Sep 28, 2020

Chemical resistance 

FFKM Rubber withstands attack by more than 1800 chemical substances


Broad temperature capability

FFKM retains high levels of resilience up to temperatures as high as 250 °C (482 °F) and down to –21 °C (–5.8 °F). Under pressurized sealing conditions,it has demonstrated low temperature performance down to –40 °C (–40 °F) in customer laboratory tests.

We also have AFLAS PM-3000 Chemical Resistant FFKM O RING

It with better price than Kalrez
AFLAS® FFKM Series is a new perfluoroelastomer product line classified as an FFKM. AFLAS PM-3000 is a semi-commercialized elastomer having the chemical structure derived from tetrafluoroethylene and perfluoroalkylvinylether. This chemical structure offers outstanding resistance to chemicals, oils, solvents, and more. PM-3000 is a peroxide-curable perfluoroelatomer.
