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.

Abstract: A hose comprises a hose wall comprising a soft synthetic resin and a hard spiral reinforcement fused with or bonded to the hose wall for retaining the hose configuration. The hose wall comprises at least one layer of a chlorine-free thermoplastic elastomer such as a polystyrenic thermoplastic elastomer, a polyolefinic thermoplastic elastomer and a polyurethane-series thermoplastic elastomer. The reinforcement comprises a hard wire and a covering resin layer formed on the hard wire. The hose wall and the covering resin layer are formed with the same series elastomer. This hose is lighter and free from PVC resins, and has the same flexibility as that of the conventional PVC hoses.
