The technologies of recycling Reaction Injection Molded (RIM) polyurethane polymers have been refined to the stage of commercial reality. Chrysler Corporation is in the process of qualifying the use of automotive fascia containing recycled RIM thermoset polymers. This will mark the first use, in North America, of a recycled RIM thermoset polymer into a class A surface exterior automotive part. This was made possible through a close working relationship with Polyrim Green Lane, a division of Decoma International, and Dow Plastics. The described process technology allows the recycle of painted and unpainted process scrap, and potentially post consumer scrap, into the same application without the loss of surface quality or polymer performance. This will divert these materials from the waste stream that is currently being landfilled.
Both conventional and newly developed materials used in unique applications have played an important role in making the Chrysler gas turbine engine a practical powerplant. The new low-cost materials developed by Chrysler Metallurgical Research include, (a) a series of iron-base super alloys having equivalent or superior life to aircraft type alloys, (b) heat resisting iron aluminum alloys for elevated temperature service under low stress application, and (c) long life rubbing seal materials that operate satisfactorily from ambient temperature up to 1200°F and above. These materials appear to meet all present or immediate high temperature alloy requirements for a competitive mass produced automotive turbine.
