FLUOROSILICONE (FVMQ)
Fluorosilicone rubber which combines the good high and low temperature stability of Silicone with the fuel oil and solvent resistance of Fluorocarbons. It is most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to a dry heat limit of 400° F. Its features good compression set and resilience properties. It is suitable for exposure to air, ozone, chlorinated and aromatic hydrocarbons.
Fluorosilicone is designed for static sealing use. Because of its limited physical strength, poor abrasion resistance and high friction characteristics. Fluorosilicone is not recommended for dynamic sealing applications. It is also not recommended for exposure to brake fluides, hydrazine, or ketones.
Temperature Range (dry heat)
Standard Compound: -60°C to +175°C
Primary Uses
O-rings, rubber seals and custom molded rubber components for:
» Seals (static) for extreme temperature applications
» Aircraft fuel systems
Application Advantages
» Excellent extreme temperature properties
» Excellent compression set resistance and good resilience
» Good fuel oil resistance
» Very clean, low odor and taste
Application Disadvantages
» Typically not good for dynamic seals due to friction properties and poor abrasion resistance
» Not recommended for exposure to brake fluides, hydrazine, or ketones
