Silicone oil is a kind of polyorganosiloxane with chain structure with different polymerization degrees. The most commonly used silicone oil is methyl silicone oil. Silicone oil is generally colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Silicone oil is insoluble in water, methanol, glycol and-ethoxyethanol. It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It is slightly soluble in acetone, dioxane, ethanol and alcohol. . It has a small vapor pressure, a higher flash point and ignition point, and a lower freezing point. As the number of segments n is different, the molecular weight increases and the viscosity also increases. The solid silicone oil can have a variety of different viscosities. According to the chemical structure, 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, and methyl trifluoropropane. Silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxy hydrogen silicone oil, cyanide silicone oil, etc.; from the point of use, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, Heat transfer oil, brake oil, etc. Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. In addition, it also has a low viscosity-temperature coefficient and high compression resistance). Some varieties also have radiation resistance. Performance.

In terms of application, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, heat transfer oil, brake oil and so on. Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. In addition, it also has a low viscosity-temperature coefficient and high compression resistance). Some varieties also have radiation resistance. Performance.

Silicone emulsion (a form of silicone oil) mainly includes silicone oil fabric softening finishing agent; silicone oil emulsion type defoaming agent: it is the most widely used and the largest amount of silicone defoaming agent.
