ETHYLENE TETRAFLUOROETHYLENE (ETFE)

Advantages

  • High impact resistance
  • Chemical resistance
  • Excellent stress-crack resistance

Limitations

  • Cost

Overview

Ethylene tetrafluoroethylene (ETFE) is essentially an alternating copolymer consisting of ethylene and tetrafluoroethylene segments. This a tough material with high impact resistance and useful mechanical properties up to near 350 degrees F (177 degrees C).

Its chemical resistance, electrical properties, and weathering resistance properties approach those of fully fluorinated polymers. Applications include components of pumps, valves, and other chemical process equipment; tie wraps; and electrical components.
