Silicone oil is generally divided into: methyl silicone oil and modified silicone oil

1) Methyl silicone oil refers to silicone oil in which all organic groups are methyl

2) Organic groups that use other organic groups instead of some methyl groups to improve the performance of silicone oil and are suitable for various purposes are collectively referred to as modified silicone oil. Common other functional groups include hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl, etc.

3) Silicone oil can be classified according to its chemical structure: 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 trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen containing silicone oil, hydroxyl hydrogen containing silicone oil, cyanide containing silicone oil, etc;

4) In terms of usage, it can be divided into: damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulation oil, heat transfer oil, brake oil, etc. The viscosity of silicone oil is not so sensitive to the type of silicone oil. Our common type of silicone oil is methyl silicone oil, and viscosity considerations are more common. The viscosity range of silicone oil is from 0.65cs to 400000cs. What determines the viscosity of silicone oil? Molecular weight! The degree of polymerization of silicone oil is related, and the larger the molecular weight, the higher the viscosity. Conversely, the smaller the molecular weight, the lower the viscosity. The corresponding production difficulty and cost will also be higher. The higher the viscosity of the corresponding silicone oil, the greater the low-temperature starting torque, and vice versa.
