Fluorosilicone rubber O-ring O-shaped seal Because the main chain is a semi-inorganic silicone structure, it maintains the excellent properties of silicone materials such as heat resistance, cold resistance, high voltage resistance, weather resistance, etc. With the introduction of fluorine-containing groups, the fluorosilicone rubber ○ -ring ○ -shaped seal has excellent hydrogen-resistant solvents, oil resistance, acid and alkali resistance, and lower surface energy performance of organic fluorine materials. Fluorosilicone 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, the aircraft manufacturing industry is mainly used in the aviation industry to manufacture various types of sealing products (seals / contacts) that are resistant to fuel oil, lubricating oil, hydraulic oil, and solvents. Such as various dynamic and static working o-rings, fillers, overall tank seals, sealing rings, sensor materials, diaphragms, and fluorosilicone-clamped clamps. Valves, diaphragms, ducts, films, etc. used for pressure regulation of aviation films; such as diaphragms for valves in fuel tank pressure regulating pipes, diaphragms for fuel tank vent valves (kerosene vapor at -55 ° C to 200 ° C and 150 ° C Fluorine-silicone rubber coating used in RP kerosene and polyester cloth as the framework material); the fuel tank and piping system connection, liquid fluorosilicone rubber as the 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.
