Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non-corrosive to metals, non-toxic, etc.. Due to these properties, silicone oil has excellent effect in many applications. Among all kinds of silicone oil, methyl silicone oil is the most widely used and the most important variety of silicone oil, followed by methyl phenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Properties: colorless, tasteless, non-toxic, non-volatile liquid.
Uses: There are various viscosities. It has high heat resistance, water resistance, electrical insulation and small surface tension. It is often used as high grade lubricant, anti-shock oil, insulating oil, defoamer, demoulder, polish, isolating agent and vacuum diffusion pump oil. Methyl silicone oil is most commonly used. After emulsification or modification, it is used in the finishing of textiles for smooth and soft hand finishing, and emulsified silicone oil is also added to the shampoo of daily care products to improve the lubricity of hair. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, silicone oil containing nitrile, etc.
Preparation or source: The oil is obtained by hydrolytic condensation of difunctional and monofunctional silicone monomers.
