RUBBER COMPOSITION FOR HOSE AND HOSE

摘要

A rubber composition for hoses which comprises (A) a nitrile rubber comprising 45 to 55 wt.% units derived from an alpha , beta -ethylenically unsaturated nitrile monomer and 55 to 45 wt.% units derived from a conjugated diene monomer, (B) an epihalohydrin rubber, and (CA) a crosslinking agent for the nitrile rubber and/or (CB) a crosslinking agent for the epihalohydrin rubber and in which the nitrile rubber (A) accounts for 25 to 80 wt.% of the sum of the nitrile rubber (A) and the epihalohydrin rubber (B); and a hose comprising a layer made of a material formed by crosslinking the rubber composition. This hose is highly impermeable to fuel oils and has excellent cold resistance. It is hence suitable for use as a hose for automotive fuel oils.
