Heavy trucks and farm tractors are using RIM parts made with poly-dicyclopentadiene (P-DCPD). This material went from industrial applications to heavy-vehicle exterior components competing with fiber glass reinforced polyester (FRP) (Chapter 15) and aluminum. The big breakthrough in the heavy truck arena came in 1996 with the Kenworth T2000 18-wheeler, which had 14 exterior components of P-DCPD varying in size from an 80 lb roof fairing to smaller parts of 10 to 15 lb each. In the past couple of years P-DCPD RIM has made its mark in the hood of Class 8 heavy trucks. 

Such blends are attractive for a variety of end-use articles in the automotive market, especially for under hood and various exterior components. Some applications, for example connectors, have very thin wall sections and therefore require resins that have very low viscosities in order to completely fill the molding tools. The melt flow can be enhanced by mixing with a dendritic polyester resin. The inclusion of only 0.5% of a dendritic polyester resin can increase the melt flow rate by as much as 100%. °... 

In the automobile branch in particular, the design and finish of both interior and exterior components are subject to spiraling qualitative demands. The term premium class, coined by the automotive industry, is no longer the sole preserve of... 

The US National Highway Transportation Safety Administration plans to change its rear-impact test for cars from 30 to 50 mph. Tlie implications for fire safety are huge, as they would affect fuel systems, interior as well as certain exterior components. 

Nylon 6,6. Nylon 6,6 appears in automotive applications mostly in impact-modified, blended, and filled (mostly glass reinforced, with or with out impact modifiers) form. Impact modification of nylon 6,6 is of significant commercial importance, especially for automotive uses. Typical applications include fasteners for interior and exterior components, a host of connectors, holding fixtures, and radiator end caps, and a fairly common application is for air intake manifolds (Fig. 9.4). These applications rely on the ductility and toughness of impact-modified nylon 6,6 as a mechanism to connect assemblies or join components.

As with the interior, the exterior components must meet the needs of both function and fashion. A functional part like a door handle needs to have a good appearance (and retain it for the life of the car), and a largely decorative part such as a lateral strip clearly has a protective function, as well as a secondary styling function of masking an interface. It is accepted...

Maintenance of drums is limited to removal of such exterior components as large relief or control valves for off-site repair. Handling of these items can be achieved either by fixed davits or by mobile equipment. Davit arrangements for tall vertical drums should be in accordance with tower requirements. Davits are not usually furnished at horizontal drums if... 

Typical applications of nylon-based plastics also include fasteners for interior and exterior components, a host of coimectors, holding fixtures (Figure 17), and radiator end caps. These applications rely on the ductility and toughness of impact-modified nylon 6,6 as a mechanism to cormect assemblies or to attach components together. 

Boranes and carboranes are comprised of a-aromatic cage-like structures with boron and carbon vertices ranging from small tetrahedral to supra-icosahedral clusters. Despite more than four decades of work with this class of inorganic compound, there have been few reports of their photophysical properties, with a distinct paucity of information regarding luminescence. Carboranes have nevertheless been incorporated into photophysically active metal complexes, usually as ancillary components. But what of boranes, carboranes, and metallacarboranes (where a transition metal atom can either be an integral vertex in the polyhedral skeletal framewoik or an exterior component thereof) as chromophores themselves and their resultant optoelectronic behavior In this arena, there are very few contributors. 

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-boimet. PC/ABS blends are used for interior and exterior applications. 

PES/PSU are also used for aircraft interior and exterior components. 

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. 

Hydroxy functional acrylics are used in general industrial (GI) stoving rinishes in two distinct capacities. They are used to impart highly durable finishes for exterior components such as tractor sheet metal and cabs, fenders for earth moving equipment, or as one coat finishes in more wide ranging metal finishing such as office furniture, irons, microwave ovens, toasters, food mixers and blenders. 

PBT would typically be used for car interior or exterior components rather than underbonnet applications, including ash trays, windscreen wiper arms and door handles, or where a high-quality, weather-resistant surface is a key requirement.
