Abstract: An abrasion-resistant multi-wall tubular article and a method of making same. The tubular article comprises an inner wall of polytetrafluoroethylene and an organic filler, an outer wall comprising polytetrafluoroethylene and an inorganic filler and a layer of polytetrafluoroethylene disposed therebetween. The article of the present invention has a high internal frictional efficiency over wide temperature and load conditions as well as an enhanced external crush and creep resistance and is particularly well adapted for use in motion transmitting cable assemblies and the like.

Abstract: This invention relates generally to cable assemblies, and more particularly to flexible cable assemblies of the type used in automobiles for transmitting rotary or linear motion along a predetermined path. In a particular aspect, the present invention relates to abrasion-resistant fluorocarbon polymer composites, such as polytetrafluoroethylene (“PTFE”) composites, having an unexpectedly high frictional efficiency under high load conditions and after long cycle times. The present invention relates to abrasion-resistant, anti-friction tubing formed from such composites, and to uses of such tubing as a liner for flexible, motion transmitting cable assemblies.

Abstract: An improved conduit for transporting fuel and/or fuel vapor or a motion transmitting member in an automobile comprising an inner tube comprised of fluorocarbon polymeric material and having an inner surface for contacting and containing fluids or a motion transmitting member, and a chemically etched outer surface having a substantial portion of the fluorine of the fluorocarbon polymer substituted by a polar moiety. The conduit further includes an outer tube comprising an inner surface comprised of polymeric material containing sufficient polar groups such that hydrogen bonding at the interface between the outer surface of the inner tube and the inner surface of the outer tube prevents substantial relative separation of or movement between the inner and outer tubes.
