PTFE materials have been used in medical applications for many years due to their excellent electrical, thermal, chemical and physical properties even under extreme conditions. Although PTFE can be processed in a paste extruder, this process has some distinct disadvantages in short lengths and mechanical properties like limited stress crack resistance and limited pressure resistance.
These disadvantages can be avoided by another manufacturing method, taping, which in turn introduces the reduction in abrasion due to the overlap of the tapes.
HEW-KABEL has developed a new process to manufacture expanded PTFE tapes. The uniqueness of the technology lies in the ability to produce taped cables with a very smooth surface, with no visible difference between extruded and taped products. Through careful selection of insulation and sheath material associated with expanded PTFE, the compressive stress of the cable is reduced so that the material fatigue of the cable is finally minimized and the service life increased. Because of its excellent sliding properties, these tapes can be implemented in strands and jackets.
