Introduced to the market in 1957, Viton™ Fluoroelastomers were designed to meet the demanding requirements for aerospace. Since its inception, Viton™ Fluoroelastomers offer new and innovative markets the same exceptional performance benefits that aerospace demands. Viton™ fluoroelastomers (FKM) provide excellent high temperature and chemical fluid resistance for sealing and fluid transport in aerospace, chemical manufacturing, renewable energy processors, electric vehicles (EV), internal combustion engines (ICE), oil and gas exploration, food manufacturing, and military.
Viton™ Physical Benefits
Viton™ Fluoroelastomers are designated by A, B, or F according to their resistance to corrosion from various chemicals or fluids.
Viton™ vulcanizates retain good mechanical properties compared to other elastomers when exposed to extreme hot and cold temperatures. Compounds remain elastic indefinitely when they are exposed to oven aging up to 204ºC. When exposed to freezing temperatures, Viton™ offers satisfactory performance in dynamic applications where temperatures can be between –18 to –23°C.
Excellent resistance to chemicals
Just like the temperature performance, its resistance to degradation from harsh chemicals such as solvents, oils, mineral acids, lubricants, and fuels is proven compared to any non-fluorinated elastomer rubber
For a broad range of substances and gases, such as oxygenated automotive fuels
Exceptional compression set and resistance to atmospheric oxidation, fungus, and mold
Allows for decent dielectric strength in various voltage applications
Low burning properties

Selecting Viton™ Fluoroelastomers
With the differences in physical property characteristics, it's essential to understand the desired benefit needed for your application. If resistance to compression set is vital in a seal material application, one of the A-types of Viton™ would be the better starting point for your formulation requirements. For example, if chemical resistance from hydraulic fluids is the end industrial application, starting with the F-types of Viton™ would be the family to sample.
