Fulorosilicone Rubber(FVMQ)

Fluorosilicone Rubber (FVMQ)

Fluorosilicone is like silicone rubber,bonding trifluoropropyl,methyl,and vinyl as side chains.The mechanical and physical properties are similar to VMQ.However,FVMQ offers improved fuel and mineral oil resistance,but poorer hot air resistance then standard VMQ

Cure system-Sulfur-Cured

Standard FVMQ compounds are peroxide-cured

Other Common Variations

●FVMQ offers excellent low-temperature flexiility and good resistance to fuel and aromatic mineral oil.It is usually applied in contact with jet and automotive fuels,most solvents,and engine oil especially in aerospace industry

●FVMQ compounds meet MIL-R-25988 specification

Performs Well In…

●Fuels

●Aromatic mineral oils

●Benzene,Toluene

●Ozone and weather

Doesnt Perform Well In…

●Brake Fluids

●Ketones

●Hydrazine
