High temperature lubrication performance
Silicone oil, especially dimethyl silicone oil, is a kind of lubricating oil with excellent performance.It takes polydimethylsiloxane as the main body, and has the characteristics of low viscosity, good fluidity, strong shear resistance, and not easy to oxidize.These characteristics allow silicone oil to maintain stable lubrication performance in high temperature environments.Dimethyl silicone oil can be used continuously in a wide temperature range of -50 to 200℃, and some types can even be used for a long time at 250℃, demonstrating its excellent high temperature stability.Therefore, silicone oil is often used as a lubricant for various mechanical equipment, such as automobile engines and gearboxes, as well as high-temperature hydraulic oils, transformer filling oils, etc.


In contrast, although silicone resin also has certain lubricating properties, its main purpose is not lubrication.Silicone resin is a kind of polymer solid, usually mixed with silicone rubber, diatomaceous earth, etc., mainly used in mold making, sealing materials, coatings, toughening agents, etc.Although silicone resin can remain stable under high temperature conditions and is not easy to age, its lubricating properties are not as prominent as silicone oil.


Insulation properties
In terms of insulation properties, both silicone resin and silicone oil have shown excellent properties.Silicone resin has excellent insulation properties, heat resistance and chemical stability, and can still maintain good insulation properties under high temperature, high humidity and high electric field conditions.This makes silicone resin widely used in electronics, aviation and other industrial fields, as insulation materials, packaging materials, coatings and adhesives.


Silicone oil also has outstanding electrical insulation properties.Dimethyl silicone oil is non-toxic and odorless, has extremely high transparency, and exhibits excellent electrical insulation properties and heat resistance.It can be used as an insulating medium for electrical equipment and is widely used in transformers, cables and other electrical installations.In addition, silicone oil also has good waterproof and anti-corrosion properties, which further enhances its application advantages in the field of insulation.


Silicone oil and silicone resin have their own merits in terms of high temperature lubrication and insulation properties.Silicone oil occupies an important position in the field of lubrication because of its excellent high temperature stability and lubrication properties; while silicone resin is widely used in electronics, aviation and other industrial fields because of its excellent insulation properties, heat resistance and chemical stability.In practical applications, suitable materials should be selected according to specific needs and working environment.
