Fluorosilicones combine most of the attributes of silicone with resistance to petroleum oils and hydrocarbon fuels.
Low physical strength and abrasion resistance combined with high friction limit fluorosilicone to static seals.
Fluorosilicones are used primarily in aircraft fuel systems.



Primary Uses


O-rings, rubber seals and custom molded rubber components for:
» seals (static) for extreme temperature applications
» food applications

» medical devices
» FDA applications


Temperature Range (dry heat)




-75 °F
-59 °C

450 °F
232 °C


Application Advantages


» excellent extreme temperature properties
» excellent compression set resistance
» very clean, low odor and taste


Application Disadvantages


» typically not good for dynamic seals due to friction properties and poor abrasion resistance
