摘要

A hose which comprises an inner layer (1) and an outer layer (2) surrounding the periphery of the inner layer, wherein the inner layer is made of a thermoplastic olefin elastomer comprising polypropylene (PP) and an acrylonitrile/butadiene rubber (NBR), and the outer layer is made of a thermoplastic olefin elastomer comprising polypropylene (PP) and an ethylene/propylene/diene rubber (EPDM). The elastomer constituting the inner layer preferably contains 1 to 5 wt.% stabilizer comprising an amine compound or a mixture of a thioether compound and a hindered phenol compound. These elastomers desirably have a JIS A hardness of 60 to 90 as measured according to JIS K6301.
