Fluoroelastomer Specialists
As elaborated by Industrial Rubber Goods in their article “Fluoroelastomers (FKM) / FKM Viton,” Fluoroelastomers (FKM) or FKM Viton represent a specialized class of synthetic rubber engineered to withstand extremely high temperatures. FKM offers unparalleled resistance to chemicals, heat, and oil, making it indispensable in applications requiring reliable performance above 200°C. Unlike conventional rubber, FKM is not a single entity but a family of fluoropolymer rubbers, classified based on their fluorine content—66%, 68%, and 70%.
FKM Viton: Viton®, a registered trademark of DuPont Performance Elastomers L.L.C., is a prominent fluoroelastomer introduced in 1957 to meet the rigorous demands of the aerospace industry. Renowned for its exceptional heat resistance and robust resistance to aggressive fuels and chemicals, Viton® quickly gained popularity across various sectors, including automotive, appliances, chemical, and fluid power industries. It holds worldwide ISO 9000 and ISO/TS 16949 registration, underscoring its high quality and reliability.
Properties of Fluoroelastomers (FKM): FKM exhibits outstanding resistance to oxidation, acids, fuels, and oils. While it has limited resistance to steam, methanol, and hot water, the latest FKM polymers boast a broader fluids resistance profile, extending their applicability to strong bases, ketones, aromatic hydrocarbons, and steam. Peroxide-cured fluoroelastomers offer superior water, steam, and acid resistance.
FKM Applications: FKM finds widespread use across various industries due to its premium reliability and durability, even in harsh environments. Applications include aerospace (O-ring seals, valve stem seals, fuel hoses), automotive (shaft seals, diaphragms, electrical connectors), and industrial (hydraulic o-ring seals, manifold gaskets, fuel tank bladders).
