Types of silicone oil
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.
