Fluorosilicone FVMQ O rings

Fluorosilicone (FVMQ)

General Description:

Fluorosilicone is a widely used elastomer that can be compounded to meet a wide range of applications.  The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuels and mineral oil resistance but poor hot air resistance when compared with silicone. This material is widely used in semiconductor Ashing equipment for its resistance to oxygen plasma.

Chemical properties

Excellent resistance to hydrocarbons oils, petroleum fuels, mineral and synthetic oils and greases. It is suitable for use with mineral-based hydraulic fluids.

Typical operating temperatures

-60°C to +180°C continuous, or +200°C intermittent.

Fluid sealing duties

Widely used for static seals in aerospace fuel systems. Its more general use is limited by high gas permeability, low tensile strength and poor resistance to tear and abrasion.

Features:

Excellent flexibility and resistance to compression set

Excellent resistance to aging and weather-sunlight

Resistance to oxidizing chemicals, animal and vegetable oils, fuels, aromatic and chlorinated solvents

Resistant to diluted alkalies, diester oils, aliphatic and aromatic fluorocarbons, silicone oil, toluene, benzene, ozone and oxidative environments.
