PTFE film/foil

Skived films and foils are semi-finished products, available with a maximum thickness of 5mm. For thickness larger than 5mm, we direct you to section PTFE sheet. Width and length are according customer specification. The films and foils are skived from large PTFE blocks (round). For applications in which the PTFE film or foil must be bonded, we recommend a one side etched (or two side) etched PTFE film or foil. We can supply you the etching agent or the etched PTFE product itself.

Key properties of PTFE

  • Excellent chemical resistance
  • Working temperature -190°C to +260°C
  • Greatest resistance to fatigue (Wöhler curve)
  • FDA approved
  • Flame resistant - UL94V0
  • No stick
  • Low friction
  • UV-resistant (does not age)
  • Not hygroscopic (water absorption < 0,01%)
  • Very good dielectric dielectric insulation properties
  • Properties of PTFE can be improved by adding additives as carbon, graphite, glass etc.

Our films and foils are also available in PFA, FEP, ETFE, PCTFE, PVDF, THV and Tedlar.
