Fluorosilicone O-Ring (FMVQ) Material Description
Fluorosilicone (FVMQ) is like side chains of silicone rubber, bonding trifluoropropyl, methyl and vinyl. The mechanical and physical properties are similar to VMQ. However, FVMQ offers improved fuel and mineral oil resistance, but less hot air resistance than standard VMQ.
Cure system: Peroxide-cured
Standard FVMQ compounds are metal peroxide-cured.
Fluorosilicone O-Ring Temperature Range:
Standard Low Temp: -60°C (-76°F)
Standard High Temp: 177°C (350°F)
