What is dimethicone?
Methyl silicone oil is a novel organic silicone synthetic material. Appearance is colorless and transparent oily liquid. Its chemical composition is linear polymethylsiloxane, and its structural formula is:
Due to the stability of the silicon-oxygen bond, the hydrophobicity of the methyl group, and the structural characteristics of the methylsiloxane complex, methyl silicone oil has good heat resistance. It has a high flash point, is not volatile, has a small viscosity coefficient, a large compression force, a small surface tension, is chemically stable, has good electrical (insulating) properties, is water- and moisture-proof, and has no toxic effect on living organisms (including humans). In order to make methyl silicone oil form a thin film on the surface of other objects or make it into a rubber-like solid substance, it can be cured by heating at high temperature (250-300°C) or adding an appropriate catalyst (usually peroxide). The operating temperature range of methyl silicone oil is 50-180℃.
Methyl silicone oils with different viscosities also have certain differences in their physical and chemical properties and characteristic parameters. The product is divided by viscosity and has various grades such as 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000, etc. Products with other special viscosity specifications can also be made according to user requirements.
