Fluorosilicone, similar to silicone rubber, bonding trifluoropropyl, methyl and vinyl as side chains. Fluorosilicone’s Physical and mechanical properties are similar to the ones of standard VMQ. FVMQ however, offers increased resistance towards fuel and mineral oils. FVMQ’s hot air resistance is poorer than standard VMQ.
Actum Sweden AB has its own FVMQ compounds: F7004BU02, F3002BU
|UL||-55~80°C||F7004BU02||FVMQ||70±5 Shore A||Blue|
|UL1238||UL||-40~60°C||F3002BU||FVMQ||30±5 Shore A||Blue|
Standard FVMQ compounds are peroxide cured.
Since FVMQ offers excellent low-temperature flexibility and good resistance to fuel and aromatic mineral oils it is often used together with jet and automotive fuels, most solvents and engine oil especially in aerospace industry.
