201 methyl silicone oil is a novel organosilicon synthetic material. Appearance is colorless and transparent oily liquid. Its chemical composition is straight-chain 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, the methylsiloxane oil has good heat resistance. Flashing light, non-volatile, small viscosity coefficient, large compressive force, small surface tension, chemical stability, good electrical (insulation) properties, and water and moisture resistance, non-toxic to living organisms (including humans). In order to make methyl silicone oil form a film on the surface of other objects or make a rubber-like solid substance, it can be cured by heating at a high temperature (250-300 ° C) or adding an appropriate catalyst (usually peroxide). The 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 into viscosity size, there are 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000 and other brands. Other products with special viscosity specifications can also be made according to user requirements.
