Description

Fluorosilicone Rubber (FVMQ)

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.

Temperature Range:

Standard Low Temp: -60°C (-76°F)

Standard High Temp: 177°C (350°F)
