Perfluoroelastomers - FFKM

Perfluoroelastomers are ideal for demanding sealing applications when customers require high quality parts like O-rings. FFKM resists over 1,800 different chemicals while offering the high temperature stability of PTFE (327°C). The unique properties of this material help maintain its seal integrity which can reduce maintenance, operating costs and improve safety. Kirkhill has formulated this material for a broad range of applications from an Ultra-pure semiconductor compound to a High Durometer ED (explosive decompression) resistant material.
