Automotive Applications for Epichlorohydrin Elastomers 660001

In this paper the properties of epichlorohydrin elastomers are discussed and automotive applications which could benefit from them are suggested.
The copolymer CHC (Hydrin 200) is an interesting new material for valve stem seals and O-rings because of its-65 to 275 F temperature service range and its excellent oil resistance. Suspension ball joint seals and spark plug boots may take advantage of its ozone resistance. It should also find acceptance in diaphragms because of its combination of fuel resistance, low temperature flexibility, and ozone resistance. In brake, radiator, and fuel line hose, the ozone and fluid resistance of CHC will be attractive, and the high impermeability to gases and refrigerants may make epichlorohydrin elastomers valuable in air conditioner systems.
