Abstract: An extruded multilayer seal member having an expanded temperature range and an improved compression set resistance wherein the seal member comprises a first fluoroelastomer as the inner layer of the multilayer seal member and a second elastomer as the outer layer of the multilayer seal member; and a method for manufacturing the multilayer seal member which comprises extruding a multilayer tubular structure, crosslinking the extruded multilayer tubular structure on a mandrel, cutting the multilayer tubular structure to provide a plurality of uniform seal members and recovering the seal members, are described.

Abstract: A biofuel hose that resists degradation when exposed to biofuels such as ethanol, an ethanol-hydrocarbon blend, and biodiesel, etc. for prolonged periods of time. The hose has an inner tubular member formed from a vulcanizable, hydrogenated, ?, ?-unsaturated nitrile-C4-C6 conjugated diene copolymer rubber or a blend of a vulcanizable, hydrogenated, ?, ?-unsaturated nitrile-C4-C6 conjugated diene copolymer rubber with a compatible polymer; a backing member around the inner tubular member wherein the backing member is formed from a vulcanizable, a, 1-unsaturated nitrile-C4-C6 conjugated diene copolymer rubber or a blend of a vulcanizable, ?, ?-unsaturated nitrile-C4-C6 conjugated diene copolymer rubber with a compatible polymer; and an ozone-resistant protective cover forming an outer surface of the biofuel hose. Preferably, the multilayer, biofuel-compatible hose includes a reinforcement member disposed between the backing layer and the ozone-resistant protective cover.

Abstract: An automotive vehicle vacuum brake hose that resists degradation when exposed to elevated temperatures up to about 175° C. for prolonged periods of time, the automotive vehicle vacuum brake hose comprising; an inner tubular member having an elastomeric matrix selected from the group consisting of acrylic elastomer and ethylene-vinyl acetate copolymer, and a protective cover around the inner tubular member. Preferably, the high temperature-resistant vacuum brake hose includes a reinforcement member around the inner tubular member and a protective cover around the reinforcement member.

Abstract: An extruded seal member having a corrugated axial surface exhibiting alternating peaks and valleys extending longitudinally along the axial surface of the seal member; a method for manufacturing the seal member which comprises extruding a tubular structure having a corrugated axial surface, crosslinking the extrude tubular structure, cutting the tubular structure to provide a plurality of uniform seal members and recovering the seal members; and a method of using such multilayer seal members, are described.

Abstract: An extruded multilayer seal member having an expanded temperature range and an improved compression set resistance wherein the seal member comprises a first fluoroelastomer as the inner layer of the multilayer seal member and a second elastomer as the outer layer of the multilayer seal member; and a method for manufacturing the multilayer seal member which comprises extruding a multilayer tubular structure, crosslinking the extruded multilayer tubular structure on a mandrel, cutting the multilayer tubular structure to provide a plurality of uniform seal members and recovering the seal members, are described.
