ETFE

ETFE or Ethylene tetrafluoroethylene is a thermoplastic polymer based on fluorine with a high durability. It is designed to have a high resistance to corrosion and to have a stable behaviour in a wide range of temperatures, making it a material used for demanding environments. It also stands out as a substitute for glass, as it weighs 100 times less and it is more insulating and transparent, favouring the passage of light.

ETFE Properties

Tensile strength with wide temperature range (-185 to 150)
Weather resistance (UV light resistant)
Resistance to high temperatures
Chemical resistance
Non-stick properties

ETFE Applications

Coating of electrical wiring
Fibre optic coating
Nuclear industry
Aerospace industry
Glass substitute, tensile structures in architecture

Some of the most used ETFE coatings are DuPont's Tefzel or Daikin's Neoflon ETFE.
