Silicone oil, also known as polydimethylsiloxane, is an organic silicon compound with a silicone chain as the main skeleton and a methyl group or other organic group as the side chain. It has excellent physical and chemical stability.Due to its unique molecular structure, silicone oil can still maintain stable performance in complex environments such as high temperature, low temperature, electric field, heat and humidity, and is widely used in machinery, electronics, electric power, medical care, cosmetics and other fields.


In the field of lubrication, silicone oil is used in the manufacture of high-performance lubricants because of its high viscosity index, low coefficient of friction and excellent thermal oxidation stability, especially suitable for lubrication of high-temperature or high-speed operating equipment.Compared with mineral oils, silicone oils have a stronger affinity for metal surfaces, long-lasting lubrication, and are not volatile.In addition, silicone oil can also be combined with solid lubricants such as molybdenum disulfide and graphite to further improve lubrication performance.


In terms of electrical insulation, silicone oil has a very low dielectric constant and good electrical insulation properties. It is commonly used in the potting and cooling of transformers and electronic components, especially in high-voltage or high-frequency environments. It has superior performance.Its strong resistance to arc and corona can effectively extend the service life of electronic equipment.


Silicone oil also plays an important role in daily chemicals, such as softeners in skin care products and gloss agents in hair care.Medical-grade silicone oil is used for artificial vitreous filling, scar softener, etc., because of its high safety and non-allergy, it has been widely accepted.


It is worth mentioning that with the development of the concept of green manufacturing, new environmentally friendly silicone oil products have also emerged, such as low-volatile silicone oil, water-based silicone oil emulsions, etc., to meet higher standards of industrial and environmental protection needs.


In summary, silicone oil has become an indispensable functional material in modern industry due to its excellent multiple properties.In the future, with the integration of nano-modification, organic modification and other technologies, silicone oil will show great development potential in more high-end applications.
