Due to the stability of the silicon-oxygen bond and the hydrophobicity of the methyl group, as well as the structural characteristics of the methylsiloxane polymer, methyl silicone oil has good heat resistance. It has a high flash point, is not easy to volatilize, has a low viscosity coefficient, a large compression force, a small surface tension, is chemically stable, has good electrical (insulating) properties, is water-resistant and moisture-proof, and has no 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 a rubber-like solid substance, it can be heated at high temperature (250-300°C) or cured with an appropriate catalyst (generally peroxide). The operating temperature range of methyl silicone oil is 50-180°C.

Dimethyl silicone oil is a widely used lubricant and heat transfer medium for low temperature applications. Its low temperature performance and thermal stability make it an indispensable existence in the low temperature field. First, let's take a look at the application of dimethyl silicone oil in low temperature lubrication. In cold environments, mechanical equipment, instruments and electronic components often fail due to insufficient lubrication, and the emergence of dimethyl silicone oil provides them with a perfect solution. It can provide excellent lubrication performance at extremely low temperatures to ensure the normal operation of the equipment.
