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.
