（1） Application in industry
Electrical insulation and shock resistance
Methyl silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulation medium that is resistant to temperature and arc corona. It is also used as an impregnating agent for transformers and capacitors, as well as a filling material for instrument panels, which can effectively prevent vibration, damping, and stabilize instrument readings.


Release agent
The non adhesiveness of methyl silicone oil makes it an ideal release agent, widely used in the molding and processing of rubber and plastic products, as well as precision casting. It can make the surface of the product smooth, with clear texture, and easy demolding.


Defoamer
Due to its low surface tension and chemical stability, methyl silicone oil is widely used in industries such as petroleum, chemical, food processing, textile, printing and dyeing as an efficient defoamer.


lubricant
Methyl silicone oil has good lubricity and is suitable for lubricating rubber, plastic bearings, and gears. It can also be used as a lubricant for metal friction at high temperatures.


（2） Application in the field of architecture and waterproofing
Methyl silicone oil is often used as a waterproofing agent in the construction industry, which can effectively prevent moisture from seeping into building materials and reduce damage to buildings. In addition, it can also be used as a concrete additive to improve the fluidity and frost resistance of concrete.


（3） Application in healthcare
Methyl silicone oil is harmless to the human body and is not decomposed by body fluids, so it is widely used in the medical and health field. For example, it can be used for lubrication and anti mold treatment of medical devices, and can also be used as an anti adhesive agent for drug packaging.


（4） Future Development Trends
With the advancement of technology, the application scope of methyl silicone oil will further expand, especially in the fields of new energy and environmental protection. For example, it can be used as a waterproof coating for solar panels or as an insulation material for electric vehicle batteries.
