FKM Viton Material

VitonFluorocarbon rubber has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. It has higher resistance to swell in high octane and oxygenated fuel blends.

Low temperature resistance is normally not favorable and for static applications is limited, although in certain situations it is suitable down to -40°F (-40°C). Gas permeability is very low and similar to that of butyl rubber. Special fluorocarbon compounds exhibit an improved resistance to acids, fuels, water and steam.

Names: Viton®, Fluorel®
