The first FKM fluoroelastomer found its way into the market in the 50s when there was a need for high-performance sealings in the aerospace industry. In that time FKM was developed by the company Dupont Performance Elastomers and was brought to market under the trademark Viton®. Nowadays, multiple company’s manufacture O-rings from FKM and FPM fluoroelastomers.
Viton®, also known as FKM and FPM whereby FPM is the international name according to DIN/ISO, whereas FKM the short form is for the fluoroelastomer category according to the American standard ASTM.
Viton® is the registered trademark of DuPont Performance Elastomers, as is Tecnoflon® for Solvay Specialty Polymers, Dyneon™ for 3M Dyneon and DAI-EL™ for polymers from Daikin. All these are brands for FPM/FKM polymers and all stand for one single base material, which is fluoroelastomer.
What is a O-ring Viton®?
This fluoroelastomer is used in multiple situations where O-rings need to be resistant to high temperatures and chemical attacks. The FPM/FKM Viton® sealing rings are often used in the aerospace, the automotive and other mechanical equipment requiring maximum resistance to high temperatures and all kinds of chemicals, fluids and other media.
