Fluorosilicone Rubber Products

Trade Name(s):

ASTM D1418 Designation: FVMQ

ASTM D2000/SAE J200 Type, Class: FK

Standard Color: Blue

Description: Fluorosilicone rubber products combine the good high-and-low temperature stability of Silicones with the fuel, oil, and solvent-resistance of Fluorocarbons.

Key Use(s): Aerospace fuel systems. Auto fuel emission control systems. Primarily for static sealing applications.

Temperature Range: Standard Compound: -75⁰ to +400⁰F. (Dry Heat Only)

Hardness (Shore A): 50 to 80.

Features: Flurosilicone is most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to a dry heat limit of 400⁰F.

Although generally specified for aerospace use, due to its excellent fuel resistance and high-temperature stability, Fluorosilicone is becoming an increasingly popular material for a wider range of sealing applications.

Featuring good compression set and resilience properties, FS compounds are suitable for exposure to air, sunlight, ozone, chlorinated and aromatic hydrocarbons.

Limitations: Due to limited physical strength, poor abrasion resistance, and high friction characteristics, Fluorosilicone elastomers are not generally recommended for dynamic sealing. They are predominately designed for static sealing use.

They are also not recommended for exposure to brake fluids, hydrazine, or ketones.

Flurorsilicone products can be calendered (sheet) extruded, and molded into shapes.
