Tefzel - Model ETFE - Ethylene Tetrafluoroethylene Modified Copolymer - Brochure

ETFE (ethylene-tetrafluoroethylene modified copolymer) is often referred to by DuPont’s trade name, Tefzel®. ETFE provides excellent resistance to chemicals, abrasion, corrosion and weather as well as excellent mechanical strength and stiffness. It also has a low dielectric constant, uniform electrical properties, a continuous service temperature of 300° F and retains its abrasion resistance at temperatures ranging from -300° F to 300° F. Low friction and good electrical and thermal insulation also can be found in ETFE. Typical applications include cryogenics, compressor and pump linings and components, bearings, gaskets, wire insulation, electrical components, process vessels, wires and cables, and food and pharmaceutical packaging films.
