Abstract
There is disclosed a hose comprising an inner layer as an inside layer and an outer layer disposed on an outer peripheral surface of the inner layer, in which an olefin thermoplastic elastomer comprising polypropylene (PP) and acrylonitrile-butadiene rubber (NBR) is used in the inner layer, and an olefin thermoplastic elastomer comprising polypropylele (PP) and ethylene-propylene-diene rubber (EPDM) is used in the outer layer to perform molding. A stabilizer comprising amines or a mixture of thioethers and hindered phenols is preferably added as a stabilizer to the olefin thermoplastic elastomer forming the inner layer. The amount of added stabilizer is set to 1 to 5 wt%. Moreover, the hardness of the olefin thermoplastic elastomer is preferably set to 60 to 90 in JIS A hardness.
