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.
