Silicone Fluid Have A Higher Heat Resistance
Aug 25, 2017

Silicone Fluid usually refers to a linear polysiloxane product that maintains a liquid state at room temperature. Generally divided into methyl silicone oil and modified silicone oil two categories. The most commonly used silicone oil monomethyl silicone oil, also known as ordinary silicone oil, the organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, hydrophobic performance. It is made by hydrolysis of dimethyldichlorosilane to obtain the initial polycondensation ring body, the ring by cracking, distillation made of low ring body, and then the ring body, the head agent, the catalyst together to get together to get the A mixture of different degrees of polymerization can be obtained by removing the low boiling matter by distillation under reduced pressure.

Silicone Fluid is generally colorless (or light yellow), tasteless, non-toxic, less volatile liquid. Silicone oil is insoluble in water, methanol, diol and -ethoxyethanol and can be miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, slightly soluble in acetone, dioxane, ethanol and butanol The It has a small vapor pressure, a higher flash point and a burning point, a lower freezing point.

Silicone Fluid has excellent heat resistance, electrical insulation, weatherability, hydrophobicity, physiological inertia and small surface tension, in addition to a low viscosity coefficient, high resistance to compression, and some varieties also have radiation resistance The performance.

Uses: There are a variety of different viscosities. High heat resistance, water resistance, electrical insulation and small surface tension. Often used as high-grade lubricants, shock oil, insulating oil, defoamers, release agent, polish, release agent and vacuum diffusion pump oil; emulsion can be used for automotive tire polishing, dashboard polishing. Methyl silicone oil is the most commonly used. After emulsification or modification after finishing in the textiles on the smooth soft touch finishing, daily care products in the shampoo also add emulsified silicone oil to improve the hair lubrication. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, silicone oil containing silicone, polyether modified silicone oil (water-soluble silicone oil) and so on.
