Types of silicone oil
Silicone oil usually refers to a linear polysiloxane product that remains liquid at room temperature.
The structural formula is as follows: R is an alkyl group, an aryl group, R' is an alkyl group, an aryl group, a hydrogen, a carbon functional group, a polyether chain, etc.; X is an alkyl group, an aryl group, an alkenyl group, a hydrogen, a hydroxyl group, an alkane Oxy group, acetoxy group, chlorine v, carbon functional group and polyether chain, etc.; n, m=0, 1, 2, 3…
The most commonly used silicone oil, all organic groups are methyl, called methyl silicone oil. The organic group can also use other organic groups to replace part of the methyl group to improve certain properties of the silicone oil and apply to various uses. Common other groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and the like. In recent years, organo-modified silicone oil has developed rapidly, and many organo-modified silicone oils with special properties have appeared.
Silicone oil is divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, methyl trifluoropropane according to chemical structure. Base silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen-containing silicone oil, hydroxyl hydrogen-containing silicone oil, cyano-containing silicone oil, etc.; in terms of use, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, Heat transfer oil, brake oil, etc.
