Fluorosilicone rubber, also known as γ-trifluoropropyl methyl polysiloxane. Generally, 0.2% to 0.4% vinylsiloxane copolymerization modification is also introduced into the molecular chain. Colorless transparent high-viscosity plastic linear polymer compound. The main chain is composed of silicon and oxygen atoms. The side groups connected to silicon are methyl, vinyl and trifluoropropyl, and the molecular weight is between 500,000 and 800,000. With various additives, it can be mixed into a homogeneous rubber compound. Under the action of organic peroxides, it can be vulcanized into various elastic rubber products . In addition to the characteristics of general silicone rubber, it also has excellent resistance to aviation fuel oil, hydraulic oil, engine oil, chemical reagents and solvents. It can work for a long time at -55 ～ + 200 ℃. Because of its good performance, fluorosilicone O-rings are used in aviation, automotive and other fields.
FVMQ Fluorosilicone O-ring maintains the excellent properties of heat resistance, cold resistance, high voltage resistance, and weathering resistance of silicone materials. Due to the introduction of fluorine-containing groups, it also has excellent organic fluorine materials. Resistant to hydrogen solvents, oils, acids and alkalis, and lower surface energy properties.
