Which Chemical Resistant Seals Material To Use?

The below material diagrams provide a top-level overview of which material is suggested to use in certain conditions. Use it as a guide when discussing your fluid sealing requirements.

Perfluoroelastomer / FFKM

FFKM Chemical Resistance

Perfluoroelastomer / FFKM is a type of elastomer with a molecular structure that is very similar to PTFE. They both provide excellent thermal stability and almost universal chemical resistance.

M Barnwell Services range of Perfluoroelastomer / FFKM seals are the ultimate for sealing applications where chemical resistance and high-temperature performance are critical. In addition, we also have a specialist range of extremely low-temperature seals.
