PTFE or Polytetrafluoroethylene is a fluorine-based polymer discovered in 1938. Thanks to the replacement of hydrogen atoms by fluorine atoms, it is an inert material that is highly resistant to chemicals. It is the fluoropolymer with the lowest coefficient of friction and the highest resistance to temperature, with a great impermeability and maintaining its qualities in humid environments, making it a very useful material in the most demanding industrial sectors.
- Works over a wide temperature range (-270°C to 270°C)
- Electrical insulation
- Thermal resistance
- Corrosion resistant
- Resistant to chemicals
PTFE Coating Applications
Teflon is the trademark under which PTFE was first marketed, initially registered by DuPont and now owned by The Chemours Company. Teflon has been evolving, having different versions from the original Teflon PTFE as Teflon PFA (perfluoroalkoxy) resin and Teflon FEP (fluorinated ethylene-propylene) copolymer, for further handling in the industry.
