These characteristics of dimethyl silicone oil make it widely used in various industrial fields. For example, it can be used as a defoamer, release agent, insulating coating, lubricant, etc. In terms of defoamers, due to its low surface tension and insoluble in water, dimethyl silicone oil is widely used in industries such as petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, and papermaking. In terms of release agents, due to its non-stickiness with materials such as rubber, plastic, and metal, dimethyl silicone oil has become an indispensable release agent in the molding and processing of various rubber and plastic products. In addition, dimethyl silicone oil can also form a waterproof, mildew-proof and insulating film on the surface of glass and ceramics through dipping and heat treatment, thereby improving the durability and safety of the product.

Dimethyl silicone oil performs well in low temperature environments, mainly in the following aspects:
1. Lubrication performance
In cold environments, mechanical equipment, instruments and electronic components may malfunction due to insufficient lubrication. Dimethyl silicone oil can provide excellent lubrication performance at extremely low temperatures, ensuring the normal operation of equipment and avoiding lubrication problems caused by cold13.
2. Sealing performance
Dimethyl silicone oil has low viscosity and high chemical stability, which enables it to effectively prevent gas and liquid leakage at low temperatures. Whether it is extremely cold weather or industrial equipment in low temperature environments, dimethyl silicone oil can play a reliable sealing role and protect the equipment from interference from the external environment.
3. Cooling performance
As an excellent low-temperature coolant, dimethyl silicone oil has excellent thermal conductivity, which can effectively dissipate heat and maintain a stable operating temperature of the equipment. This is especially important in cooling systems in electronic equipment and industrial production.
4. Chemical stability
Dimethyl silicone oil still maintains good chemical stability at low temperatures and has good resistance to the influence of climate, ozone and glow discharge. It is stable to water, air, oxygen, metal, wood, paper and plastic at room temperature, and is also stable to metal salt solutions, liquid ammonia and 3% hydrogen peroxide solution.
5. Electrical insulation performance
Dimethyl silicone oil has good electrical insulation performance and can still maintain good electrical strength and volume resistivity at low temperatures. This is of special significance to the electrical industry, especially in low temperature environments, its electrical insulation performance is still reliable.
In summary, dimethyl silicone oil not only maintains its original excellent performance at low temperatures, but also performs well in lubrication, sealing, cooling, chemical stability and electrical insulation. It is an indispensable and important material in the low temperature field.
