Fluorosilicone rubber O-ring O-shaped seal Because the main chain is a semi-inorganic silicone structure, it maintains the excellent performance of heat resistance, cold resistance, high voltage resistance, and weather resistance of silicone materials. With the introduction of fluorine-containing groups, the fluorosilicone rubber o-ring o-shaped seal has excellent hydrogen-resistant solvents, oil resistance, acid and alkali resistance, and lower surface energy performance of organic fluorine materials. Fluorosilicone rubber O-rings can be widely used in aerospace, aviation, automotive, power, electronics, textiles, machinery and construction. Let ’s take the example of fear of aerospace and automotive.
1. Aerospace industry
In the aerospace industry, in the aircraft manufacturing industry, it is mainly used in the aviation industry to manufacture various seal products (seals / contacts) that are resistant to fuel oil, lubricants, hydraulic oils, solvents, etc. Such as a variety of dynamic and static working o-rings, fillers, overall fuel tank seals, seal rings, sensor materials, diaphragms, fluorosilicone gasket clips, etc. Valves, diaphragms, ducts, films, etc. for the regulation and control of aviation film; for example, the diaphragm for the valve in the pressure regulating pipeline of the fuel tank, and the diaphragm for the valve of the fuel tank vent (kerosene vapor at -55 ℃ ～ 200 ℃ and 150 ℃ RP kerosene used in the fluoro-silicone rubber coating and polyester cloth as the framework material interlayer film); fuel tank and piping system connection, liquid fluorosilicone rubber as a surface coating agent, lubricant, sealing putty, adhesive Other uses are also very wide.
In the automotive industry
With the development of automobiles with high performance, low consumption, low emissions, low noise, low pollution, long service life and safety and comfort, products such as fuel oils, lubricants, and refrigerants for automobiles are continuously improved. In particular, the traditional rubber materials used in engines, transmission systems, and fuel injection devices have been unable to meet the requirements for the use of new automobiles. Coupled with the increase in demand for premium cars, the development of fluorosilicone rubber has brought opportunities.
