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.

Multilayer extruded seal and method for manufacturing such seal

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.
