ETFE
ETFE is a fluorine based plastic, and could be described as a tough high strength version of PTFE. It has excellent chemical, electrical and high energy radiation resistance and a relatively high melting temperature.
Properties such as chemical inertness, outstanding weathering & heat resistance, excellent electrical insulation and low coefficient of friction enable ETFE to be exploited in a diverse range of applications such as football stadium roofing, wire insulation, insulated transformers, and surface coatings. ETFE is less flexible than PTFE but has far superior abrasion resistance.
