Silicone oil is a polyorganosiloxane withdifferent degree of polymerization and chain structure. The most commonly usedsilicone oil is methyl silicone oil. Silicone oil is generally colorless (orlight yellow), tasteless, non-toxic, non-volatile liquid. Silicone oilinsoluble in water, methanol, diol and - ethoxy ethanol, with benzene, dimethylether, methyl ethyl ketone, carbon tetrachloride or kerosene miscible, slightlysoluble in acetone, dioxane, ethanol and alcohol . It has a very low vaporpressure, a high flash point and a flash point, and a lower freezing point. Withthe number of segments n, molecular weight increases, viscosity also increased,solid silicone oil can have a variety of different viscosities. Silicone oil bythe chemical structure to be divided into methyl silicone oil, ethyl siliconeoil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl siliconeoil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, Methylsilicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxyhydrogen silicone oil, cyanide-containing silicone oil, and the like;
From the use of points, there are dampingsilicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, heattransfer oil, brake oil. Silicone oil has excellent heat resistance, electricalinsulation, weatherability, hydrophobicity, physiological inertia and a smallersurface tension, in addition to a low viscosity-temperature coefficient, highresistance to compression) and some varieties also have radiation-resistantPerformance.
Silicone emulsion (a form of silicone oil)mainly silicone oil fabric softener; silicone emulsion defoamer: siliconedefoamer is the most widely used, the largest amount of a defoamer.
