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