Fluorosilicone Rubber

Fluorosilicone rubber is an inorganic rubber compound consisting of low density, fluorinated silicone rubber. Fluorosilicone rubber combines the extreme temperature durability of silicone and the chemical resistance of fluorocarbon rubber. As a result of the silicone base, Fluorosilicone rubber has relatively low tear and tensile strength as well as a low abrasion resistance. Accordingly, Fluorosilicone rubber is not well suited for some applications.

At Pierce-Roberts, we use Fluorosilicone rubber for its resistance to chemical, fuel, oil, flame, weather, oxidation, ozone, silicate hydraulic fluids, alkalis, alcohol, and synthetic lubricants. Fluorosilicone rubber is principally used as a rubber gasket in fuel delivery systems and other specialty applications.
