Because the main chain of the fluorosilicone rubber ○-ring ○-shaped seal is a semi-inorganic silicone structure, it maintains the excellent properties of the silicone material such as heat resistance, cold resistance, high voltage resistance, and weather aging resistance. With the introduction of fluorine-containing groups, the fluorosilicone rubber ○-ring ○-shaped seal has the excellent resistance to hydrogen solvents, oil resistance, acid and alkali resistance and lower surface energy properties of organic fluorine materials. Fluorosilicone rubber O-rings can be widely used in aerospace, aviation, automobiles, electric power, electronic appliances, textiles, machinery and construction and other fields. Let’s take the aerospace and automotive fields as examples.
1. Aerospace field.
In the aircraft manufacturing industry in the aerospace field, it is mainly used in the aviation industry to manufacture various sealing products (seals/contacts) that are resistant to fuel oil, lubricating oil, hydraulic oil, solvents, etc. Such as various dynamic and static working O-rings, fillers, integral tank seals, sealing rings, sensor materials, diaphragms, fluorosilicone gasket line clamps, etc. Valves, diaphragms, conduits, membranes, etc. used for aviation diaphragm pressure regulation; such as diaphragms for valves in fuel tank pressure regulating pipelines and diaphragms for fuel tank ventilation valves (kerosene vapor at -55°C ~ 200°C and 150°C The fluorosilicone rubber coating used in RP kerosene is sandwiched with polyester cloth as the skeleton material); the fuel tank and pipeline system are connected, and the liquid fluorosilicone rubber is used as a surface coating agent, lubricant, sealing putty, and adhesive It is also widely used.
In the automobile industry, with the development of automobiles towards high performance, low consumption, low emissions, low noise, low pollution, ultra-long service life, safety and comfort, automotive fuel oil, lubricating oil, refrigerant and other products are also With continuous improvement, especially the traditional rubber materials used in engines, transmission systems and fuel injection devices are no longer suitable for the use requirements of new cars. Coupled with the increase in demand for high-end cars, the development of fluorosilicone rubber has brought opportunities. The main products are: various vehicle sealing rings, oil seals, diaphragms, conduits, valve linings, etc. in the automotive industry; automotive fuel level indicator sensor hoses, oil guide tubes, atomizer oil pump diaphragms, fuel pump diaphragms, corrugated sheaths, engine crankshafts Rear sealing ring, cylinder gasket, fuel pump seal, fuel tank cap gasket, fuel tank refueling gasket, cylinder gasket, oil filter seal, vacuum adjustment diaphragm, rubber ring
