Abstract

See full text

A method of forming a polytetraflouroethylene (PTFE) insulation layer over a metallic conductor of a processed product includes the steps of extruding PTFE over a metallic conductor, and heating the PTFE to a temperature substantially below that of the sintering temperature of PTFE to form a sintered PTFE skin over an unsintered PTFE core.
