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.
