Methyl silicone oil is a type of linear polysiloxane polymer with excellent comprehensive performance, prepared through the hydrolysis and polycondensation of methyl chlorosilane monomers. It has outstanding chemical stability, thermal stability and hydrophobicity, and can maintain stable properties over a wide temperature range. It is also compatible with most organic solvents and lubricant additives, making it applicable in various industrial fields.
In terms of core functions, methyl silicone oil serves multiple roles in different scenarios, with the following key applications:
  1. High-performance lubricantIt has extremely low surface tension and good lubricity, and can form a uniform and stable oil film on the surface of metal, plastic and rubber materials. It is widely used as a lubricant for precision instruments, high-speed bearings and vacuum equipment, especially suitable for lubrication under extreme conditions such as high temperature, low temperature and high vacuum, where traditional mineral oils are difficult to meet the requirements.
  2. Heat transfer medium and temperature-resistant additiveWith its wide operating temperature range (usually from -50℃ to 200℃ or even higher), it can be used as a heat transfer oil in high-temperature heating or low-temperature cooling systems, ensuring efficient and stable heat transfer. When added to lubricants, it can improve the high-temperature resistance of the oil product, preventing oil oxidation and carbon deposition.
  3. Release agent and defoamerAs a release agent, it is widely used in the plastic and rubber processing industries, which can effectively prevent products from adhering to molds and ensure the smooth demolding of workpieces with high surface finish. In addition, its hydrophobicity and low surface tension make it an efficient defoamer, which can quickly eliminate foam in industrial fluids such as coatings, inks and water-based adhesives, and prevent foam regeneration.
  4. Electrical insulation materialIt has excellent electrical insulation performance, which is not affected by humidity and temperature changes. It is often used as an insulating oil for transformers, capacitors and other electrical equipment, improving the insulation reliability and service life of the equipment.
