Silicone Fluid is a polyorganosiloxane with different degree of chain structure of degree of polymerization. The most commonly used silicone oil is methyl silicone oil. Silicone oil is generally a colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Silicone oil is insoluble in water, methanol, diols, and ethoxyethanol. It is soluble in benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride, or kerosene. It is slightly soluble in acetone, dioxane, ethanol, and alcohols. . It has a small vapor pressure, a high flash point and flash point, and a low freezing point. With the difference in the number of segments n, the molecular weight increases, and the viscosity also increases, so that the silicone oil can have a variety of different viscosities. According to the chemical structure of silicone oil 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 silicon oil, methyl trifluoromethane Silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxy hydrogenated silicone oil, cyanide-containing silicone oil, etc.;
Divided from the use, 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 inertness and small surface tension, in addition has a low viscosity temperature coefficient, high compression resistance) Some varieties also have radiation resistance Performance.
Silicone emulsion (a form of Silicone Fluid) is mainly a silicone oil fabric softening agent; silicone oil emulsion type defoamer: It is an antifoaming agent with the widest surface and the largest amount of silicone defoamers.
