Performance of fluorosilicone: chemical resistance, solvent resistance and oil resistance. Compared with methyl vinyl silicone rubber, its performance is much better. At present, it is the only kind of non-polar elastomer resistant to fuel medium of - 68 ℃ ~ 232 ℃. Fluorosilicone also has good methanol gasoline resistance and almost no change in properties after 500h long-time impregnation. The heat resistance is slightly worse than that of ordinary silicone rubber.


Application of fluorosilicone: mainly in aerospace, electronic communications, vehicles and ships, precision instruments, petrochemical and medical and health fields. For example, aviation film in aviation equipment, integral fuel tank seal of aircraft, lining, seal, rubber gasket, rubber pipe caulking of integral fuel tank used for contacting with fuel oil and lubricating oil in petrochemical industry, rear sealing ring of automobile engine crankshaft, cylinder gasket, fuel pump seal, fuel tank cover gasket, filter seal, fuel pump diaphragm, etc
