ABSTRACT:
High performance hoses are disclosed which are characterized by enhanced heat resistance, leading to prolonged service life, and hence are suitable for use in automobile power steering units. Inner tubes are formed of hydrogenated acrylonitrile/butadiene copolymer rubbers of a selected composition. The inner tubes may be of a double-layered construction composed of an inner layer of hydrogenated acrylonitrile/butadiene copolymer rubber and an outer layer of rubber composition which comprises specified amounts of a selected class of sulfurs, organic peroxide and triazine compounds combined with selected sulfur-curable base rubbers.
