Fluorosilicone Elastomer (Fluorosilicone Gel) is a kind of synthetic materials based on polymethyltrifluoropropylsiloxane. The condensation type is usually hydroxyl-terminated, while the addition type is mixed with a certain amount of unsaturated olefins. The molecular weight of room-temperature vulcanized fluorosilicone elastomer is relatively small, ranging from 1×104 to 8×104, while the high-temperature vulcanized type can reach 4×105 to 8×105. 

Fluorosilicone rubber can be obtained by vulcanizing fluorosilicone elastomer with vulcanizing agent and various reinforcing fillers. Fluorosilicone elastomer combines the oil & solvent resistance and chemical resistance of fluorocarbon rubber with the excellent properties of low temperature softness and high tensile retention rate at high temperature of silicone rubber. 

The rubber parts made of fluorosilicone rubber can keep enough elasticity even at the temperature below 55℃. When the temperature is high, they can also be used for a long time. In addition, fluorosilicone rubber has excellent resistance to fuel oil, lubricating oil and chemicals. It is an elastic material with comprehensive properties, its performance is reliable and durable. It is widely used in aerospace, transportation, petrochemical, medical and health industries.
