Abstract
The hose of the present invention comprises a soft hose wall (A) and a spiral reinforcement (B) for retaining the configuration of the hose. The hose wall (A) is formed with a composition comprised of: a resin component (A1) containing a diene-series or hydrogenated diene-series rubber component, and an olefinic resin; and a lubricant (A2). The rubber component may be a random or block copolymer of styrene and butadiene. The olefinic resin may be a polypropylene-series resin. The lubricant (A2) may be a higher fatty acid or its derivative (e.g., a higher fatty acid amide), a higher alcohol or its derivative, a hydrocarbon-series wax, an organopolysiloxane, or fluorine-containing resin. The present invention provides a hose which is lighter, free from PVC, and capable of maintaining excellent flexibility even used for a long period of time.
