FKM Viton® rubber, also known as Fluorocarbon rubber, is known for its excellent oil and air resistance properties. FKM Viton rubber has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Extreme temperature and nearly legendary oil and fuel resistance makes FKM Viton rubber the choice for some of the toughest applications.
Depending on the grade, FKM Viton® rubber can operate continuously in excess of 200°C / 392 F° with intermittent spikes as high as 300°C / 570°F. Proper selection and compounding can provide low temperature resistance as well. It also possesses low gas permeability, low compression set and good mechanical properties.
FKM Viton® rubber is commonly used in aircraft engines, automotive fuel handling systems and high chemical exposure applications. FKM Viton® rubber is typically good with most chemicals and acids, but it’s good practice to check your Chemical Resistance Guide.
FKM Viton® rubber is attacked by amines, strong alkalis and many Freon’s. It also has limited resistance to steam, hot water, methanol, ketones, low molecular weight esters and nitro containing compounds like Skydrol, synthetic hydraulic fluids, certain esters and ethers.
