FFKM (evolast®)

FFKM (evolast®) - Perfluorinated rubber


FFKM materials are elastomers ­offering the highest chemical and heat ­resistance. Some FFKM types can be ­exposed to temperatures over 300°C. The resistance to chemicals is ­nearly ­universal and ­comparable to that of PTFE. 


Standard compounds:

  • Evolast N894 (equivalent of Kalrez 6375)
  • Evolast N896 (equivalent of Kalrez 4079)


FFKM is well resistant to:

  • Almost all chemicals
  • Ozone, weather conditions, aging


FFKM is not resistant to:
  • Fluorine-containing compounds



Operating temperature range:

  • -15°C to +270°C 
  • with special qualities: -40°C resp. +340°C accessible
