Silicone oils generally refer to linear polysiloxane products that remain liquid at room temperature. It is generally divided into two types: methyl silicone oil and modified silicone oil. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, and good hydrophobicity. It is obtained by hydrolyzing dimethyl dichlorosilane with water to obtain the initial polycondensation ring body, and the ring body is cracked and rectified to obtain the lower ring body, and then the ring body, the head agent and the catalyst are put together to telomerize each Silicone oil can be obtained by removing low boilers from a mixture of different polymerization degrees by vacuum distillation.

Silicone oil usually refers to a linear polysiloxane product that maintains a liquid state at room temperature. The structural formula is as follows: In the formula, R is an alkyl group or an aryl group, and R' is an alkyl group, an aryl group, hydrogen, a carbon functional group, and a polyether chain, etc. ; X is alkyl, aryl, alkenyl, hydrogen, hydroxyl, alkoxy, acetoxy, chlorine v, carbon functional group and polyether chain, etc.; n, m=0, 1, 2, 3...

The most commonly used silicone oil, organic groups are all methyl, called methyl silicone oil. The organic group can also use other organic groups to replace part of the methyl group, so as to improve certain properties of silicone oil and apply to various purposes. Common other groups include hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl, and the like. In recent years, organo-modified silicone oils have developed rapidly, and many organo-modified silicone oils with special properties have emerged.

According to the chemical structure, silicone oil can be divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen-containing silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, methyl trifluoropropane Base silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxyl hydrogen silicone oil, cyanide silicone oil, etc.; in terms of application, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, Heat transfer oil, brake fluid, etc.

The high heat resistance, high flash point and low temperature fluidity of silicone oil make it very suitable for use as heat transfer oil. Dimethyl silicone oil can be used for a long time in the air at 175°C, methylphenyl silicone oil can be used for a long time at 200°C~250°C, and the maximum service temperature of SF series silicone oil can reach 425°C.
