Glass-filled, toughened polyethylene terephthalate) (PET) resins can be readily moulded into highly impact-resistant structural parts for appliances and automotive components. The PET-based compounds are also suitable for construction (e.g. as structural members), equipment housings (e.g. printer and copier parts), agricultural applications (e.g. mower and tractor engine covers), materials handling (e.g. pallets and trays), furniture (e.g. office chair bases), as well as electrical and electronic applications. 

Electrical Properties. Polysulfones offer excellent electrical insulative capabilities and other electrical properties as can be seen from the data in Table 7. The resins exhibit low dielectric constants and dissipation factors even in the GHz (microwave) frequency range. This performance is retained over a wide temperature range and has permitted applications such as printed wiring board substrates, electronic connectors, lighting sockets, business machine components, and automotive fuse housings, to name a few. The desirable electrical properties along with the inherent flame retardancy of polysulfones make these polymers prime candidates in many high temperature electrical and electronic applications.

Then, the system based on the bubbler does not appear as the most convenient solution. A system based on electronic injection of water into the cathode inlet manifold, whose action depends on the uniformity of the individual cell voltages, could be the most effective technique for automotive applications. This solution would involve the use of an injection pump, which, however, would not affect significantly the FCS electric efficiency shown in Fig. 7.12. Another not predominant contribution to the energy losses due to the FCS auxiliary components can be identified in the electric consumption of the fan/radiator, which is useful to control the cooling water temperature on board of a vehicle [3]. 

Ethylene-propylene elastomers are one of the main choices of automotive chemists and material engineers for sealing applications, as well as isolation systems, weather stripping, electrical components, etc. Heat aging resistance up to 130°C can be expected with certain sulfur cures and up to 160°C with peroxide-cured compounds [3], They also respond well to high tiller and plasticizer loads. Typical properties are shown in Table 8.7 [4],... 

The first applications were those requiring autoclaving (medical equipment) or outstanding electrical properties at elevated temperatures. As compounding, stabilization, and processing skills improved, markets for Noryl expanded to Include office equipment, electronic components, automotive parts, water distribution systems, and general metal replacement. 

Alloys made by combining polyarylamide with PA and polypropylene (which could be hghtly glass reinforced) offer low water absorption, even at high PP levels, good impact resistance, and lower density, which reduces price per volume. Targeted applications include automotive body panels, and electrical components. 

The automotive industry has found several other applications where the additional cost of specialty may be beneficial. These areas are manifolds and tailpipes, catalytic converters, high-temperature fasteners, exhaust valves, airbag inflators, and other critical electrical components. The future use of these materials will depend on the benefits found in service and the changes in automotive technology that affect the corrosion conditions encountered by automobiles. 

Molded black or brown opaque handles for cookware have been familiar applications. Also used as a caramel colored impregnating plastics for wood or cloth laminates, and (with reinforcement) for brake linings and many under-the-hood automotive electrical components since the 1940s. Standard phenolics usually have wood flour filler. 

The market for commercial polymer blends has grown steadily over the past four decades. A recent estimate of the polymer alloy/blend market by volume for 2012 was about 2.2 billion pounds. The market was projected to grow to about 2.6 billion pounds by 2018 (BCC Research 2013). The principal markets for all blends include the automotive industry phone, computer, and other business machine housings electrical components such as connectors appliances consumer products recreational equipment and construction and industrial applications. 

While the polyketone terpolymer derived from carbon monoxide, ethylene, and propylene is economical with some attractive properties, such as heat, chemical, permeation, and abrasion resistance, it suffers from low-impact strength. One cost-effective approach to overcoming this shortcoming and upgrading its performance profile for automotive applications such as wheel covers, wheel caps, fuel filter necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gears, junction boxes, connectors, and seat backs, as well as electric/electronic components and durable household items involves blending with polyamides including a rubber modification (Lee et al. 2013). 

Such glass fiber-reinforced composites based on the unsaturated polyester thermosets are usually fabricated as sheet molding compounds (SMC) and bulk molding compounds (BMC). These are widely used in various metal replacement applications because of their cost-effectiveness, rigidity, light weight, and corrosion resistance properties particularly useful in transportation (cars and trucks), constmction, pipe, and tank applications. Automotive and tmck body panel and strucmral component applications of SMC include doors, hatchbacks, hoods, front grilles, etc. Some nonautomotive applications of SMC and BMC include sanitaryware (bathtubs, shower stalls, sinks), appliances, business machine, and electrical components. 

The good heat resistance and electrical properties of polysulfones allows them to be used in applications such as circuit boards and TV components. Chemical and heat resistance are important properties for automotive applications. Hair dryer components can also be made from polysulfones. Polysulfones find application in ignition components and structural foams. Another important market for polysulfones is microwave cookware. ...
