Characteristics and Applications of Dimethyl Silicone Oil
Dimethyl silicone oil, as a colorless, odorless, and non-volatile organic silicon material, has demonstrated its unique value and broad application prospects in multiple fields. This polymer compound not only has excellent heat resistance, electrical insulation, and weather resistance, but also has good hydrophobicity, physiological inertness, and low surface tension.

Dimethyl silicone oil has stable chemical properties and is insoluble in water, methanol, and ethylene glycol, but can be miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride, or kerosene. Its unique physical properties, such as low viscosity temperature coefficient and high compression resistance, make dimethyl silicone oil excellent in insulation lubrication, shock resistance, oil dust prevention, dielectric fluid and heat carrier.


In the electromechanical industry, dimethyl silicone oil is widely used as an insulation medium for motors, electrical appliances, electronic instruments, as well as an impregnating agent for equipment such as transformers and capacitors. Its characteristics of temperature resistance, arc corona resistance, corrosion resistance, moisture resistance, and dust prevention make it an indispensable component of these devices. In addition, dimethyl silicone oil can also be used as a release agent for rubber and plastic product molding and processing, as well as a lubricant in precision casting.


In the medical field, the defoaming effect of dimethyl silicone oil is widely used. It can reduce the amount of gas in the gastrointestinal tract, making gastroscopy and various endoscopic surgical procedures clearer and smoother. At the same time, dimethyl silicone oil can also be used to make oral gastrointestinal bloating tablets, as well as medicinal products such as pulmonary edema defoaming aerosols.


In addition, dimethyl silicone oil has a wide range of applications in daily chemical, food, construction and other fields. Its non-toxic, odorless, and physiologically inert properties make it an ideal additive and lubricant in these fields.
