Tefzel™ ETFE (ethylene-tetrafluoroethylene) resins are melt-processable copolymers with a reputation for excellent physical toughness and resistance to radiation, chemicals, UV, and extreme temperatures. They also can be customized for desired color, reinforcement, and conductivity levels, allowing them to be used in a variety of high-performance products and components. Advantages of Tefzel™ ETFE:
  • Low wear factor (1/10 of reinforced nylon)
  • High-impact strength and dimensional stability
  • Heat resistance with a rating for temperatures up to 150 °C (302 °F) based on the 20,000-hour criterion and good creep resistance
  • Low flammability
  • Specific gravity of 1.7
  • Strong weathering capabilities (up to at least 20 years)
  • Low-moisture absorption
  • UV resistance
  • Resistance to solvents, acids, and bases
Tefzel™ ETFE resins have multiple applications, which include:
  • Electrical insulation and heat-shrinkable tubing
  • Wire and cable, including wrapped computer terminations, heavy power circuits, steel mill cables, airframe wire, downhole well logging cable, and rapid transit car and locomotive control wire
  • Load-bearing applications in abusive environments
  • Cable and hydraulic line clamps, cable straps, and other fasteners
  • Valve linings
  • Pressure-sensitive tapes, flexible printed circuits, liquid pouches, and other constructions needing a film form
