Automotive appHcations account for about 116,000 t of woddwide consumption aimuaHy, with appHcations for various components including headlamp assembHes, interior instmment panels, bumpers, etc. Many automotive appHcations use blends of polycarbonate with acrylonitrile—butadiene—styrene (ABS) or with poly(butylene terephthalate) (PBT) (see Acrylonitrile polymers). Both large and smaH appHances also account for large markets for polycarbonate. Consumption is about 54,000 t aimuaHy. Polycarbonate is attractive to use in light appHances, including houseware items and power tools, because of its heat resistance and good electrical properties, combined with superior impact resistance.

Antioxidants. Certain components of heat stabilizers (polyols, phosphites) also serve as antioxidants. The protection against oxidative attack is not as great in PVC as it is in certain ethylenically unsaturated materials. However, PVC compounds may require protection in the high-temperature service as in electrical wire insulation bisphenol A is often incorporated into the plasticizer for this purpose. Impact modifiers containing unsaturation such as acrylonitrile-butadiene-styrene polymers often require antioxidant protection. Hindered phenols such as butylated hydroxytoluene are often used for this purpose, especially when outdoor applications are involved. 

Brominated flame retardants (BFRs) are a structurally diverse group of compounds including aromatics, cyclic aliphatics, phenolic derivatives, ahphatics, and phthahc anhydride derivatives (Figure 31.3). The most common BFRs are tetrabromobisphenol A (TBBPA), polybrominated diphenyl ethers (PBDE), hexabromocyclododecane (HBCD), and polybrominated biphenyls (PBB). The primary use of TBBPA is as reactive additive in epoxy resin circuit boards, while decabromodiphenyloxide (DBDO) is primarily used in high impact polystyrene for electronic enclosures. PBDEs are typically used as the additive type of flame retardant in high impact polystyrene, acrylonitrile butadiene styrene, flexible polyurethane foam, textile coatings, wire and cable insulation and electrical connectors. 

The term acrylonitrile-butadiene-styrene copolymer (ABS) is used very broadly to define an important class of thermoplastic materials of which there are many different grades. These materials are used extensively in electrical a pliances, in the building and construction industries and in automotive componoits. Certain grades of ABS also find use as toughening agents in blends with other polymers, for example polycarbonates and polyamides (see Sections 19.8 and 19.9.3). 

As a measure of the level of sophistication of the industry the types of polymers consumed was as shown in figure 2. Others are mainly engineering thermoplastics (ETP), such as nylon, polyacrylates, polyacetals, polycarbonates, polyesters, and polpropylene oxide etc... These ETP s are growing at rates up to 20%. The main uses for plastic products are computer and business machine parts as well as design engineered products. The consumption of styrenic plastics (polystyrene acrylonitrile butadiene styrene - ABS) is high, relative to polyolefins, because of their demand in electric/electronic end-uses. 

Engineering plastic n. (1) A broad term covering those plastics, with or without fillers and reinforcements that have mechanical, chemical, electrical, and/or thermal properties suitable for industrial applications. R. B. Seymour, an outstanding authority, defined them as polymers thermoplastic or thermosetting, that maintain their dimensional stability and major mechanical properties in the temperature range 0-100° C. He listed the big five (among neat resins) as nylons, polycarbonate, acetals, polyphenylene ether, and thermoplastic polyesters. Among many others are acrylics, fluorocarbons, phenoxy, acrylonitrile-butadiene-styrene terpolymer, polyaryl... 

Acrylonitrile-butadiene-styrene (ABS) is one of the most important synthetic engineering resins because of its excellent properties of impact resistance, heat resistance, and chemical resistance along with being easy to fabricate, stable in finished size, and having good surface glossiness. ABS has wide application in machinery, vehicles, and electric products. 

Acrylonitrile-butadiene-styrene (ABS) is one of the most frequently used polymers in the production of electrical and electronic equipment, it also has widespread applications in automobiles, communication instruments and other commodities. Within the electrical and electronic sector, the quantity of recycled plastics could be increased via the recycling of ABS to reduce environmental, economic and energy issues. Table 2.5 illustrates some of the physical parameters of ABS. 

Acrylonitrile (H2C=CH-CN) is used as a co-polymer in approximately 25% of all synthetic fibers. It is further used for synthetic rubbers and for the production of acrylonitrile-butadiene-styrene plastics and styrene-acrylonitrile plastics. These ter- and co-polymers are used in the automobile industry and in the production of house wares, electrical appliances, suitcases, food packaging and disposable dishes. Acrylonitrile can also be a constituent in fabrics and paints (Bjorkner 1995). 

Polystyrene (PS) is a hard and transparent plastic. It is manufactured by polyaddition polymerization of styrene, CH2=CH-C6H5, using peroxide as an initiator. PS resin is one of the thermoplastics. As a foam, PS plastic is an important packaging and insulation material. Modified PS plastics with a co- or ter-polymer structure, e.g., styrene-butadiene (SB), styrene-acrylonitrile (SAN), acrylonitrile-butadiene-styrene (ABS), are used in household utensils, toys, electric appliances, handles, bags and pipes. PS products are also widely used in food packaging and disposable tableware. PS products can usually be identified by the metallic sound they produce when dropped on a hard surface. 

Chapter 6, Acrylonitrile-Butadiene-Styrene Resin, from LG Chem, describes subjects of particular cmrent importance, including flame retardant, transparent, heat resistant, and weatherable grades, especially ABS alloys such as ABS/PC, ABS/PVC, ABS/PA, and ABS/poly(methyl methacrylate). Flame-retardant compounds are used for components in electrical and electronic products, housings for computer monitors, printers, and copiers. The chapter provides special attention to environmental... 

PP has been blended with polyvinylchloride (PVC) for extrusion of pipes or electrical insulation [4]. The blends are compatibilized by addition of either methylmethacrylate-butadiene-st)TCne copolymer (MBS), a graft copolymer of acrylonitrile-butadiene-styrene-methylmethacrylate (ABSM), ethylene-vinylchloride copolymer (VCE), ethylene-vinyl-acetate-vinylchloride copol5oner (EVAc-VC), EVAc, etc. The blends also comprised other resin, viz. PE, PS or SBR, PMMA or PC, etc. 

A number of important products for which benzene is currently used may be manufactured using inherently safer green chemistry. An example of this is styrene. Styrene is widely used as a monomer for the production of polystyrene and ABS (Acrylonitrile-Butadiene-Styrene) resin. Polystyrene is commonly used in packaging and disposable service-ware materials, such as food/fast food packaging, furniture, appliances, electrical and electronic equipment, house-wares, and various related consumer products. The main uses of ABS... 

Some measurements of this property have been made in a range of electrically conducting polymers. These include epoxy resin/polyaniline-dodecylbenzene sulfonic acid blends [38], polystyrene-black polyphenylene oxide copolymers [38], semiconductor-based polypyrroles [33], titanocene polyesters [40], boron-containing polyvinyl alcohol [41], copper-filled epoxy resin [42], polyethylidene dioxy thiophene-polystyrene sulfonate, polyvinyl chloride, polyethylene oxide [43], polycarbonate/acrylonitrile-butadiene-styrene composites [44], polyethylene oxide complexes with sodium lanthanum tetra-fluoride [45], chlorine-substituted polyaniline [46], polyvinyl pyrolidine-polyvinyl alcohol coupled with potassium bromate tetrafluoromethane sulfonamide [47], doped polystyrene block polyethylene [38, 39], polypyrrole [48], polyaniline-polyamide composites [49], and polydimethyl siloxane-polypyrrole composites [50].
