silicone is a different degree of polymerization of the polysiloxane chain structure. The most commonly used silicone oil is methyl silicone oil. Silicone is generally colorless ( or light yellow ), tasteless, non-toxic, non volatile liquid. Silicone is not soluble in water, methanol, glycol and ethylene glycol, miscible with benzene, two ether, methyl ethyl ketone, carbon tetrachloride or kerosene, slightly soluble in acetone, dioxane two, ethanol and alcohol. It has the freezing point of a very small vapor pressure, high flash point and ignition, lower. With the chain segments of the different N, the molecular weight increases, viscosity also increased, therefore can have a variety of silicone oil viscosity. According to the chemical structure of silicone oil into methyl silicone oil, silicone oil, silicone oil, ethyl phenyl methyl silicone oil containing hydrogen, methyl phenyl silicone oil, methyl chloride, methyl phenyl silicone oil, silicone oil, ethoxylated methyl three fluorine propyl silicone oil, methyl vinyl silicone oil, methyl ethyl hydroxy silicone oil, silicone oil containing hydrogen, hydroxyl silicone oil containing hydrogen, cyanide containing silicone oil; from the use of points, a damping silicone oil, silicone oil diffusion pump, hydraulic oil, insulating oil, heat transfer oil, brake oil. Silicone oil with surface tension of electric heat, excellent insulation, weather resistance, hydrophobicity, physiological inert and smaller, moreover also has the temperature coefficient of viscosity, high and low resistance to compression) and some varieties resistant to radiation performance.

Silicone emulsion ( is a form of silicone oil ) with silicone fabric softening agent; silicone emulsion type defoaming agent: silicone defoamer used most widely, the largest amount of a defoaming agent.
