Tefzel(ETFE)

DuPont™ Tefzel® is a modified ETFE (ethylenetetrafluoroethylene) fluoro-polymer .Tefzel® combines superior mechanical toughness with an outstanding chemical inertness that approaches that of Teflon® fluoro-polymer resins. Tefzel fluoropolymers is melt-processible thermo plastics. This is part of the DuPont family offluorine-based products. Tefzel is weather resistant, inert to most solvents and chemicals, and is hydrolytically stable. It has substantially better resistance to radiation .Electrically, Tefzel is an excellent low-loss dielectric, with a uniformity of electrical properties not normally found with other thermoplastics. Tefzel can best be described as a rugged thermoplastic with an outstanding balance of properties. Mechanically, it is tough, has medium stiffness (1,170 MPa, 170,000 psi), impact, and abrasion resistance. Tefzel is typically considered to have a no load continuous use temperature of 150°C (302°F).
