  • Duplex cured elastomer hoses and method of manufacture
    Patent number: 4806401
    Abstract: A method of manufacturing fiber reinforced silicone elastomer hoses and the hoses (25) resulting from the method are disclosed. The method comprises the step of extruding an unreinforced silicone elastomer inner tube (13) containing two vulcanizing agents having different activation temperatures. The extruded inner tube (13) is partially cured by heating the tube to the activation temperature of the lower temperature vulcanizing agent. The partially cured inner tube (13) is mounted on a mandrel (19) and wrapped with a fabric reinforced, calendered sheet (21) of uncured silicone elastomer containing a vulcanizing agent. External pressure is applied to the wrapped tube while the wrapped tube is heated to activate the second vulcanizing agent of the inner tube (13) and the vulcanizing agent of the wrapping sheet (21).
