FVMQ, as their name suggests, have similar polymer structure as VMQ, but with the additional trifluoropropyl substituent group on the polymer chain (yellow frame). This extra substituent gives the end product excellent resistance to many fuels (aliphatic and aromatic), solvents (benzene, toluene, ..), oils (animal, vegetable, mineral, silicone, …) and chemicals which would severely degrade VMQ and most other polymers.
The mechanical and physical properties are very similar to VMQ. However, FVMQ offer poor hot air resistance when compared with VMQ. Compared to Fluorocarbon rubbers fluorosilicones provide a much wider operational temperature range as they can reach temperatures up to 175°C and go as low as -70°C. In some cases, however, high temperature range in fluids is limited due to possible degradation of fluid and formation of harmful acids.
FVMQ Is for example used in:
