PCTFE (Kel F) - Polychlorotrifluoroethylene

PCTFE (polychlorotrifluoroethylene), commonly referred to as Kel-F® or Neoflon®, is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability.

PCTFE has excellent chemical resistance, radiation resistance, and flammability characteristics. The material has a useful temperature range of -400°F to 380°F. PCTFE is resistant to cold flow and it has the lowest coefficient of thermal expansion of any unfilled fluoropolymer. These characteristics make it an excellent choice when dimensional stability is critical.
