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.
Temperature Range (dry heat)
low
high
-60 °F -50 °C
350 °F 175°C
Application Advantages
» excellent extreme temperature properties » excellent compression set resistance » very clean, low odor and taste
Primary Uses
Application Disadvantages
O-rings, rubber seals and custom molded rubber components for: » seals (static) for extreme temperature applications » food applications » medical devices » FDA applications
» typically not good for dynamic seals due to friction properties and poor abrasion resistance
