Definition - What does Ethylene Tetrafluoroethylene (ETFE) mean?

Ethylene tetrafluoroethylene (ETFE) is a type of plastic that is fluorine-based, tough and has a high strength profile. It is widely used for chemical and electrical applications because of its useful properties. However, wires made with ETFE insulation may be prone to corrosion.

Corrosionpedia explains Ethylene Tetrafluoroethylene (ETFE)

Ethylene tetrafluoroethylene (ETFE) possesses a number of useful properties:

  • Chemical inertness
  • Significant weathering resistance
  • High melting point
  • Heat resistance
  • Insulates against electricity
  • Low coefficient of friction

However, despite these properties ETFE insulated wires are prone to corrosion issues, especially when wires and connectors are bagged or located in confined areas where corrosive solutions, atmospheres or particulates become trapped.
