Due to the stability of the siloxane bond and the hydrophobicity of the methyl group, as well as the structural characteristics of the methyl siloxane polymer, methyl silicone oil has good heat resistance. It has a high flash point, is not easily volatile, has a low viscosity coefficient, high compressive force, low surface tension, chemical stability, good electrical (insulation) properties, and is resistant to water and moisture. It has no toxic effects on organisms (including humans). In order to form a thin film or make a rubber-like solid substance on the surface of other objects, methyl silicone oil can be cured by heating at high temperatures (250-300°C) or with appropriate catalysts (usually peroxides). The use 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 presence in the low temperature field. First of all, let's take a look at the application of dimethyl silicone oil in low temperature lubrication. In cold environments, mechanical equipment, instrumentation, and electronic components often fail due to insufficient lubrication, but the emergence of dimethyl silicone oil provides a perfect solution for them. It can provide excellent lubrication performance at extremely low temperatures to ensure the normal operation of equipment.
 
01 Low temperature sealant
In addition to lubrication, dimethyl silicone oil can also be used as the first choice for low-temperature sealants. Due to its low viscosity and high chemical stability, it can prevent the leakage of gases and liquids at low temperatures. Whether in extremely cold weather or in industrial equipment in low-temperature environments, dimethyl silicone oil can provide reliable sealing and protect equipment from external environmental interference.
 
02 Low temperature coolant
In addition, dimethicone is also an excellent low-temperature coolant. It has excellent thermal conductivity and can effectively dissipate heat and maintain stable operating temperatures of equipment. Whether in electronic devices or in industrial production cooling systems, dimethicone can exert excellent cooling effects and ensure the normal operation of equipment.
 
In addition to the above applications, dimethyl silicone oil can also be used as vacuum pump oil, solvent and heat transfer medium in petrochemical processes, as well as preservatives and antioxidants for frozen foods. Its versatility and wide range of applications make dimethyl silicone oil an indispensable miracle in the field of cryogenics.
