Abstract

Method for manufacturing dimensionally stable and flexible hydraulic hoses, which comprises extruding a self-supporting elastomeric core tube, surrounding the core tube with reinforcing fibers and extruding an elastomeric sheath on the fibers, characterized in that it comprises tensilely winding a material of Offset, overlapping fibrous reinforcement on the core tube surface to provide a reinforcing layer, said fibers wrapping around the core tube to form an angle of approximately 50 to 65º with the longitudinal axis of the core tube thereby avoids substantial expansion of the core tube under pressure at elevated temperatures, and irradiating the hose with ionizing electrons until the core or sheath tube is no longer thermoplastic and has improved resistance to solvents, chemicals, and heat; Said core or sheath tube comprising, prior to irradiation, an extrudable thermoplastic composition of halogenated polyethylene, poly (butadiene-acrylonitrile) copolymer or poly (butadiene-acrylonitrile-acrylic acid) terpolymer which will crosslink when subjected to irradiation.
