Fluorosilicone

Fluorosilicone (FVMQ)

Fluorinated silicones provide chemical properties similar to those of fluorinated organic elastomers. This property provides excellent resistance to hydrocarbon fuels, petroleum oils and silicone fluids.

Fluorosilicones provide a much wider operational temperature range than fluorocarbon (FKM) elastomers -70°F to 400°F (-57°C to 205°C). Many applications for fluorosilicones are in synthetic oils, gasoline and even extended fuels since its low temperature performance is much better than that of FKM’s.
