More About FVMQ

Fluorosilicone was invented by Dow Corning in the early 1950’s. The international nomenclature for fluorosilicone rubber is FVMQ.

FVMQ polymers are built of polysiloxane chains where methyl side groups are replaced by trifluoropropyl side groups. Therefore they have nearly the same mechanical and physical properties as silicone rubber but due to the fluorination they show better resistance against many fluids.

FVMQ polymers typically contain 23-28 % Fluor. FVMQ has a good heat resistance, very good low temperature flexibility and excellent resistance to weather, ozone and UV rays. Compared to VMQ the temperature range is slightly reduced from -50°C to 180°C.

The main applications for this material are injectors for CNG and quick connectors for fuel rails.
