Rubber hose comprising a liquid nitrile-butadiene copolymer incorporated into a partially hydrogenated unsaturated acrylonitrile- butadiene copolymer

摘要

An oil resistant rubber hose having an internal layer made of a vulcanized rubber composition of, or composed mainly of, partially hydrogenated unsaturated nitrile-conjugated diene copolymer rubber in which at least 50% of the conjugated diene units is hydrogenated. This rubber hose is superior in resistance to deteriorated gasoline and low temperature, and is suitable for the automobile fuel line.
