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: Disclosed is a flexible cable assembly for reliably transmitting motion along a predetermined path in high temperature environments. The assembly comprises a flexible tubular conduit, a crosslinked polyethylene tubular liner for the conduit and a core member movably contained within the conduit for transmitting force or torque along the predetermined path. The assembly preferably exhibits a fictional efficiency of at least about 80% over 500,000 cycles of the 200.degree. F. S-test.

Abstract: This invention relates to composites of fluorocarbon polymers, preferably polytetrafluoroethylene, which contain less than about 23% by weight polyamide-imide resin. More particularly, this invention relates to extrudable polytetrafluoroethylene composites which exhibit improved abrasion and friction resistance and other improved properties over a wide range of temperature and load conditions, and which are particularly adaptable for use as liners in wire insulation and in push-pull cable assemblies.
