Information About

Fluoropolymer




Fluoropolymers were discovered serendipitously in 1938 by Dr. Roy J. Plunkett . He was working on Freon (for the DuPont corporation) and accidentally polymerized Tetrafluoroethylene . The result was PTFE (polytetrafluoroethylene), more commonly known as Teflon . It turned out to be a material with the lowest coefficient of Friction of any known solid material and inert to virtually all chemicals.

Examples of fluoropolymers:
  • PTFE (polytetrafluoroethylene, Teflon )

  • PFA (perfluoroalkoxy polymer resin, also known as Teflon)

  • FEP (fluorinated ethylene-propylene, also known as Teflon)

  • ETFE ( Tefzel ), ( Fluon )

  • ECTFE (Turcite, Halar)

  • PVDF (Kynar)

  • TFE (trifluoroethanol)

  • FPM

  • CTFE

  • FFKM (Kalrez, Tecnoflon FFKM)

  • FKM ( Viton , Tecnoflon)


Fluoropolymers may be either Thermoset s or Thermoplastic s.
