FFKM (Perfluoro rubber)

FFKM (Perfluoro-rubber)


  • Air temperature operating range: -5 °C / +320 °C
  • Shore A hardness ranges from 75 to 85
  • High stability against aggressive media and in polar/non-polar media
  • Reliable in both static and dynamic applications


Ideal for demanding seal applications, whenever the customer needs high-quality parts such as O-rings. The unique properties of this material help to maintain seals, which can result in less maintenance, reduced operating costs and improved safety. Only seal elements made of perfluor-elastomer achieve the virtually universal chemical resistance of PTFE, without having to miss the typical sealing, resilience (compression set) and creep resistance of rubber.
