Silicone oil, also known as polysiloxane, is an organic silicon compound with a silicon-oxygen bond as the main chain, which has excellent physical and chemical properties and wide application value.It is commonly found in a transparent liquid state, with a viscosity ranging from a few centimetres to millions of centimetres, and can be adjusted as needed.Silicone oil has good thermal stability, electrical insulation, hydrophobicity and physiological inertness, so it is widely used in many fields such as industry, medicine, daily chemicals and electronics.


Structurally, silicone oils are divided into straight-chain and modified types.Straight-chain polydimethylsiloxanes are the most common type. They have high stability, are not easy to oxidize, and are not easy to react with other chemicals.Modified silicone oil introduces specific functional groups, such as amino groups, hydroxyl groups, etc., on the main chain to give it more functions, such as better adhesion or hydrophilicity.


In industrial manufacturing, silicone oil is used as a lubricant, mold release agent and insulating oil.It is not easy to degrade in high temperature environments, and is particularly suitable for use in machining, electrical installations, and aircraft materials.The pharmaceutical industry uses its physiological inertness to prepare ointments, artificial vitreous bodies, etc.In the field of daily chemicals, silicone oil is used as a softener in conditioners and skin care products to enhance the feel and gloss of products.


With the continuous development of science and technology, the functionality of silicone oil is also constantly expanding.For example, through chemical modification, advanced functions such as self-emulsification and hydrophilic and oleophilic balance control can be realized, and its application in cutting-edge fields such as new materials and biomedical materials can be further promoted.


In short, silicone oil, as a kind of silicone material with excellent performance, has shown an irreplaceable position in many industries.In the future, with the increase of functional demand, the research and development and application of silicone oil will continue to deepen, promoting the development of more high value-added products.
