FKM – Fluoroelastomers FKM is a fluorocarbon rubber, commonly referred to as fluorine rubber, VITON and FPM. They provide additional heat and chemical resistance. FFKMs are perfluororelastomer compounds containing an even higher amount of fluorine than FKM fluoroelastomers. They have improved resistance to high temperatures and chemicals and even withstand environments where Oxygen-Plasma are pres...
