Because the main chain is semi-inorganic silicone structure, it maintains the excellent performance of silicone materials such as heat resistance, cold resistance, high voltage resistance, climate aging resistance, etc. On the basis of the introduction of fluorinated groups, fluorine silicone rubber ○ ring ○ seal has excellent hydrogen solvent resistance and oil resistance of organic fluorine materials. Acid and alkaline resistance and lower surface energy properties. Fluorine silicone rubber O-rings can be widely used in aerospace, aviation, automotive, electric power, electronic appliances, textiles, machinery and construction and other fields. Take the space and automotive sectors for example.

1. Aerospace

In the aircraft manufacturing industry in the aerospace field, it is mainly used in the aviation industry to manufacture all kinds of sealing products (seals/contacts) that are resistant to fuel oil, lubricating oil, hydraulic oil, solvent, etc. Such as a variety of dynamic and static operation of the ○ ring, filler, integral fuel tank seal, sealing ring, sensor material, diaphragm, fluorine silicon liner clamp. Valves, diaphragms, conduits, films, etc. for aviation film pressure regulation; For example, the diaphragm of the valve in the tank pressure regulating pipeline and the diaphragm of the tank ventilation valve (the clip film of fluorosilicone rubber coating and polyester cloth as the skeleton material used in the kerosene steam of -55℃ ~ 200℃ and RP kerosene of 150℃); Fuel tank and pipeline system connection, liquid fluorine silicone rubber as surface coating agent, lubricant, sealing putty, adhesive and so on are also widely used.

With the requirements of the development of automobiles to high performance, low consumption, low emissions, low noise, low pollution and ultra-long service life and safety and comfort, automotive fuel oil, lubricants, refrigerants and other products are also constantly improving, especially the traditional rubber materials used in engines, transmission systems and fuel injection devices can not be applied to the use of new vehicles. Coupled with the increase in demand for high-end cars, the development of fluorosilicone rubber has brought opportunities.
