Fluorosilicone rubber has excellent oil and solvent resistance properties, for aliphatic, aromatic and chlorinated hydrocarbon solvents; various petroleum-based fuel oils, lubricating oils, hydraulic oils and some synthetic oils (such as diester lubricating oils, 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 excellent oil resistance, solvent resistance and chemical resistance; even compared with fluororubber, oil resistance and solvent resistance are also good. It shows excellent durability after being immersed in the same medium, temperature and time. It can be said that fluorosilicone rubber is the only elastomer that is resistant to non-polar medium at -60℃～260℃. The fluorosilicone rubber has good resistance to methanol-containing gasoline. Even in the gasoline/methanol mixed system, the hardness, tensile strength and volume of the vulcanizate change very little. After 500h long-time immersion test, the physical properties There is also little change.

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, and it has sufficient heat resistance even at a high temperature of 250 °C. . The effect of temperature on fluorosilicone rubber is greater than that of silicone rubber.

cold resistance

Like ordinary silicone rubber, fluorosilicone rubber has good low temperature performance. Since fluorosilicone rubber is a linear polymer composed of soft Si-O as the main chain, its low-temperature properties are better than that of fluororubber with C-C as the main chain. Among them, fluorosilicone rubber has better low temperature characteristics, and the brittle temperature can reach -59℃, while the general fluororubber is about -30℃.

physical and mechanical properties

Like ordinary silicone rubber, fluorosilicone rubber can be made into conductive, antibacterial, flame retardant and foamed fluorosilicone rubber by optimizing the material formula design. Flame retardant, foaming and other characteristics.

                                                               Other features

Fluorosilicone rubber has excellent weathering resistance and maintains good performance even after 5 years of exposure. Ozone is one of the most generated gases when the elastomer is aging, but the fluorosilicone rubber has no cracks or cracks after dynamic or static tests, and has good ozone resistance. In addition, fluorosilicone rubber is also very good in mildew resistance, physiological inertness, and anticoagulation. Fluorosilicone rubber has little change under harsh conditions such as high temperature, low temperature, humidity, oil, solvent, chemicals, and ozone. The radiation resistance of fluorosilicone rubber is not outstanding, but the radiation aging resistance is better than that of methyl vinyl silicone rubber.

Fluorosilicone rubber product application

1. Aviation industry: seals and contact parts of fuel oil and lubricating oil on aircraft, such as various O-rings, gaskets, sealing rings, sensor materials, diaphragms, and wire clips for fluorosilicon gaskets, and can also be used for aircraft fuel tanks the overall seal.

2. Automobile industry: turbocharger pipes for various types of vehicles, sealing rings, oil seals, diaphragms, conduits, valve linings, etc.

3. Medical and health care: used for medical devices and artificial organs, such as medicinal catheters, drainage tubes, artificial valves, etc.

4. Military industry: It is used in harsh environments requiring low temperature resistance, oil resistance and acid resistance, such as the hydraulic system infusion bellows of military aircraft, doors and windows of special vehicles, rear cover sealing strips, and sensing materials for sensors.

5. Petrochemical: all kinds of high temperature, low temperature, chemical corrosion resistant pumps, valves, oil tanks and other equipment seals.
