What makes FKM a premium rubber?
The scientific name of FKM is Fluoro-Elastomer. It is an extremely hard-wearing rubber compound highly resistant to salt water, aggressive chemicals, and extreme temperatures (as low as -45C and as high as +300C).
FKM shares notable similarities with HNBR. However, FKM has a higher density, resulting in a heavier feel compared to HNBR and additionally, FKM tends to be more flexible helping it mould to your wrist better.
