Oil resistance, solvent resistance, chemical resistance fluorine silicone rubber compared with methyl vinyl silicone rubber, its oil resistance, solvent resistance, chemical resistance is very good; Even compared with fluorine rubber, oil resistance and solvent resistance are good. After dipping in the same medium, temperature and time, it shows excellent durability, and it can be said that fluorosilicone rubber is the only elastomer resistant to non-polar media at -60 ° C ~ 260 ° C. The resistance of fluorine silicone rubber to methanol containing gasoline is also relatively good, even in the gasoline/methanol mixed system, the hardness, tensile strength, volume changes of its vulcanized rubber are very small, after 500h long time impregnation test, the physical properties are almost unchanged.

The high temperature resistance of fluorine silicone rubber is the same as that of silicone rubber, which can be significantly improved by adding a small amount of heat stabilizer such as iron, titanium and rare earth oxides, and has sufficient heat resistance even at 250 ° C high temperature. The influence of temperature on fluorine silicone rubber is greater than that of silicone rubber.

Cold-resistant fluorosilicone rubber and ordinary silicone rubber, low temperature performance is good. Because fluorine silicone rubber is a linear polymer composed of soft Si-O main chain, the low temperature characteristics are better than fluorine rubber with C-C main chain. Among them, fluorine silicone rubber has better low temperature characteristics, and the brittle temperature can reach -59 ° C, while the general fluorine rubber is about -30 ° C.

Physical and mechanical properties fluorine silicone rubber and ordinary silicone rubber, you can optimize the material formula design, make conductive type, antibacterial type, flame retardant type, foaming type fluorine silicone rubber, on the basis of the original oil resistance and solvent resistance, increase the conductivity, antibacterial, flame retardant, foaming and other characteristics.
