
Electrical Systems – alternator components, connectors, ignition components, motor brush cards, sensors, switches.
•
Powertrain/Transmission – engine gasket carriers, lock-up collars, seal housings, servo covers, servo pistons, shift cams/forks, stators and transmission pistons.
•
Automotive Lighting – bulb housings, reflectors, sockets.
5.11.3 Market Trends The key trends influencing further use of PPS in automotive applications are discussed next.
75
Engineering and High Performance Plastics Market Report
5.11.3.1 Replacement of Traditional Materials PPS growth has mainly come about by replacement of parts made from metal and thermosets, both under-the-bonnet and in electrical applications. While PPS may cost more than most metals and thermosets, the total production cost of PPS parts is very competitive with traditional materials, which has encouraged growth.
5.11.3.2 Inter-Polymer Substitution Increasing temperature requirements under-the-bonnet has led to PPS replacing other plastics such as polyamide. Also, the share of diesel engines is increasing which is further encouraging growth in high temperature thermoplastics such as PPS at the expense of other plastics. Polyamide and polyesters continue to challenge PPS in certain applications in which the superior performance properties of PPS are not critical. Also, the high cost of PPS compared to PBT and polyamide, means that it remains uncompetitive with these materials in many applications.
5.11.3.3 New Applications Development The US company Plastic Molding Corporation (PMC), is using the polyphenylene sulfide (PPS) from Ticona GmbH for the production of fuel pumps. The company claims that PPS achieves air chamber tolerances in production of below 0.05 mm, a figure that appeared impossible with other materials in the production of various fuel pumps. PPS is also finding new moulding applications under-the-bonnet because of its advantages and properties.
5.11.3.4 New Product Developments The new PPS grade in Ticona’s Fortron range resists aggressive media such as gasoline, diesel or liquefied natural gas when used, for example, as a barrier layer in fuel lines. Tests carried out at the US manufacturer of flexible fuel lines, Total Containment Inc., showed, among other things, that it is suitable for UL listing. 5.12 Polyetherimide (PEI)
5.12.1 Consumption Trends Automotive is by far the largest market for polyetherimide, representing 50% of total world volume in 2002. Polyetherimide usage in automotive applications has been increasing in recent years due to its replacement of metal, thermosets and bulk moulding compounds (BMC). There is still scope for further use of PEI in car electrical and under-the-bonnet applications, which will underpin good growth prospects. Table 5.18 shows polyetherimide consumption in automotive applications by world region for the period 1999-2002. Total polyetherimide consumption in automotive applications was 7,000 tonnes in 2002. Demand for PEI was increasing up to 2001 when consumption fell due to the downturn in world automotive production. In 2002, there was a modest recovery in sales volumes.

North America is the largest consumer of PEI for automotive, accounting for 60% of total consumption in 2002. Western Europe is the second largest consumer with 19% of total consumption, followed by ‘Rest of Asia Pacific’ with 11% and Japan with 9%.
5.12.2 Current Applications Electrical and lighting systems are the largest application area for PEI in the automotive market, accounting for 90% of total market volume. Under-the-bonnet parts account for the remaining 10% of market volume. PEI is used in applications that require a high heat resistance material, high strength, modulus and broad chemical resistance. The principal automotive applications for PEI include transmission components, throttle bodies, ignition components, thermostat housings, bezels, reflectors, lamp sockets, and electromechanical systems such as fuses, gears, bearings, solenoid bodies, ignition switches and oil pump drives. PEI is also widely used in automotive lighting applications such as headlight reflectors, fog light reflectors, bezels and light bulb sockets. PEI is selected for its high heat resistance (up to 200 °C), ability to be metallised without a primer, and its competitive systems cost versus thermosets. PEI is also widely used in the aircraft industry. Main applications include air and fuel valves, food tray containers, steering wheels, interior cladding parts and semi-structural components. PEI is selected for internal aircraft applications for its inherent flame retardancy and low smoke emissions. It also has excellent chemical resistance to fuels and fluids used in the aircraft industry.
5.12.3 Market Trends The key trends influencing further use of polyetherimide in automotive and aircraft applications are discussed next.
77
Engineering and High Performance Plastics Market Report
5.12.3.1 Replacement of Traditional Materials A key driver of PEI growth in automotive applications is replacement of metal, thermosets and bulk moulding compounds (BMC), due to its greater cost efficiency in manufacture of complex parts. The dimensional stability offered by PEI is another selling point together with its high heat performance and chemical resistance. There is still scope for further use of PEI in car electrical and under-the-bonnet applications, which will underpin its continued growth. Polyetherimide is also now being used in the headlamp systems in some US cars instead of BMC. The benefits claimed by GE Plastics for its Ultem product are greater ease of design and processing, lower scrap, simpler post-processing and melt recyclability.
5.12.3.2 Growth in Electrical Systems PEI is most often found in electrical systems, a market segment which is showing the fastest growth for plastics in the automotive industry. New and improved electrical systems are being introduced into each new generation of passenger car to give better safety and comfort features. This will continue to bolster growth in use of PEI in future.
5.12.3.3 Inter-Polymer Substitution Polyetherimide is in competition with other less expensive high performance polymers such as PSU and PES. It is however a very cost effective material and the total systems cost of using PEI compares favourably with competing materials.
5.12.3.4 Product Development Attention is focused on improving the flow of the material in order to reduce cycle times for injection moulding complex and thin-walled components. GE Plastics has found for example that the viscosity of PEI can be reduced by 50% with the addition of a small amount of PPO polymer. The mechanical properties of PEI remain constant with the addition of the PPO. There are also advantages with glass fibre-reinforced materials. For example, the typical processing temperature with 30% glass fibre-reinforced PEI (360-380 °C) blended with 21% PPO can be reduced to 310-340 °C. This flow-optimised technology can find applications in, for example, automotive headlamp reflectors, lamp bases, throttles, chip carriers and aerials. 5.13 Polysulfone (PSU), Polyethersulfone (PES)
5.13.1 Consumption Trends Automotive markets represented 20% of total world PSU/PES consumption in 2002. PSU/PES has found growing usage in automotive applications in recent years. A key driver has been replacement of metal and thermoset materials. Table 5.20 shows PSU/PES consumption in automotive applications by world region for the period 1999-2002. Total PSU/PES consumption in automotive applications was 4,500 tonnes in 2002 compared with 4,100 tonnes in 1999. Demand for PSU/PES was increasing at a fast rate up to 2001, when consumption fell due to the downturn in world automotive production. There was some recovery in sales volumes during 2002.

5.13.2 Current Applications PES and PSU are very high temperature resistant amorphous thermoplastics that are used where the performance requirements exceed the capabilities of other engineering plastics such as polyamide, PBT and polyacetals. PES and PSU can also replace thermosets, metals and ceramics. The main reasons for PES/PSU being used in automotive applications are their high stiffness, continuous operating temperatures, high mechanical strength, good electrical insulation properties, resistance to lubricants, and good dimensional stability. In the car, the main applications for PSU and PES are found under-the-bonnet such as battery caps, oil pumps, oil control pistons, transmission parts, carburettor parts, bearing cages and ignition components. PES and PSU are also found in car headlights (screens, housings and reflectors). Glass fibre-reinforced PES is also particularly well suited to engine oil circulation systems. In engine oil circulation systems glass fibre-reinforced PES is particularly suitable, since the polymer matrix ensures the necessary thermal and dimensional stability when in contact with hot engine oil. In addition there are the outstanding mechanical and tribological characteristics up to high temperatures. PES/PSU are also used for aircraft interior and exterior components.
5.13.3 Market Trends 5.13.3.1 Replacement of Thermosets The direct metallisability of injection moulded PES components using vacuum coating processes combined with increased freedom regarding the design of headlights is a great advantage over thermosets. A substantially simplified production process offsets the higher price of PES. Thus the

5.14.2 Current Applications Liquid crystal polymers have excellent dimensional stability and creep resistance, especially at very high temperatures. They are highly resistant to many chemicals, including concentrated acids, bases and hydrocarbons. They also display outstanding fatigue resistance and high dielectric strength performance over a very wide temperature range. These properties make them especially suitable for automotive ignition system components, lamp sockets, transmission system components, pump components, coil forms and sensors.

5.14.3 Market Trends 5.14.3.1 Lead-Free Soldering Methods The introduction of the lead-free soldering method has led to an increase in the temperature requirements of between 20-30 °C and thus created a demand for products with improved properties.
5.14.3.2 Material Replacement Materials that are resistant to high temperatures such as ceramics, metals and thermosets, may be driven out of their existing application areas and replaced by the more cost-efficient injection moulding process with LCP. 5.15 Polyetheretherketone (PEEK)
5.15.1 Consumption Trends Automotive is the largest market for PEEK polymers accounting for 41% of total world volume in 2002. PEEK is one of the leading high-performance plastics that are replacing metal for under-thebonnet applications. Table 5.24 shows PEEK consumption in automotive applications by world region for the period 1999-2002.

Engineering and High Performance Plastics Market Report
5.15.2 Current Applications With the trend towards higher operating temperatures and miniaturization in the engine compartment, plastics replacing metals also offer weight reduction, noise reduction and functional integration. PEEK is one of those high performance polymers that can be used in very demanding applications as a replacement for metal. The most important performance benefits of PEEK are enhanced dry and lubricated surface interaction, outstanding mechanical performance over a wide temperature range, ease of processing and excellent fatigue properties. Key automotive applications are found under-the-bonnet, including piston units, seals, washers, bearings and various active components used in applications such as transmission, braking and air-conditioning systems. In the aerospace market, PEEK polymers are replacing aluminium and other metals in a wide range of applications. The polymer combines outstanding physical and thermal characteristics with light weight and ease of processing. High numbers of large volume components with fine tolerances can be cost-effectively formed and used without assembly or modification. Applications for PEEK in the aerospace industry include critical engine parts as the polymer can withstand high temperatures and the tribological interaction of dry and lubricated material contacts. In aircraft exterior parts, PEEK provides excellent resistance to rain erosion, while for aircraft interior components, its inherent flame retardancy and low smoke and toxic gas emission reduce hazard in the event of a fire. In aircraft electrical systems, the polymer is used for manufacture of convoluted tubing to protect wires and fibre optic filaments. PEEK is also used to protect the wire harnesses used in commercial aircraft engines.
5.15.3 Market Trends 5.15.3.1 New Applications Victrex has developed a number of new applications for PEEK polymers in the automotive market in recent years as a replacement for metal and aluminium. These are described next. In the engine control system, the piston used to regulate airflow in the engine control system, comprises a metal bushing overmoulded with PEEK polymer. This was designed and manufactured by VDO Adolf Schindling AG, a business unit of the Mannesmann Automotive Division. ZF Friedrichshafen AG of Germany has replaced nitride metal with Victrex PEEK polymer for the starting disks in Ecomat local transportation bus gears. Robert Bosch GmbH of Germany has replaced metal with a carbon fibre filled grade of PEEK polymer for a number of functional components in its second generation ABS brake system. PEEK polymer oil screens are well established on Mercedes-Benz trucks. Developed by KarcomaArmaturen GmbH, Germany, the screens maintain their high mechanical strength after repeated exposure to hot oil at temperatures in excess of 180 °C. PEEK polymers are being used in the power transmission thrust washers from Borg-Warner Automotive. Used in Chrysler’s Viper high performance sports car, the washers withstand immersion in lubricating oil and operate over a wide temperature range. 5.16 Polyphthalamide (PPA)
5.16.1 Consumption Trends Market data is unavailable for PPA, given the limited number of suppliers.
82
Engineering and High Performance Plastics Market Report
5.16.2 Current Applications Solvay’s Amodel PPA resin features an excellent stiffness-to-cost ratio and a high strength-toweight ratio, both of which are superior relative to PBT, PPS, PEI, PET and PA 6,6. Its thermal performance is exceeded only by polyetheretherketone (PEEK) and some LCPs; its warpage and dimensional stability match PPS. Amodel resin has lower moisture absorption than PA 6,6, and its broad chemical resistance is exceeded only by a handful of more costly speciality polymers. PPA is used for many types of automotive components including sensors and solenoids, halogen lamp sockets and fog lamp assemblies, motor end caps and housings, fuel system components (flanges, fuel rails, fuel line connectors), anti-lock braking system components, cooling and heating system components (thermostat housings, oil filter housings, turbo charger air coolers). PPA is also used in a range of high temperature applications in the automotive electronics sector such as lamp sockets, electronics connectors, high-temperature switches, and sensors. PPA provides high strength, stiffness and impact resistance, plus a heat deflection temperature of 282 °C (540°F). PPA resin is also dimensionally stable and resists corrosion.
5.16.3 Market Trends 5.16.3.1 New Applications In 2002, Solvay Advanced Polymers announced a number of new automotive applications for Amodel PPA resins. PPA replaced aluminium in the fuel-air rail in a system developed by Synerjet for use in European motor scooters. Heat resistance was a major consideration in the selection of PPA, because of the proximity of the rail to the cylinder head where operating temperature can be as high as 160 °C. Delphi Automotive chose Amodel for the engine air control valve for an outboard engine application. Amodel was selected by Chrysler for the thermostat housing on the 2.4 litre, 4-cylinder vehicle that is standard on rear-wheel drive versions of the new Jeep Liberty sports utility vehicle. Amodel was selected for a key injection moulded component on the current and new GEN11 and Global series of brake vacuum boosters from Delphi Automotive Systems.

6 Electrical and Electronics Applications for Engineering and High Performance Plastics 6.1 Introduction This section examines the use of engineering and high performance plastics in electrical equipment and electronics industries, including telecommunications. Applications covered are electronics parts and components such as switches and connectors, business and electrical equipment housing, wire and cables, electrical lighting parts and lenses. The world electrical and electronics market has shown strong growth since the mid 1990s on the back of the Internet and telecommunications revolution. This has been extremely good news for plastics producers given the developing uses for plastic in E&E applications as a replacement for traditional materials such as metal and thermosets. In Western Europe, for example, the electrical and electronics industry grew at an average annual rate of 4.3% between 1995-2000. According to the APME, a total of 13.5 million tonnes of electrical and electronic appliances were produced, using 1.48 million tonnes of plastics in 2000. The amount of plastic material used in electrical and electronic products in terms of weight rose from 15% in 1980 to 20% in 2000. Cables and electrical components, with 595,000 tonnes, are the largest applications for plastics in 2000, followed by information technology and telecommunications. Large domestic appliances (refrigerators, dishwashers, microwave ovens etc.), is the third largest consumer. The domestic appliances sector was followed by consumer electronics (television sets, video recorders, radios, DVD players etc.) with 217,000 tonnes. Some 63% of the ABS used by the electrical and electronics industry annually goes into these applications. The segment of small domestic appliances (toasters, cookers, vacuum cleaners etc.) consumes a quite impressive amount of 151,000 tonnes of plastics. E&E sector growth has slowed considerably since 2000 due to the world economic slowdown and the major downturn in the IT and telecom sectors. Demand in the key high technology and electronics sectors was down by 30% in 2001. The mobile phone and IT sectors were down further in 2002, but are predicted to undergo a modest recovery from the second half of 2003. For 2005, APME predicts an increase of plastics consumption in the western European electrical and electronics industry to 1.9 million tonnes. At that time, the amount of plastics waste created in this segment is forecast to reach 1.1 million tonnes. 6.2 Trends and Market Drivers Important trends that are driving the E&E industry, which are influencing materials selection and performance include: 1. Thin-wall design, as a means of reducing system cost. 2. The ability to meet more stringent technical specifications. This includes the new European Union standard IEC-60335-1, which introduces tougher testing methods for materials used in unattended domestic appliances. 3. The quest for high quality and reliability, driven by expected application lifetimes of 5-20 years. 4. Growing market requirements for materials that are either halogen free, or have low halogen content. 85
Engineering and High Performance Plastics Market Report
5. Low warpage materials are being more generally adopted as a means of improving productivity and reducing shrinkage. 6. OEMs are increasingly looking to adopt a ‘smart design’ approach, focused on design for manufacturing and assembly (DFMA). Ease of installation for professional installers is also becoming increasingly important, and can in many cases be improved by using snap fit features and ductility of engineering thermoplastics. 7. Design flexibility offered by engineering thermoplastics is increasingly being used to differentiate products from the competition. In response to these trends, and as a means of achieving significant cost-cuts while continuing to improve quality and reliability. OEMs are increasingly using engineering thermoplastics, often replacing thermoset and metal. 8. Miniaturization, which increases the temperature and mechanical requirements of plastic materials. Further miniaturisation, pressure from competitors, and increasing demands on quality and durability will greatly promote the use of engineering plastics in electrical and electronic applications. 9. Consolidation and globalisation are well-advanced trends in the E&E industry. To support these trends, suppliers increasingly require a global sales and marketing network capable of supporting customers both locally, and on a global scale. Trends in the telecoms market that are affecting material selection are summarized below. 1. Technological convergence. Established technologies are merging with new ones, converging all communication tools into a single medium to which fixed or wireless connection is also becoming increasingly seamless. 2. Development of global standards for telecom equipment is beneficial to market growth. 3. Product differentiation and personalization is a key driver for individual product sales. 4. In the mobile phones, WAP phones and personal digital assistants markets, increased functional integration is placing ever-increasing demands on the materials from which these devices are made. 5. Growing demand for wireless communication, fuelled by the merging of cordless and cellular technologies; while the Internet and new developments such as IMT 2000 (the 3rd generation global communication standard) are redefining communication technologies. The collapse of the mobile telephone market in the second half of 2000 and subsequent downturn in other electronic markets, and especially computer production, has led to new structures emerging in the production market. The changes have prompted massive outsourcing of production steps by the big OEM electronics groups. During the boom, these companies built up huge capacities of their own, which are now recording high losses and acting as millstones around their necks. Only 13% of production has been outsourced so far but this figure could soon rise to 70%. Reports have also featured on the American-Asian production group Flextronics, with its successful strategy of all-in production for OEMs in central industrial parks located in low-wage countries. The company has grown rapidly and has more than 70,000 employees worldwide and sales of $12 billion in 2001. Many plastics converters working directly or indirectly in the electronic supply sector are now forced to cooperate with this group, whose main capacities are concentrated in China, Mexico and Hungary.

‘Enclosure systems’ is the magic word at the companies, which produce electronic components of all different types. These are systems that unite components in a wide range of materials and with different functions in an overall system that is generally encased in plastic. The overall market for these systems is put at some $4 billion for 2003. In line with this strategy of focusing on application customers, Dow Chemicals set up its new Dow Inclosia Solutions business unit for the electronics industry. Shortly after the company was founded, Finnish injection moulding company Eimo, announced a development partnership with the new Dow division. Further concentrations in the new, global marketplace through mergers, alliances and cooperation will be vital for the survival of small and medium-sized companies. 6.3 Future Prospects for the World E&E Industry The world electronics and telecom markets have experienced a substantial downturn since 2000. This has resulted in a major decline in demand for engineering and high performance plastics. There are signs that demand may be about to recover in several important end user markets, which should bolster future demand prospects for plastic materials. An examination of some leading indicators of future end user market demand shows that there is some cause for optimism. Tables 6.1, 6.2 and 6.3 present market forecasts by some leading IT and telecom industry consultants for key applications. Table 6.1 shows worldwide shipments of cellular phones. Table 6.2 shows personal computer sales and Table 6.3 shows monitor and display sales.

All three sectors are expected to show a substantial recovery in sales during the next two years. 87
Engineering and High Performance Plastics Market Report
Another major indicator of future demand for plastics in the E&E sector is the fortunes of the world semiconductor industry. According to the Semiconductor Industry Association (SIA), global semiconductor sales revenues for 2002 reached $140.7 billion, a 1.3% increase from 2001. The recovery that began in the final quarter of 2001 continued throughout 2002, which is a good performance, given the lackluster demand in the Information Technology market. For 2003, the SIA predicts 19.8% growth with revenues increasing to $169.3 billion. The worldwide wireless sector recorded the most vigorous growth. Unit sales of handsets grew by double-digits in the fourth quarter of 2002, producing growth of 13.2% in Flash and 6.8% in Digital Signal Processors. New subscribers continue to set records in Asia, particularly in China, which is adding some 5 million new users each month. PCs continue to be the single largest end market for semiconductors, accounting for 30% of total chip consumption. There is some evidence that the corporate buyer is returning to the market. During the December quarter due to increased PC demand, microprocessors and DRAMs were up 10.1% and 7.6% respectively. The consumer sector, including DVDs and digital cameras, continues to drive new growth, especially in application specific products. WiFi (802.11) has emerged as another brisk growth driver for semiconductors, as Wireless Local Access Networks (WLAN) are spreading rapidly around the world. The compound annual growth rate of WLAN is expected to exceed 35% over the 2000-2005 forecast period. Asia Pacific continues to be the world’s fastest growing market, recording a 29% increase in chip sales during 2002, pushing it past the Americas as the world’s largest market, with a 36% share. For the year 2002, chip sales declined 13% in the Americas, 8% in Japan and 8% in Europe from 2001 levels, as electronic equipment production continues an unprecedented migration to facilities in the Asia Pacific region. 6.4 Developments in Industry Regulations and Standards
6.4.1 The EU Directive on Electrical & Electronics Waste Under a new EU Directive on Waste Electrical and Electronic Equipment (WEEE), the electrical and electronics industries will be required to take back used computers, refrigerators and other scrap free of charge and recycle them according to environmentally friendly methods starting in 2005. This was agreed in October, 2002 by the EU Council of Ministers and the European Parliament conciliation committee. The directive foresees minimum quotas of 50% (household appliances) to 75% (large appliances) for mechanical recycling of electrical and electronic equipment starting in 2007. If the Council of Ministers and the European Parliament approve the compromise agreement, the new directive could take effect from 2003. Member states would then have until mid 2004 to transpose the legislation into national law. In any case, the process will consume considerable sums of money. The E&E industry in Germany, arguably the EU’s largest market for such products, has calculated annual costs of €350-500m for the handling of an estimated 1.1 million tonnes of scrap. The Industry Council for Electronic Equipment Recycling (ICER) is reviewing all the materials used in electrical products and will be recommending use of plastics that are compatible with recycling. They will then issue phase-out guidelines for other materials to suppliers. ICER claims that ideally the same polymer should be used throughout a product. If that is not possible, then compatible types should be used. This will help separation at end-of-life for recycling, as the resulting blend will be a usable alloy.

6.4.2 EU Directive (IEC-60335-1) on Unattended Domestic Appliances New flame retardant regulations relating to unattended domestic appliances have been introduced as part of the EU Directive IEC 60335-1, which aims to harmonise material testing methods. The new standards have particular relevance for polyamide and polyesters used in these applications, but are not a problem for polycarbonates, which pass the new tests, even without the addition of flame retardants. The new standard introduces the concept of the Glow-Wire Ignition Temperature (GWIT) test. The GWIT is a measure of ignitability of a material. To determine the temperature, three test specimens are brought into contact with a glowing wire, each for thirty seconds. The material passes if it does not ignite in any of the three specimen tests, and/or a flame is visible for no longer than five seconds. It receives its grade in the form of a so-called GWIT classification, which is 25 °C higher than the maximum temperature at the top of the glow wire that did not cause ignition of the material in the three tests. Plastics for parts carrying over a 0.2 A current in unattended domestic appliances such as refrigerators, washing machines and dishwashers must now undergo GWIT testing under the new regulations. A material can only be considered usable if a specimen proves that it has a GWIT of 850 °C at a thickness conforming to the wall thickness of the application. If it does it may be used without restriction for the domestic appliances listed in the standard. If it fails, further timeconsuming tests must be carried out on the material. 6.5 Polyamide
6.5.1 Consumption Trends The electrical & electronics sector is the second most important market for polyamide accounting for 24% of total world demand in 2002. The use of PA in electrical applications has grown significantly in recent decades due to its excellent flame retardancy, and good balance of mechanical and thermal properties. Polyamide also permits better functionality and design at a lower cost than competing materials such as thermosets and metal. Table 6.4 shows polyamide consumption in E&E applications by world region for the period 19992002. Table 6.4 Polyamide consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 171 184 173 180 North America 113 117 106 110 Japan 39 41 37 38 Rest of Asia Pacific 85 95 92 101 Rest of World 33 37 34 36 TOTAL 441 474 442 465
In 2002, total polyamide consumption in E&E applications amounted to 465,000 tonnes against 441,000 tonnes in 1999. Market tonnage declined in 2001 due to the major downturn in world E&E markets. Demand recovered slightly in 2002, particularly in China and Western Europe. Table 6.5 shows percentage share by world region of polyamide in E&E applications for the period 1999-2002.

Western Europe is the largest user of polyamide in E&E, accounting for 39% of total consumption in 2002. North America with 23% is the second largest market, followed by Asia with 30%. The share of China and other Pacific Rim countries is growing and is forecast to increase further in future because of the trend for E&E manufacturers to relocate production to lower cost economies.
6.5.2 Current Applications The main applications for polyamides in the E&E sector are low-voltage switchgears, connectors, bobbins and electromotor parts in a range of electrical equipment including household appliance and mobile phones. Low-voltage switchgears include miniature circuit breakers, residual current devices, fuses, switches, and relays and contactors. The connectors market consists of various sub-segments including automotive connectors, printed circuit board connectors, industrial connectors, wire-to-wire connectors, and various other types. Polyamide is used for the manufacture of tubes for protection of wire and cables. Due to its high temperature resistance, flexibility and chemical resistance, PA tubes are mainly used in automotive under-the-bonnet applications. Polyamide is also used to make the filaments in electric light bulbs.
6.5.3 Market Trends The key trends influencing further use of polyamide in E&E applications are discussed next.
6.5.3.1 Product Developments A new, easy-flow, special grade of Durethan polyamides was unveiled from Bayer AG in 2002. The company claims a 15% reduction in cycle time for the thin-wall technique. The low melt viscosity of these easy-flow variants also means that the filling pressure in the mould can be reduced by up to 30% for non-reinforced grades. These new grades are especially suitable for parts in the E&E sector. Bayer is also launching a number of new flame retardant Durethan grades that comply with the stricter testing methods relating to unattended domestic appliances (IEC60335-1). Possible applications include housing parts for pumps, electrical switches integrated into the control panel of washing machines or dishwashers and light-bulb sockets in refrigerators. In 2001, DSM Engineering Plastics introduced a new grade of Akulon PA6. The flow properties of ‘Akulon Ultraflow’ are up to 80% better than those of standard-grade PA6, and cycle times in injection moulding can be reduced by up to 25%. There are many possible new applications for the material, although it is especially suitable for thin-walled parts. DSM also introduced a flame retardant, reinforced grade of PA46 with its ‘Stanyl High Flow’. This has the same flow 90
Engineering and High Performance Plastics Market Report
characteristics as LCP and is 40% cheaper. As a rival to LCP, DSM is targeting electronics applications. In 2001, Mitsui Chemicals announced that it had developed a new grade of aromatic polyamide, which was designed to improve reflow solder resistance. In the electronics parts market, there is a shift from lead-eutectic solder to lead-free solder. Improvement of heat resistance is required for resins because lead-free solder has a higher melting point than conventional solder.
6.5.3.2 Inter-Polymer Substitution PBT and polyamide 66 are the most commonly used plastics for electrical connectors. The two polymers together have a market share of 10-15% in the $25 billion world market for connectors, of which North America accounts for $10 billion. For reinforced polyamide 66, an annual growth rate of 5-7% is forecast for the years 2000-2002. Higher performance plastics such as LCP and PPS are increasingly taking over in the electronics segment from the PA66 that has so far dominated the scene. Most electrical connectors (300 million per year) are used in computers and their peripherals, followed by telephone and data transmission applications. 6.6 Acrylonitrile-Butadiene-Styrene (ABS)
6.6.1 Consumption Trends The E&E sector is an important market for ABS accounting for 25% of total world demand in 2002. Table 6.6 shows ABS consumption in E&E applications by world region for the period 1999-2002. Table 6.6 ABS consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 130 144 120 122 North America 505 510 470 474 Japan 175 175 162 165 Rest of Asia Pacific 350 390 380 406 TOTAL 1160 1219 1132 1167
In 2002, total ABS consumption in E&E applications amounted to 1,167,000 tonnes against 1,160,000 tonnes in 1999. Market tonnage declined in 2001 due to the major downturn in world E&E markets.

91
Engineering and High Performance Plastics Market Report
and Western Europe with 10%. These consumption patterns largely reflect the location of major producers of IT and telecommunications equipment. The share of China and other Pacific Rim countries is growing and is forecast to increase further in future because of the trend for E&E manufacturers to relocate production to lower cost economies.
6.6.2 Current Applications ABS is the preferred material for IT and telecom equipment housings and covers because of its good toughness, strength, rigidity and chemical resistance, excellent surface finish and easy processing. The material also has excellent antistatic properties. ABS and PC/ABS blends are used in housings for many different products from personal computers, photocopiers and fax machines, to mobile phones and personal organisers.
6.6.3 Market Trends The key trend influencing further use of ABS in E&E applications is product improvement to comply with tougher international standards. World environmental safety standards such as TCO99, Blue Angel, White Swan or EU are getting tighter. At the same time resins must satisfy the fire safety criteria of UL. Producers are responding to these trends by introducing new eco-conforming, flame retardant (FR) technology. PC/ABS blends in particular, provide an exceptional combination of high flow and strength, which permits thinner walls, while reducing cycle time and improving aesthetics. 6.7 Polybutylene Terephthalate (PBT)
6.7.1 Consumption Trends E&E is the second most important market for PBT and represents 32% of total world demand in 2002. Table 6.8 shows PBT consumption in E&E applications by world region for the period 1999-2002. Table 6.8 PBT consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 33 36 34 36 North America 32 35 32 34 Japan 38 44 40 41 Rest of Asia Pacific 34 40 38 40 Rest of World 3 4 3 3 TOTAL 140 159 147 154
In 2002, total PBT consumption in E&E applications amounted to 154,000 tonnes compared with 140,000 tonnes in 1999. Demand was growing at a fast rate up to 2001 when market tonnage declined due to the downturn in world E&E markets. In 2002, demand was up slightly in Europe and North America, but showed much stronger growth in China and other Pacific Rim countries. Table 6.9 shows percentage share by world region of PBT in E&E applications for the period 19992002. Japan and ‘Rest of Asia Pacific’ are the leading users of PBT in E&E, accounting for 27% and 26% respectively of total world consumption in 2002. Europe is the next largest market, followed by North America. These consumption patterns largely reflect the location of major producers of IT 92
Engineering and High Performance Plastics Market Report
and telecommunications equipment. The share of China and other Pacific Rim countries is growing and is forecast to increase further in future because of the trend for E&E manufacturers to relocate production to lower cost economies.

6.7.2 Current Applications PBT is used in E&E applications for its electrical insulation properties, good heat resistance and chemical resistance. The main applications or PBT in the electrical and electronics industry include specialist light bulbs and lamp holders, housings for sockets and switches, printed circuit board connectors and sockets, junction boxes, capacitor housings, electronic connectors, fans and coil formers. Other applications include keytops for telephone keypads and LED displays. PBT is applied in a wide range of products in the lighting industry. Well known is the lamp base of the energy saving lamp, where PBT is selected for a combination of properties: heat resistance, dimensional stability, colour stability and laser markability.
6.7.3 Market Trends The key trends influencing further use of PBT in E&E applications are discussed next.
6.7.3.1 New Products A new, easy-flow, special grade of Pocan polyester compounds from Bayer promise a 15% reduction in cycle time for the thin-wall technique. The low melt viscosity of these easy-flow variants means that the filling pressure in the mould can be reduced by up to 30% for nonreinforced grades. According to Bayer, these new developments are especially suitable for parts in the E&E sector. Pocan DP 2004 is a non-reinforced, halogen-free PBT that is able to satisfy the criteria of IEC 60335-1, the European Union standard relating to materials used for unattended domestic appliances. Pocan DP 4035, is a halogen-free flame retardant polyester, with 30% glass fibrereinforcement for E&E applications. Both grades have improved electrical properties, such as smoke behaviour and tracking resistance, compared to traditional halogen based materials. These grades also offer advantages in material recycling, particularly with regard to imminent EU regulations on electrical waste. Compounders A Schulman and PolyOne have introduced a new PBT/PET blend aimed at electrical parts. The Schulman blend contains an additive mix that prevents the usual reaction between the two resins when blended. The new blend has higher mechanical and thermal properties than the comparable PBT only compounds. The blends contain 35% PET. A 30% glass-fibre reinforced grade has been used for housing an electric motor. PolyOne’s Bergadur PBT/PET blends deliver higher heat stability, better flow, lower shrinkage and better surface finish than pure PBT. Targeted applications are housings for electrical devices and automotive.

6.7.3.2 Development of PBT Polymer Blends PBT polymer blends combine the properties of partially crystalline PBT with those of amorphous thermoplastics such as ABS and polycarbonate. The amorphous partner improves the warpage behaviour (low thermal expansion, higher impact strength, and an improved surface quality), while PBT ensures the temperature and chemical resistance of the blend. These properties in general and the low warpage in particular, makes PBT blends a perfect choice for use on housings for electronic systems which require maximum imperviousness to all weathering conditions.
6.7.3.3 Lead-Free Soldering Methods The introduction of the lead-free soldering method has led to an increase in the temperature requirements of between 20-30 °C and thus created a demand for products with improved properties. The higher heat requirements for the materials used in the process may lead to increased use of high temperature thermoplastics at the expense of PBT. 6.8 Polycarbonate (PC)
6.8.1 Consumption Trends E&E is the second most important market for polycarbonate and represents 25% of total world demand in 2002. Table 6.10 shows polycarbonate consumption in E&E applications by world region for the period 1999-2002.

The ‘Rest of Asia Pacific’ is the leading consumer of polycarbonate in E&E, accounting for 48% of total world consumption in 2002. The share of China and other Pacific Rim countries is growing and is forecast to increase further in future because of the trend for E&E manufacturers to relocate production to lower cost economies. Europe is the next largest market with 25% of total consumption, followed by North America and Japan, each with a 12% market share.
6.8.2 Current Applications In the field of electrical lighting, polycarbonate is used to manufacture traffic light signal panels, globe lamps and other types of electric light covers. Its high transparency and light transmission means that lamp covers made from PC offer optimum luminous efficiency. The materials’ particularly high level of impact strength also provides extensive protection against accidental damage. In electrical installations/cables, PC is used in various applications including clamping and multipoint connector strips, power distribution box cover and housing, and switch panels. Its accurate reproduction of detail and high dimensional stability, together with its virtually isotropic shrinkage behaviour, ensure that complex parts will fulfil all their functions. PC is also used for high-grade, visible surfaces, such as various kinds of front panel, because of the wide range of surface finishes available. Polycarbonate is also applied to business and telecommunications equipment, usually in the form of a blend with PBT. It is used for data input keyboards, housing covers for computers, desktop calculators and magnetic discs. PC and PC/PBT blends are also used for mobile telephone housings. PC is valued in these items for its high impact strength, flame retardance, high heat resistance and good surface finish.
6.8.3 Market Trends The key trends influencing further use of polycarbonate in E&E applications are new products. In 2002, Dow commercialised a new polycarbonate grade for the information technical equipment market that uses a proprietary silicone-based flame retardant technology. Dow claims that it provides better thermal and light stability than those using bromine-based flame retardants, and has improved impact strength and heat resistance, than PC containing phosphates. Growth will be driven mainly by the use of flame-retardant PC grades for use in liquid crystal display monitors. GE Plastics introduced two new Cycloloy PC/ABS grades aimed at electronics applications that require flame retardance. The two new products are aimed at high heat and thin wall applications. The high heat series has a heat deflection temperature of 120 °C and thin wall UL94 performance with a VO at 1.6 mm. This makes it ideal for phone chargers, adaptors, battery packs, printers and copiers. The thin wall grade uses unfilled technology and has a VO at 1.2 mm. It is aimed at applications such as laptop PCs. 6.9 Polyoxymethylene (POM)

6.12.3 Market Trends The key trend influencing PPS growth in E&E applications is inter-polymer substitution. Higher performance plastics such as LCP and PPS are increasingly taking over in the electronics segment from PA66, which has so far dominated the market. Most electrical connectors (300 million per year) are used in computers and their peripherals, followed by telephone and data transmission applications. PBT and polyamide 66 are the most commonly used plastics for electrical connectors. The two polymers together have a market share of 10-15% in the $25 billion world market for connectors, of which North America accounts for $10 billion. 6.13 Polyetherimide (PEI)
6.13.1 Consumption Trends E&E is the second most important market for PEI accounting for 30% of total world demand in 2002. Table 6.20 shows PEI consumption in E&E applications by world region for the period 1999-2002. Table 6.20 Polyetherimide consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 0.8 0.9 0.8 0.9 North America 2.4 2.7 2.5 2.6 Japan 0.4 0.5 0.4 0.4 Rest of Asia Pacific 0.4 0.5 0.4 0.5 TOTAL 4.0 4.5 4.1 4.3
In 2002, total PEI consumption in E&E applications amounted to 4,300 tonnes against 4,000 tonnes in 1999. Demand rose sharply in 2000 but subsequently declined during the following year because of the downturn in world E&E markets. In 2002, demand recovered very slowly in most major world markets. Table 6.21 shows percentage share by world region of PEI in E&E applications for the period 1999-2002.

The regional pattern of consumption has been fairly stable during the period 1999-2002.
6.13.2 Current Applications Polyetherimide resins are inherently flame resistant with low smoke emission which makes PEI suited to a variety of applications in the fields of electrical equipment and electronics. In the telecommunications market, there is an increasing need for high heat resistant materials, especially for high-end connectors in the fibre optics segment. PEI resin offers high heat resistance as well as great flow for thin wall design. Other applications include electrical switches and controls, electrical motor parts, printed circuit boards and connectors. PEI is also used in so-called moulded interconnect devices (MID), because of its unique plating capabilities. PEI allows the combination of electrical functions with the advantages of injection moulded three-dimensional mechanical components in electrical control units, computer components, telecom and mobile phones, internal antennae of duplexers or microfilters, and fibre optic connectors.
6.13.3 Market Trends The key trend influencing further use of polyetherimide in E&E applications is new product development. To meet the ongoing needs for miniaturization in the electronics sector, (increased packing densities and more lightweight carrier materials) ceramic-filled PEI grades have been developed. These grades have excellent electrical and processing properties, and can also be easily metallised. They are suitable for applications such as circuit boards operating in the microwave range, as well as internal aerials, electronic chips and capacitors. 6.14 Polysulfone (PSU), Polyethersulfone (PES)
6.14.1 Consumption Trends E&E is the most important market for PSU/PES accounting for 29% of total world demand in 2002.

There were no major changes to the regional pattern of consumption during the period 1999-2002.
6.14.2 Current Applications PES and PSU have outstanding thermal properties, low creep, even at high temperatures, good flame retardancy, excellent insulation properties and high dielectric strength. The high stiffness, strength and dimensional stability permits use, for example, in pump impellers. Other applications found in E&E include various electrical components such as coil formers; plug-and-socket connectors; injection-moulded printed circuit boards; parts for power circuit breakers; parts for power contactors and relays; transparent covers for signal lamps and switchboards; lamp holders and lampshades; heat shields; sensors; chip carriers; chip trays; battery seals; TV components, hairdryer parts; oven, fan heater and projector components.
6.14.3 Market Trends The key trends influencing further use of PSU/PES in E&E applications are discussed next.
6.14.3.1 Inter-Polymer Substitution In the field of E&E, PES/PSU are subject to growing competition from other less expensive amorphous high temperature plastics due to rising cost pressures. The E&E sector can therefore be expected to show lower growth for PES/PSU in future.
6.14.3.2 New Applications In 2002, Solvay Advanced Polymers announced that a grade of its Radel polyphenylsulfone had been selected by Purolator for the housing of a transaxle fluid filter. The transaxle is part of an electronic powertrain being developed and tested for use in future fuel cell vehicles. Radel was selected for its excellent resistance to the corrosive fluid environment and high temperature resistance. In 2002, Radel was also selected in Saft’s SRM F3 series battery cells that are typically used for electrical backup systems in rail transport systems.

6.15 Liquid Crystal Polymers (LCP)
6.15.1 Consumption Trends E&E is the by far the most important market for LCP accounting for 75% of total world demand in 2002. Table 6.24 shows LCP consumption in E&E applications by world region for the period 19992002. Table 6.24 LCP consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 1.5 1.9 1.8 1.9 North America 3.2 3.8 3.5 3.7 Asia 6.6 7.9 7.0 7.7 TOTAL 11.2 13.5 12.3 13.3
In 2002, total LCP consumption in E&E applications amounted to 13,300 tonnes against 11,200 tonnes in 1999. Demand was growing at a very healthy rate up to 2001, when sales volumes declined due to the downturn in world E&E markets. There was however a substantial recovery in demand during 2002, particularly from Asia. Table 6.25 shows percentage share by world region of LCP in E&E applications for the period 1999-2002. Table 6.25 Percentage share by world region of LCP in E&E applications, 1999-2002 1999 2000 2001 2002 Western Europe 13% 14% 15% 14% North America 28% 28% 28% 28% Asia 59% 58% 57% 58%
Asia is the leading user of LCP in E&E, accounting for 58% of total world consumption in 2002, North America is the second largest consumer with 28%, followed by Western Europe with 14%. The regional pattern of consumption remained largely unchanged during the period 1999-2002.
6.15.2 Current Applications Liquid crystal polymers are produced through an ion-free polycondensation process. This makes LCP particularly well suited for applications in the electronics sector, where often ion concentrations of less than 5 ppm are required. LCP is applied for the manufacture of electrical and electronic components, connecting parts in fibre-optics and telecommunication devices of chemical processing machines, Other examples of electrical applications for LCP include lens holders for optical pick-up parts in CD-ROM, DVD, transformers for miniature modems in laptop computers, miniature relays, coil bobbins and sockets for halogen light fittings. In cellular phones, LCP has established a strong position in the area of connectors, chip card scanners and many other components.

6.15.3 Market Trends The key trends influencing further use of LCP in E&E applications are discussed next.
6.15.3.1 Inter-Polymer Substitution Higher performance plastics such as LCP and PPS are increasingly taking over in the electronics segment from the PA 66 that has so far dominated the market. Most electrical connectors (300 million per year) are used in computers and their peripherals, followed by telephone and data transmission applications. PBT and polyamide 66 are currently the most widely used plastics for electrical connectors.
6.15.3.2 New Applications In 2001, Siemens Dematic AG adopted DuPont’s Zenite LCP polymer for its new Polymer Stud Grid Array (PSGA) integrated circuit housings. These packages, which are only about 20% bigger than the chip itself, are the first time a thermoplastic resin has been used as a chip carrier. Zenite was selected for its high-temperature resistance, dimensional stability, easy melt-flow and good dielectric properties. Other recent new applications for DuPont’s Zenite LCP resins include: •
Two miniature solenoids use thin-wall coil bobbins moulded from Zenite LCP. The unit at the right operates a security lock, which formerly used a coil form consisting of a brass tube with an insulating sleeve and phenolic flanges assembled with adhesive. The solenoid at the left actuates a valve for medical equipment.
•
Miniature power inductors designed for SMT assembly consist of a coil wound on a ferrite bobbin core that sits on a base injection moulded from Zenite LCP.
•
The thin-wall capabilities of Zenite LCP were crucial to development of five space-saving miniature transformers for modems used in laptop computers.
•
Lens holder for optical pick up parts in CD-ROM, CD-RW and DVD.
6.15.3.3 Lead-Free Soldering Methods The introduction of the lead-free soldering method has led to an increase in the temperature requirements of between 20-30 °C and thus created a demand for products with improved properties. At the same time, materials that are resistant to high temperatures such as ceramics, metals and thermosets, may be driven out of their existing application areas and replaced by the more cost-efficient injection moulding process with LCP. 6.16 Polyetheretherketone (PEEK)
6.16.1 Consumption Trends E&E is an important market for PEEK polymers accounting for 20% of total world demand in 2002. Table 6.26 shows PEEK consumption in E&E applications by world region for the period 19992002. In 2002, total PEEK consumption in E&E applications amounted to 260 tonnes against 240 tonnes in 1999. Demand for PEEK in E&E applications was growing at an annual average rate of between
104
Engineering and High Performance Plastics Market Report
15-20% up to 2002 when there was a substantial fall in consumption. This is mostly due to the downturn in world E&E markets. Producers are confident that demand will recover sharply from 2003 onwards. Table 6.26 PEEK consumption in E&E applications by world region, 1999-2002 (000 tonnes) 1999 2000 2001 2002 Western Europe 0.08 0.10 0.13 0.10 North America 0.12 0.15 0.17 0.12 Asia 0.04 0.05 0.06 0.04 TOTAL 0.24 0.30 0.35 0.26

North America is the leading user of PEEK in E&E, accounting for 46% of total world consumption in 2002, Western Europe is the second largest consumer with 38%, followed by Asia with the remaining 16% of world demand. The market share of Western Europe increased during the period 1999-2002, while North America’s share has declined.
6.16.2 Current Applications PEEK polymers have excellent electrical properties, which make it an ideal electrical insulator, providing parts with long-term operating reliability over widely fluctuating ranges of temperature, pressure and frequency. Its inherent purity, combined with excellent mechanical and chemical stability, minimise contamination and maximise safety during the handling of silicon wafers. Outstanding thermal properties enable PEEK polymer parts to withstand the elevated temperatures associated with soldering processes. Some interesting examples of current applications include coaxial connector jacks used in handsfree telephone kits, surface-mounted trimming potentiometers, which are electro-mechanical devices, known as SMDs, designed to correct voltage or resistance errors in printed circuit boards, and as insulators for connector pins on under-sea environment control equipment.
6.16.3 Market Trends The key trend influencing further use of PEEK in E&E applications is development of new applications. PEEK is finding new applications in the E&E sector. For example, it is being used for manufacture of critical materials designed to transport and protect microchips and electronics. These products are mainly wafer carriers, which are designed for the storage and transport of semiconductors during production. Each wafer carrier is made up of eight parts that are welded and bonded together.

6.17 Polyphthalamide (PPA)
6.17.1 Current Applications The principal applications for PPA in E&E markets include high brightness LEDs and other optoelectronic devices, SMT electronic components, capacitor and chip carriers, heat sinks and switches. The trend in electronics toward miniaturization of insert-moulded connectors has driven the need for more contacts spaced closer together. This requires tighter tolerances and the use of higher flow resins for thinner walls. PPA resin can be used for sub-miniature, stacking printed circuit board connectors where high density is required. PPA resin is also surface mount compatible and, with its high strength and ability to be injection moulded with fast cycle times, is an excellent fit for applications such as cellular phone connectors. Finally, fully automated wafer loading systems use cassettes moulded from PPA resin to transport silicon wafers into process equipment where heat and chemical resistance are required.
6.17.2 Market Trends The key trend influencing further use of PPA in E&E applications is the development of new products. In 2002, Solvay Advanced Polymers introduced new grades of flame retardant Amodel PPA for use in E&E applications such as connectors, chip capacitors, cell phone components, circuit breakers, contactors, relays and switches. A special feature of the new products is their high conductive tracking index and glow wire flammability temperature performance. They are also more colour stable due to their thermal stability when processed at high temperatures.

7 Industrial Applications for Engineering and High Performance Plastics 7.1 Introduction This section examines engineering and high performance polymers used in industrial applications. The applications covered are predominantly injection moulded parts for industrial equipment and machinery. The section also covers building and construction applications and mining. Industrial applications are very demanding for plastics and are often found in hostile operating conditions. In particular, industrial applications require materials that can withstand sliding friction, high temperatures and have good chemical resistance. Machine elements, for example, are subject to sliding friction (slide bearings, rollers, thrust washers, piston rings, seals) for mechanical engineering, textile industry and office equipment. Industrial machinery and equipment may have to operate at continuous high temperatures, and be required to have a high degree of resistance to chemicals. 7.2 Future Prospects for Industrial Markets High performance plastics are making inroads into industrial applications that were once the domain of metals and thermosets. Engineering and high performance plastics have a number of advantages over traditional materials due to their flexibility in parts design, ease of processing and lightness. They are also tough, abrasion resistant and can withstand high temperature. Continuous product improvement and innovation means that there will be further scope for growth in many areas of industrial applications in future. Following a period of prolonged growth in industrial markets, demand for engineering and high performance plastics declined in 2001 due to the worldwide downturn in economic activity. GDP growth is expected to show a modest recovery during the next two years, which will lead to higher demand for plastics. However, there is unlikely to be a return to the double-digit growth rates that were experienced during the late 1990s. 7.3 Polyamide

has grown from 22% of world consumption in 1999 and should increase further during the coming years due to higher levels of economic activity.
7.6.2 Current Applications In mechanical engineering, POM is used because it is extremely dimensionally stable, with good sliding friction performance. It is also non-corroding, and has very low friction and wear, making it particularly effective for conveyor belts. It has exceptional resilience and excellent recovery, making it ideal, for example, for use in clips and snap connections. In machine construction, POM is used to manufacture many different parts including valves, small motor parts, chain links (for chain conveyors), ventilator rotors, guide rollers, thread guidance systems in spinning machines, ball and roller bearings, gear wheels and fastening elements.

7.7.2 Current Applications Polycarbonate sheet is used primarily for glazing systems in the construction sector, which is subject to highly specific requirements. PC sheet is also used for manufacture of signs and displays, and security shields. PC sheeting has a number of important features. It has excellent resistance to breakage over a broad temperature range, high light transmission of over 80% depending on panel type and thickness and good weather resistance. It also has low inherent weight. PC sheet is used, among other things, for glazing on lightweight, transparent hall and stadium roofs. Its low inherent weight compared to glass means that PC sheet offers considerable advantages in the design and static-equilibrium layout of the support structure. 7.8 Polymethyl methacrylate (PMMA)

7.10.2 Current Applications PPS has been replacing metal alloys, thermosets, and many other thermoplastics in mechanical engineering applications in recent years. PPS finds uses in many heavy industrial applications, including some outside the arena of reinforced injection moulding compounds. The thermal stability and broad chemical resistance of PPS make it exceptionally well suited to service in very hostile chemical environments. Besides moulded parts, PPS polymers find applications in fibre extrusion as well as in non-stick and chemical resistant coatings. PPS is well suited for the manufacture of mechanically and thermally highly stressed moulded parts. In machine construction and precision engineering PPS is used for various components such as pumps, valves and piping. PPS is also applied in oil field equipment such as lift and centrifugal pump components, oil patch drop balls, rod guides and scrapers. In the heating, ventilation and air conditioning (HVAC) equipment sector, PPS is used for compressors, muffers/reservoirs, hot water circulation components, induced draft blower housing, motor relays and switches, power vent components and thermostat components. 7.11 Polyetherimide (PEI)

Asia is the largest user of LCP for industrial applications accounting for 58% of total consumption in 2002. North America with 27% is the second largest market, followed by Western Europe with 15%.
7.13.2 Current Applications Many moulded parts for precision machinery that have traditionally been made from metal, thermosets, and a number of other thermoplastics, can be manufactured efficiently and economically using liquid crystal polymers. For these applications, the LCP family has excellent dimensional stability and creep resistance, especially at very high temperatures. When in a molten state its molecules tend to align with the flow, providing even greater strength in the flow direction, which also contributes to its superior wide-temperature range. The physical advantages of low thermal expansion and low mould shrinkage properties are further enhanced in thin-wall sections due to even more pronounced molecular alignment. In addition these resins are highly resistant to many chemicals, including concentrated acids, bases and hydrocarbons. They also display outstanding fatigue resistance and high dielectric strength performance over a very wide temperature range. 7.14 Polyetheretherketone (PEEK)
7.14.1 Consumption Trends In 2002, industrial applications accounted for 26% of total PEEK consumption. Table 7.23 shows PEEK consumption in industrial applications by world region for the period 1999-2002.

North America is the largest user of PEEK for industrial applications accounting for 44% of total consumption in 2002. Western Europe with 42% is the second largest market, followed by Asia with 14%.
7.14.2 Current Applications PEEK is used for a wide range of industrial applications because of the excellent physical properties and processability, outstanding mechanical properties, chemical and high heat resistance. PEEK polymers outperform metals and other materials in many components used in the industrial, chemical and processing industries. PEEK polymers are now finding applications in food contact applications, following approval from the US Food and Drug Administration. The material is being used in components from complex, high volume injection moulded parts, to machined stock shapes for low volume production. The main benefits of PEEK polymers for these applications are their high continuous operating temperatures (260 °C), high purity, chemical resistance and hydrolytic stability. PEEK is replacing metal in a range of high-end food processing equipment including the boiler pin and steam faucet of a range of high-end catering equipment, such as industrial coffee machines, food pump seals and automatic espresso machines. PEEK is replacing stainless steel in impeller wheels for regenerative pumps. It provides a significant reduction in wear, reduced noise levels and more consistent running properties. PEEK also offers increased application potential in pipe and hose couplings in modern connector technology. They are able to withstand exposure to pressures as high as 25,000 psi and to temperatures as high as 260 °C. Other new applications for Victrex PEEK polymers include: •
An 8 pin-connector has been developed for PEEK for critical applications where high temperatures are generated in oilfield explorations and production.
•
PEEK is also being used as an insulator component of non-invasive sanitary flow-through conductivity sensors. It is also being used for chopper seal faces used in mixing and blending equipment.
Victrex, the main PEEK supplier, is also developing new products. In 2002, Victrex introduced ‘PEEK-HT’, a cost- and weight-saving alternative to metal for industrial, automotive and aerospace applications that demand superior higher temperature resistance. The semi-crystalline, unreinforced polymer is claimed to offer ‘all the key characteristics of natural PEEK polymer, including toughness, strength and chemical resistance.’

8 Consumer Product Markets for Engineering and High Performance Plastics 8.1 Introduction This section examines the growing use of engineering plastics in consumer products. The main areas of application are domestic appliances, power tools, sports equipment, houseware, cookware and optical data storage media. The domestic appliances market covers: • • •
Small appliances: electric irons, kettles, food processors, etc. Large appliances: cookers, washing machines and refrigerators Brown goods: TV sets, VCR, DVD players, audio equipment.
The consumer products market is changing. Nowadays, consumer products such as washing machines, cookers and fridges, are being selected more on the basis of design and consumer perception, rather than pure functionality. Plastic has played a major role in improving design of many different consumer products and enabled manufacturers to gain a competitive advantage. Some of the most important consumer products using plastics are reviewed next.
8.1.1 Washing Machines The US is the world’s largest market for automatic washing machines. Japan is the second largest market, followed by Germany and France. The main applications, requirements and materials used are as follows. •
Display windows: Require good transparency combined with good scratch resistance. Polycarbonate is ideally suited for display windows.
•
Control panels and top frames: Aesthetic parts like control panels and top frames require the good balance of gloss and impact properties. PC/ABS blends are most commonly used.
•
Stabiliser covers: These very heavy parts, which stabilize the washing machine during washing cycles, generate a tremendous amount of vibration and therefore need to be isolated from the other components. PPO/PPE foams can be considered for the covers for these parts.
•
Door frames: Aesthetic parts that require good platability, PC/ABS blends are often used.
•
Electrical components: Require good mechanical properties (to prevent breakage during assembly), electrical properties, heat performance, tracking resistance and flame retardancy. PA, PBT and PPO/PPE resins provide good electrical, chemical and mechanical properties.
8.1.2 Vacuum Cleaners Between them, North America and Western Europe account for the vast majority of global vacuum cleaner sales. The main applications and materials used are as follows. •
Housings: Key requirements for vacuum cleaner housings are impact resistance, low warpage and aesthetics. PA, ABS and PC/ABS are often selected.
121
Engineering and High Performance Plastics Market Report
•
Window displays: Transparency and impact resistance are key requirements. Polycarbonate resin is most often used.
•
Exhaust grills: Key requirements are thermal performance and dimensional stability, PC/ABS resin is most often used.
8.1.3 Cookers The main applications and materials used are as follows. •
Aesthetic parts (knobs and panels): Several materials can be used for knobs and panels, depending on the technical requirements of the part. If aesthetics and impact performance are the sole requirements, PC/ABS and ABS resins can be used.
•
Electrical components (switches and timers): Require good mechanical properties (to prevent breakage during assembly), electrical properties, heat performance, tracking resistance and flame retardancy. PA, PBT and PPO/PPE blends provide good electrical, chemical and mechanical properties.
•
Door handles: Require good dimensional stability and good colour stability at high temperatures. PBT resin is most often used.
8.1.4 Fridges The refrigeration sector is one of the most mature sectors in the global appliance market and market growth is relatively low. The main applications and materials used are as follows. •
Liners and panels: Aesthetic parts that require a good balance of gloss and impact properties provided by ABS and PC/ABS.
•
Handles: Fridge handles also require the good balance of gloss and impact properties provided by PC/ABS and ABS.
•
Electrical components: Require good mechanical properties (to prevent breakage during assembly), electrical properties, heat performance, tracking resistance and flame retardancy. PA, PBT and PPO/PPE blends are often used.
8.1.5 Microwave Ovens The US is currently the world’s largest market for microwave ovens in terms of volume sales. Western Europe is the second largest market; followed by Japan. The importance of microwave oven sales to the major national markets varies significantly, and these variations appear to be related to cooking habits rather than wealth or economic development. For example, microwaves account for a high of 92.9% of sales of large cooking appliances in South Korea, compared to a low of just 15.5% of sales in Italy. In markets like the US and Canada, the importance of microwaves comes from the popularity of convenience foods. The main applications and materials used are as follows. •
122
Display panels, doorframes and handles: These exterior components require materials with high gloss, good scratch and impact resistance, and good printability. ABS and PC/ABS resins are well suited to meeting these requirements.
Engineering and High Performance Plastics Market Report
•
Door inner frames: These internal components, especially for the grill versions of microwave ovens, need to withstand significantly higher temperatures. PBT resin meets these requirements.
•
Display windows: Designed to provide very good visibility for timers and electronic displays, require good transparency combined with good scratch resistance. PC resin can therefore be used.
•
Switch holders: Require good heat resistance and flame retardancy. Depending on mechanical and design requirements, various materials can have a fit for switch holders, including PPO/PPE blends.
•
Air guides and fan covers: Require high heat resistance (in excess of 160 °C) and flame retardancy. PBT resin is often used for these applications.
•
Antennae: Require a material that is inert to microwaves, and offers perfect dimensional stability at high temperature (in excess of 160 °C). Polyetherimide resin can be considered for antennae.
8.1.6 Food Containers For food containers requiring good aesthetics, high impact and medium heat performance (< 100 °C), PC resin is most often used. For very high heat resistance (such as ovenable airline catering or microwavable containers), polyetherimide resin can be used.
8.1.7 Lawnmowers •
Petrol wheeled lawnmowers: Key requirements, apart from impact and shrinkage, are chemical resistance and thermal performance. In these applications, PC/PBT resins can be used.
•
Electrical lawnmowers: Key application requirements are impact resistance and shrinkage. In this case, ABS resin is most often selected.
8.1.8 Electric Irons The market trend is towards fully featured, highly specified and designed steam irons that encourage consumers to purchase more frequently. The top end of the market is performing particularly well and is driving the total iron market. The main applications and materials used are as follows. •
Heat shields: As the heat shield is very close to the metal sole of the iron, the key requirements for engineering thermoplastics used in this application are: thermal performance, heat ageing, dimensional stability and colour stability. PBT resin is most often selected for heat shields.
•
Housings – back parts and grips: Where aesthetics and impact performance are the primary requirements, PC and PC/ABS resins can be considered. Where aesthetics and thermal performance are the primary requirements, PBT resin is preferred.
•
Water tanks: The transparency required for water tanks means that PC resin is often selected.
8.1.9 Shavers The main applications and materials used are as follows. •
Electrical shaver housings: Key requirements for shaver housings are impact resistance, hydrolytic stability, resistance to face lotions and dimensional stability, with material selection
123
Engineering and High Performance Plastics Market Report
depending on the relative importance of each property. If resistance to face lotions is less important, and aesthetics and translucency are key requirements, PC resin may be the best choice. •
Electrical components: The electrical components of a shaver require good mechanical properties (to prevent breakage during assembly), electrical properties, heat performance, tracking resistance and flame retardancy. PBT and PPO/PPE blends provide good electrical, chemical and mechanical properties. PC and PC/ABS provide good aesthetic and impact properties.
•
Manual shavers: Hydrolytic stability and impact resistance are the key requirements for components including the grip and holding structure. PPO/PPE resin is often used for these applications.
8.1.10 Fryers Global sales are concentrated into four major markets: the US, the UK, France and Germany. Very slow growth is being recorded, reflecting a tendency to move away from deep fat fried foods due to health concerns. The main applications and materials used are as follows. •
Housings, lids, vapour filters, rings and buttons: Major requirements for these types of parts are related to thermal performance, stress-cracking resistance against cooking oils, dimensional stability, food contact compliance and aesthetic properties. PBT resin offers the right balance of properties to meet these requirements.
•
Electrical components: Require good mechanical properties (to prevent breakage during assembly), electrical properties, heat performance, tracking resistance and flame retardancy. PA, PBT and PPO/PPE blends provide good electrical, chemical and mechanical properties. PC and PC/ABS provide good aesthetic and impact properties.

If UV resistance is the primary requirement, acrylonitrile-styrene-acrylate (ASA) or PC/ASA can be considered; while if impact resistance is the primary requirement, PC and PC/ABS resins can be considered.
8.1.12 Food Mixers Food mixers, processors and steamers are a mature subsector of the small domestic appliance market. The main applications and materials used are as follows. •
Housings: Impact and heat resistance, as well as food contact compliance and colourability, are the key requirements for food processor housings. PC and ABS resins are most often used.
•
Bowls: In most cases, food processor bowls require very good transparency and high impact resistance, as well as food contact compliance. PC resin is often used.
8.2 Future Prospects for the Consumer Products Market Table 8.1 shows growth in consumer expenditure for major countries for the period 2000-2004.

Engineering and High Performance Plastics Market Report
Table 8.1 Growth in consumer expenditure for major countries, 2000-2004 (% change) 2000 2001 2002 2003 2004 USA 4.3 2.5 3.1 2.3 3.4 UK 5.2 4.1 3.6 2.9 2.5 Germany 1.4 1.5 (0.5) 1.1 2.2 France 2.8 2.8 1.5 1.7 2.8 Italy 2.7 1.1 (0.3) 0.9 2.2 Canada 3.7 2.6 2.6 2.9 2.9 Japan 0.5 1.4 0.8 0.5 0.8 Source: OECD
Consumer spending has held up well in the USA and UK during the last three years, growing at a faster rate than the economy as a whole. In most other major economies such as Germany, France and Italy, consumer spending has been far less resilient, with very low growth in recent years. The year 2003 probably marks the lowest point in the current economic cycle and growth in consumer spending is expected to increase during the next two years for all major economies, with the exception of the UK. Growth rates in consumer spending are, however, unlikely to be as high as those experienced during the period 1999-2000 for at least another couple of years. The more mature application areas such as large appliances, and audio and video equipment, are expected to show the lowest rates of growth in future. Plastics have also achieved a high rate of penetration in these applications, which will limit growth potential. The most exciting application areas for plastic will be in consumer electronics equipment such as DVD machines and video cameras. The sports equipment market also offers some interesting growth prospects for various polymers. 8.3 Market Trends
8.3.1 Growing Use of Special Effects Resins Consumers are demanding products that reflect their individuality and new styles in terms of design and colour are emerging much more quickly. Two plastics producers, Dow and GE Plastics, have responded to these trends by introducing lines of special effect resins. Dow has introduced a line of eight finishes called Effections, which can be used to create coloured moulded parts at a lower cost. Effections special effects come in metallics, glitters, fluorescents, translucents, colour shifting looks, marble and pastel. Instead of tying the new effects to standard colours and resins, the base finishes are customized for each application. GE Plastics has developed as range of resin colour effects under the Visualfx trade name. Twentyone different effects can be incorporated into most of GE Plastics resins to provide stable and consistently reproducible effects using standard tooling. As the colour effects are inherent in the resin the need for compounding and secondary paint operations are eliminated. 8.4 Polyamide
8.4.1 Consumption Trends In 2002, consumer products accounted for 11% of total polyamide consumption. Table 8.2 shows polyamide consumption in the consumer products market by world region for the period 1999-2002.

Competition in the material segment is between polycarbonate and PMMA producers. The PMMA producers such as Rohm and Atoglas, have identified the potential of the DVD market and are trying to introduce special PMMA formulations. But so far, the acrylate specialists have only managed to present first practical applications. Polycarbonate will be hard to displace. Polycarbonate is applied to a wide range of domestic appliances and consumer products. It can be used separately or in blends with ABS and PBT to manufacture a range of different parts from transparent windows and doors in washing machines, to housings and small domestic appliances such as hair dryers and electric irons. Polycarbonate is used in domestic appliances because it fulfils many different requirements. It has good electrical insulation values to ensure reliable protection to the device. PC has high dimensional stability in heat. It retains its dimensional stability at a long-term service temperature of up to 125 °C. Depending on the load acting on the component, non-reinforced grades of PC will remain dimensionally stable at up to 135 °C. It also has outstanding impact strength, which is retained over a prolonged period of time even when in contact with hot water (< 60 °C). PC is also transparent and permits a good surface finish. To improve the resistance of household appliances to humid conditions, GE Plastics extended its range of polycarbonates that are approved for food contact applications to include ‘Lexan H’. Even when subjected to heat and moisture over longer periods of time, this material retains its optical and mechanical properties, making it particularly suitable for applications such as steamer inserts for vegetables and heat-resistant containers. PC is also used for applications in toys and sports such as ships’ lights, binoculars and compasses. These applications require high mechanical strength and toughness, as well as weather resistance and precision mouldings. In the sports equipment market, PC/PBT blends are used for manufacture of ski bindings, bicycle components and skates. PC/PBT provides ductility, high flow and weatherability. GE Plastics also provides the opportunity for decoration using its VISUALfx effects. 8.8 Polyoxymethylene (POM)

Asia is the largest user of LCP in consumer products accounting for 59% of total world consumption in 2002. This substantial share is due to the location of many of the world’s leading consumer product manufacturers in Asia. North America is the second largest market with 27%, followed by Western Europe with 14%.
8.14.2 Current Applications LCP is used for manufacture of precision parts for consumer electronics equipment such as audio and video systems. It is also finding new uses in DVD, CD-ROM and CD-RW drives. DuPont for example announced that its Zenite LCP resins were being used for manufacture of lens holders for optical pick up parts in CD-ROM, CD-RW and DVD drives. The high flexural modulus/specific gravity (FM/SG) value of the Zenite® 1000 series enables higher resonance vibration frequency, which is required by optical pickup for precise and fast speed reading, in particular for high value top end drives. LCP also provides high flow, dimensional stability for precision moulding and low mould temperature for mass production.

9 Other Markets for Engineering and High Performance Plastics 9.1 Introduction Engineering and high performance plastics are used in a wide variety of other market sectors. These include: • • • • • • •
Packaging film and sheet (PA, PC) Blow moulded bottles (PC) Stock shapes (PA, PBT) Optical media (PC, PMMA) Plumbing (POM) Heating and sanitation (PSU/PES) Medical devices (ABS, PC, PBT, POM, PEI, PSU, PES, LCP, PEEK))
The medical devices market is probably the most important in terms of development opportunities for suppliers of engineering and high performance polymers. There are several main trends encouraging greater use of engineering plastics in medical applications. In medical technology, there is an increasing trend for ‘smart’ products. These are made possible by modern processes such as laser marking, two-component injection moulding and MID technology. Current examples include functional drug delivery systems like pens for active ingredient injection and needleless syringes. A key reason for selecting high-performance plastics is the precision with which finely detailed parts can be injection moulded from them. In addition, their excellent slip properties in sliding contact with other materials, high impact strength and low wear ensure reliable functioning of the application long-term. The pace of development is being set by microsystem technology, minimally invasive surgery, diagnostics and new drug delivery and packaging concepts for the pharmaceutical industry. Engineering plastics make an important contribution to reducing costs through functional integration. In medical markets, there are stringent regulatory requirements that must be met before a material can be used for a particular application. It is important to ensure that products that come into close contact with people do not contain any harmful substances that may damage health. Also, more stringent sterilisation methods are generally required for medical devices. Products and materials used for medical applications must be fully characterised, validated and tested for a variety of specifications including USP Class VI, ISO 10993, European Pharmacopoeia and FDA criteria. The EU Medical Devices Directive (93/42/EC) is the most recent framework for specification of medical devices in the European Union. 9.2 Future Prospects for the Medical Devices Market Table 9.1 shows healthcare expenditure for major world regions in 2000. The future prospects for growth in the medical devices market remain good. Plastics will continue to replace traditional materials for medical devices because of their greater design flexibility and excellent cost/performance characteristics. Also, overall spending on medical devices is expected to show continued growth. Spending on healthcare in all major world regions grew well in excess of average GDP during the last decade. For the world as a whole, healthcare spending rose at an
139
Engineering and High Performance Plastics Market Report
annual average rate of 6%. The highest growth occurred in ‘rest of the world’, which covers most of the developing countries of southeast Asia and Latin America. Spending on healthcare in the USA rose at an average rate of 7%, while average spend in the EU rose by 5.5% per annum. Table 9.1 Healthcare expenditure for major world regions, 2000 Average Medical Health Market size World Growth rate Devices per Expenditure ($billion) Market (%) 1990-2000 capita ($) (% GDP) EU 41.0 25.6 5.7% 66 5.5% USA 60.0 41.5 13.9% 125 7.0% Japan 24.5 15.0 7.1% 116 4.0% Rest of world 34.5 18.0 n.a. n.a. 15.0% TOTAL 160.0 100.0 n.a. n.a. 6.0%
The USA is the largest market for medical devices with a total value of $60 billion in 2000. The EU market is second largest at $41 billion, followed by Japan at $24.5 billion. In 2000, the EU accounted for 25.6% of the world medical devices market compared to an estimated 31.0% share in 1993. The reduction in overall market share is due partly to rapid expansion in medical technology sales in other markets, partly to market consolidation resulting in better distribution channels, and also because of reducing prices of medical devices. However, the decrease in world market share is also due to a significantly lower expenditure on healthcare (5.7% of GDP in EU compared to 13.9% in the USA and 7.1% in Japan). 9.3 Polyamide

9.6.2 Current Applications Polycarbonate is used in a wide range of ‘other markets’. It is used extensively in the optical industry for visors, protective lenses, industrial lenses and corrective lenses. PC has high transparency, dimensional stability, high temperature resistance, good processability and outstanding impact strength. In the medical devices market, polycarbonate is used in a range of different applications including haemodialysers, surgical instruments, cardiotomy reservoirs, blood centrifuge bowls, IV connectors, safety syringes and ophthalmic media. In the packaging sector, PC is used for manufacture of large reusable water bottles, reusable milk bottles and babies’ bottles. Polycarbonate is non-toxic and tasteless for contact with food, transparent, has high impact strength, is fracture resistant and can be easily cleaned. Polycarbonate is also used in a wide variety of other applications including fountain pens and ballpoint pens, food and catering containers, binocular housings, safety items such as protective goggles and machine hoods, and traffic signs with interior illumination. Some recent market developments are discussed next. GE Plastics has introduced Lexan EXL, an extra tough polycarbonate with added impact resistance and low temperature ductility. These attributes, plus its light weight, make it a great material for a variety of applications including telecommunications, portable electronics and outdoor equipment. It can replace metal and other engineering plastics. Lexan EXL sheet is finding new opportunities in vacuum formed parts, sound barriers and architectural applications. With its new polycarbonate grade ‘Makrolon Hygard’, Makroform GmbH, a joint venture of Bayer and Rohm, is attempting to develop a new market in security applications. Developed with armoured cars, banks or convenience stores or even prisons in mind, the product made of multiple layers of PC or PC/acrylic with bonding inter-layers, comes in six levels of protection, ranging from containment-rated sheet up to bullet resistant strengths capable of withstanding multiple rounds of fire from super-power hand guns. The hard coated surface also has exceptional resistance to abrasion and UV degradation. Polycarbonate is the favoured engineering polymer for production of many parts for the needleless syringe, one of the fastest growing devices in the medical market. It is preferred because of its burst strength, sterilisability and dimensional stability. GE Plastics has recently completed ISO10993 biocompatibility testing on the first tested grade in the Xylex PC.PBT resin product. This will allow the company to push ahead with its plans to further develop uses for Xylex in the field of medical devices. The material has a combination of strength, clarity, and chemical resistance. Target applications for Xylex include disposable medical supplies such as syringes, IV systems and fluid containers. Xylex resin also provides material solutions for non-disposable medical devices such as instrument panels and housings.

Engineering and High Performance Plastics Market Report
9.8.2.2 Medical Devices In the medical devices market, PMMA can be used in applications such as blood pressure filters, blood cell traps, peritoneal dialysis cassettes and blood cuvettes. Acrylic resins offer exceptional optical clarity, excellent sterilisability, processability, dimensional stability, bondability and excellent UV transmittance. High impact and medium impact grades are available with exceptional resistance to gamma radiation sterilization and superior UV transmission, for in vitro diagnostic use.
9.8.2.3 Packaging In packaging markets, acrylics are used for applications such as stoppers, jars, cosmetics containers, mascara holders, lipstick tubes, games boxes, surgical and dental instrument cases, musical instrument cases and musical boxes. Fast-growing new applications for PMMA include CD-ROMs and DVDs. PMMA is becoming very competitive to polycarbonate in regard to birefringence and refractive index as well as impact strength, heat resistance, water absorption and other properties. Mobile phones, organisers and pocket personal computers are also present and future growth drivers for PMMA moulding compounds. PMMA is also becoming more competitive with polycarbonate in these applications. Impact-modified PMMA, for example, ensures the desired break resistance. The major acrylics suppliers are also developing new products. Nova Chemicals for example, has commercialised a new acrylic copolymer, Zylar 390, which offers, clarity, toughness and enhanced chemical resistance. Potential applications for the polymer include medical devices, appliance parts, personal care products and consumer electronics. It is already being used as a surgical blood filter canister as a replacement for impact acrylics.

Engineering and High Performance Plastics Market Report
Solvay Advanced Polymers offers the broadest range of high performance materials of any supplier. These include PPS, PSU/PES, LCP, polyketones, polyarylamide, polyamide-imide and polyphthalamide. The company, which is headquartered in the USA, was established in 2001 following Solvay’s acquisition of BP’s advanced polymers business. Several Asian companies are developing their engineering plastics businesses through investment and joint ventures. The most broadly based operations in terms of product range include LG Chem of South Korea, and the Japanese companies Mitsubishi, Asahi Kasei, Sumitomo, Teijin and Toray. A number of suppliers concentrate on just one particular type of engineering plastic. All of the world’s leading acrylics suppliers for example, specialise only in PMMA production. Some single polymer companies are also leaders in their particular field. Victrex, UK, for example, is market leader in PEEK polymers, while Rhodia Engineering Plastics is a leading polyamide supplier. There are also many regional based engineering plastic suppliers. Many Asian companies for example, sell almost exclusively to countries in that region. Some of the smaller scale European companies such as Repsol, Radici and Enichem, sell mainly to markets in southern Europe. Most engineering and high performance plastics markets are characterised by few suppliers and a high degree of concentration. The top three world suppliers of polycarbonate (GE Plastics, Bayer and Teijin) for example control around 70% of total supply. The top three polyamide suppliers control 55% of world supply and the largest three ABS producers account for 57% of world production. The most extreme cases are polyetherimide, PPA and PSU, where there are only one or two world suppliers of each type of plastic. The trends in market concentration vary by plastic type. The more mature plastics such as polyamide, ABS, PBT and acrylics, saw an increase in the degree of market concentration during the period 1999-2000, following a series of mergers and acquisitions. In contrast, the fastest growing plastic types such as PPS, PEEK and liquid crystal polymers, have witnessed an increase in the number of suppliers as new companies have entered the market. The process of market consolidation in all types of engineering plastics markets is expected to continue in future. However, there was a marked slow down in the number of mergers and acquisitions during the period 2001-2002 due to the economic downturn and uncertain demand trends. There are signs that such activity may be recovering with two notable deals taking place so far this year. BASF acquired Honeywell’s polyamide business in January and DuPont acquired Eastman Chemical’s high-performance LCP business in March. There is also a clear trend for production to shift from western economies to the Far East and developing countries as major customers such as automotive and electronics industries grow their production in lower cost centres. A growing proportion of new capacity building has taken place in the Far East in recent years. At the same time, several engineering polymer producers have closed plants in the USA and Europe due to over-capacity and negative returns. The share of engineering polymer production in the Asia region is expected to grow much further in the coming years. Similar trends taking place in key end user markets such as automotive, electrical & electronics and domestic appliances, are encouraging the process of market concentration and globalisation in engineering plastic supply. The trend toward globalisation in end user markets means that customers are becoming more powerful and demanding of their suppliers. Customers require material availability and consistency on a global scale, which can only be met by global suppliers. Customers are also demanding more customised grades to differentiate themselves in the marketplace. Engineering polymer producers are responding to this growing trend by working more closely with key customers and developing new grades, colours and special effect polymers with one customer in mind.
155
Engineering and High Performance Plastics Market Report
Another trend is for engineering polymer producers to move further downstream by offering customers greater access to their knowledge and technology to create higher value services. A number of producers are capitalising on their expertise in part design through flow-simulation software. Dow Automotive for example is injection-moulding parts for the Ford Motor Co. in Brazil, and DuPont has a similar strategy. Meanwhile, Dow’s US-based Inclosia Solutions business is marketing innovative solutions for portable electronics enclosure applications. The company designs, produces (through subcontractors) and sells housings. 10.2 Polyamide (PA)

Celanex is Ticona’s trade name for PBT resins. Celanex is available in a wide range of grades, including unreinforced, glass and mineral reinforced, polymer blends, impact modified and flame retarded grades. BASF range of PBT polymers and compounds are sold under the Ultradur trade name. Glass fibrereinforced grades made from PBT and ASA (Ultradur S) with low warpage are also available. Automobile exterior applications are a major focus of engineering plastics research at BASF. In 1997, a 50.0% glass fibre-reinforced PBT (‘Ultradur B 4040 G10’) allowed production of components requiring high surface quality as well as extreme stiffness and rigidity for severe mechanical loads. Another new product to emerge from Ludwigshafen R&D was ‘Ultradur S’, a blend of PBT and ASA copolymer. Compared with other PBT types without the ASA component, this amorphous material is said to have extremely low warpage. Both materials are designed for use in windscreen wiper systems, door mirrors and headlamp housings. In 1998, BASF was the first producer to develop a halogen-free, flame-retardant polybutylene terephthalate (PBT), which retains the key properties of PBT, namely dimensional stability, chemical resistance and good toughness. The material is supplied under the brand name ‘Ultradur B 4000’. Compared with PBT that contains halogen, it offers a low smoke density and a very high tracking resistance. Pocan is Bayer’s trade name for its partially crystalline thermoplastic polyesters based on polybutylene terephthalate. Product offerings include PBT filled injection moulding grades, PBT elastomer modified and PBT standard non-reinforced injection moulding grades. PC/PBT blends, elastomer modified and non-reinforced injection moulding grades, are also available. DSM’s range of PBT resins and compounds are sold under the Arnite trade name. PBT products include standard PBT unfilled, 10%, 15%, 30% glass reinforced, toughened PBT with 0%, 20%, 30% glass reinforced and low warpage, 20% and 30% glass reinforced. Degussa supplies Vestodur PBT polymers and copolyesters. The company focuses on highperformance products rather than standard grades. Speciality products include laser-markable grades and high impact grades. Toray PBT resin was developed by combining Toray’s technological expertise in polyester polymerisation and resin-reinforced composites. Toray PBT resin is widely used in connectors and other automobile parts, bobbins, coil cases and other electronic and electrical components, and precision parts for office equipment. 10.4 Acrylonitrile-Butadiene-Styrene (ABS)

Vertical integration is a key feature of the acrylics market. The world’s three major acrylics producers: Lucite, Atoglas and Rohm, are all backward integrated into production of the methyl methacrylate (MMA) monomer and forward integrated into production of sheet and moulding compounds. Lucite International is the world’s largest producer of MMA with around a third of total production. It has MMA plants in Europe and the USA. Rohm & Haas has the world’s largest MMA plant with capacity totalling 360,000 tpa at Deer Park, Texas, USA. Rohm & Haas and Atoglas have an agreement whereby the additional production needs of both companies will be met from the Deer Park facility. The companies raised MMA capacity by 115,000 tpa in 2002. The world acrylics market has gone through a period of consolidation in recent years. ICI sold its acrylics business to Ineos (Lucite) in 1999, and BASF sold its moulding compounds business to IRG Plastics in 1997. Rohm & Haas, USA, sold its 50% stake in AtoHaas to joint venture partner AtoFina in 1998 while Degussa and Huls acrylics businesses were put together, following the merger of the two parent companies. There are three major suppliers of PMMA resins and moulding compounds to the world market: Röhm GmbH, Atoglas Acrylics and Lucite International. An enlarged Röhm GmbH was formed in 1999 from a merger of acrylics producer Agomer GmbH, the former Degussa subsidiary, into the former Hüls acrylics offshoot, following the merger of the two parent companies. The new, larger Röhm is the world’s number one producer of PMMA and number three in MMA feedstock. It has 19 subsidiaries producing at 18 locations, in addition to a network of marketing and sales centres. Rohm has two production facilities, for MMA both in Germany. The Worms facility has production capacity of 190,000 tpa and the site at Wesseling has total PMMA capacity of 90,000 tpa. Atoglas Acrylics is the market leader in the European PMMA market. The company was formerly known as AtoHaas, a joint venture involving Elf Atochem of France and Röhm & Haas of the USA. Atoglas has PMMA manufacturing and MMA facilities at Rho, Italy, with polymerisation capacity of 90,000 tpa and at Carling, France, with production capacity also of 90,000 tpa., and also has sites in the USA. The company produces a full range of cast and extrusion sheet and granules. Rohm and Haas sold its 50% share in AtoHaas to joint venture partner Elf Atochem S.A. in 1998. Atochem’s takeover of AtoHaas, gives it a 24% percent share of the world acrylic polymers market.

Glass-reinforced grades provide higher stiffness, strength, and creep resistance at elevated temperatures for structural-type applications. Mineral-filled resins offer enhanced dimensional stability and flatness. Some of the mineralfilled grades can be plated and epoxy-coated. Impact-modified grades provide significantly improved toughness with much higher strength and stiffness across a broad humidity and temperature range relative to toughened polyamides. Finally, glass-and-impact-reinforced grades provide an excellent balance of stiffness and impact resistance relative to either glass-or impactmodified grades alone. In addition to these, special grades formulated for applications requiring flame-retardancy, glycol-resistance, typically for automotive applications, and reflectivity, typically for optoelectronic applications such as high brightness LEDs, are available. In 2002, Solvay Advanced Polymers introduced a new range of high temperature Amodel flame retardant grades. The new grades are designed for critical electronics and electrical applications such as connectors, chip capacitors, cell phone components, circuit breakers, contactors, relays and switches. A notable feature of these new grades is their high conductive tracking index (CTI) and glow wire ignition temperature (GWIT). They are also more colour stable due to their improved thermal stability when processed at very high temperatures.
