What is ETFE, besides ethylene tetrafluoroethylene? ETFE is used to insulate wires and cables. It is used widely in the aerospace industry because of its material strength, resistance to radiation, chemicals, UV, and extreme temperatures.
This fluorine-based plastic is commonly referred to as its brand name, Tefzel™, trademarked by Teflon™. Like Teflon™ , this material is nonstick.
