PURPOSE:To obtain the titled elastomer parts of high elastic modulus with outstanding oil and heat resistances, by forming with a composite material made by reinforcing a base layer made of chlorinated polyethylene with polyamide short fibers. CONSTITUTION:The objective elastomer parts for vehicles can be obtained by forming with a material made by incorporating and dispersing (A) a chlorinated polyethylene with a chlorine content 30-40% with (B) polyamide short fibers of a length 2-6mm and 0.5-10de. Said vehicle parts thus produced, due to especially high oil resistance for the component B with its adhesiveness to the component A extremely good, is outstanding in oil and heat resistances, furthermore, being greater in rigidity than that of conventional parts, thus capable of light-gage-light weight design, good in compression set characteristics, and also highly reliable in terms of sealability, etc.
