201 methyl silicone oil is a novel organic silicon synthetic material. The appearance is a colorless and transparent oily liquid. Its chemical composition is linear polymethylsiloxane.
Due to the stability of the silicon-oxygen bond and the hydrophobicity of the methyl group, as well as the structural characteristics of the methyl siloxane polymer, the methyl silicone oil has good heat resistance. It has bright flashing light, low volatility, low viscosity coefficient, high compressive force, low surface tension, stable chemical properties, good electrical (insulation) properties, water and moisture resistance, and non-toxic effects on 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 heated at a high temperature (250-300°C) or added with an appropriate catalyst (usually peroxide) for curing. The use temperature range of methyl silicone oil is 50-180°C.
Methyl silicone oils with different viscosities have certain differences in their physical and chemical properties and characteristic parameters. The product is divided into various grades according to the viscosity, such as 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, and 201-1000. It can also be made into products with other special viscosity specifications according to user requirements.
