Fluorosilicone rubber has excellent oil resistance and solvent resistance, and is resistant to aliphatic, aromatic and chlorinated hydrocarbon solvents; various petroleum-based fuel oils, lubricants, hydraulic oils and certain synthetic oils (such as diester lubricants, Silicate hydraulic oil, etc.) have good stability at room temperature and high temperature, and can also maintain elasticity.

Fluorosilicone rubber properties:

Oil, solvent and chemical resistance
Compared with methyl vinyl silicone rubber, fluorosilicone rubber has extremely excellent oil resistance, solvent resistance, and chemical resistance; even compared with fluororubber, its oil resistance and solvent resistance are also good. It shows excellent durability after immersion in the same medium, temperature, and time. It can be said that fluorosilicone rubber is the only elastomer that can withstand non-polar media at -60°C to 260°C. Fluorosilicone rubber also has relatively good resistance to methanol-containing gasoline. Even in a gasoline/methanol mixed system, the hardness, tensile strength, and volume changes of its vulcanized rubber are very small. After a long 500-hour immersion test, various physical properties Very little has changed either.

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

cold resistance
Fluorosilicone rubber, like ordinary silicone rubber, has good low-temperature properties. Since fluorosilicone rubber is a linear polymer composed of soft Si-O as the main chain, its low temperature characteristics are better than those of fluororubber with C-C as the main chain. Among them, fluorosilicone rubber has better low-temperature characteristics, and its brittleness temperature can reach -59°C, while ordinary fluorosilicone rubber is about -30°C.

Physical and mechanical properties
Fluorosilicone rubber, like ordinary silicone rubber, can be made into conductive, antibacterial, flame retardant, and foaming fluorosilicone rubbers by optimizing the material formula design. On the basis of the original oil-resistant and solvent-resistant properties, it can increase conductivity, antibacterial, and Flame retardant, foaming and other properties.

Other features
Fluorosilicone rubber has excellent weather aging resistance and still maintains good performance even after 5 years of exposure. Ozone is one of the most generated gases when elastomers age. However, no cracks or cracks were found in fluorosilicone rubber after passing dynamic or static tests, and it has good ozone resistance. In addition, fluorosilicone rubber has very good mildew resistance, physiological inertness, and anticoagulant properties. Fluorosilicone rubber changes very little under harsh conditions such as high temperature, low temperature, moisture, oil, solvents, chemicals, and ozone. The radiation resistance of fluorosilicone rubber is not outstanding, but its radiation aging resistance is better than that of methyl vinyl silicone rubber.
