Silicone Oil

Silicone Oil generally refers to silicone oil, and silicone oil is generally dimethyl silicone oil. It is a polyorganosiloxane with a chain structure of different degrees of polymerization. It is made by dimethyldichlorosilane hydrolysis to obtain the initial polycondensation ring, the ring body is cracked, refined to obtain a low ring body, and then the ring body, head capping agent, catalyst together can be mixed to obtain a variety of different degrees of polymerization, after reduced pressure distillation to remove the low boiling substance can be prepared to obtain silicone oil.

The most commonly used silicone oil, the organic group is all methyl, called methyl silicone oil. Organic groups can also be used with other organic groups instead of partial methyl groups to improve a certain performance of silicone oil and suitable for a variety of different uses. Common other groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and the like. In recent years, organic modified silicone oil has been rapidly developed, and many organic modified silicone oils with special properties have emerged.

Silicone oil has many special properties, such as small temperature and viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, small volatility, good insulation, small surface tension, non-corrosive to metals, non-toxic and so on. Because of these properties, silicone fluids have excellent results in many ways. Among the various silicone oils, methyl silicone oil is the most widely used and is the most important variety of silicone oil, followed by methylphenyl silicone oil. A variety of functional silicone fluids and modified silicone fluids are mainly used for special purposes.
Properties: colorless, tasteless, non-toxic and not easy to volatilize liquid.
Uses: There are a variety of different viscosities. It has high heat resistance, water resistance, electrical insulation and low surface tension. Commonly used as advanced lubricating oil, shock oil, insulating oil, defoamer, mold release agent, polishing agent, isolating agent and vacuum diffusion pump oil, etc.; Emulsion can be used for car tire glazing, instrument panel glazing, etc. Methyl silicone oil is the most commonly used. After emulsification or modification, it is used to smooth and soft finish on the textile finish, and emulsified silicone oil is also added to the shampoo of daily care products to improve the lubrication of hair. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, nitrile-containing silicone oil, polyether modified silicone oil (water-soluble silicone oil) and so on.
