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 FKMS (-57 to 205ºC; -70 to 400ºF). Many applications for fluorosilicones are in synthetic oils, gasoline and even extended fuels since its low temperature performance is much better than that of FKMS.
