Sinoflon fep-data sheet

Fep resin for wire, cable, tube, film and hose, etc.
Perfluorinated ethylene-propylene (fep) for wire and cable is the copolymer of tetrafluorothylene (tfe) and hexafluoropropylene (hfp) with excellent thermo-stability, outstanding chemical inertness, low friction coefficient, distinctive air aging resistance, vapor penetrating resistance, non-inflammability and superior electrical insulation. It is nearly stabilized in rather wide ranges of temperature and frequency. And it can be widely used as wire and cable in the field of aircraft, spacecraft, communication, computer, electricity instrument, high buildings and high temperature up to 200µ for a long time, etc, due to its excellent interruption & shielding resistance to communication signals. The thermoplastic process techniques can be used to fabricate useful products from fep.
