Tefzel® (ETFE)

Tefzel ® ETFE is a fluorocarbon-based polymer. ETFE is an abbreviation for the chemical name Ethylene TetrafluoroEthylene. and the Tefzel ® brand of ETFE is manufactured only by DuPont. This material was introduced to provide a material with both corrosion resistance and mechanical strength over a wide temperature range. The fluoroplastic family offers plastics with high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation.


  • Tefzel ® ETFE offers high purity, excellent chemical resistance,
  • Good permeability resistance
  • Excellent abrasion resistance over a
  • Temperature range of -300°F to +300°F (-185°C to +150°C).


  • Cryogenic applications — super-cold refrigeration components
  • Valves — linings, seats, seals
  • Compressors & pumps – linings and components
  • Electrical components — insulators, cable clamps
  • Gaskets — pressure, diaphragm, liquid gauge seals, fluid handling
  • Bearings — sleeve & thrust
