　　1. Application in the electromechanical industry

　　Dimethyl silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulation medium that is resistant to temperature, arc corona, corrosion, moisture, and dust. Currently, it is also used as an impregnating agent for transformers, capacitors, and scanning transformers in televisions. Used as a liquid shock-absorbing and damping material in various precision machinery, instruments, and meters. The shock absorption performance of dimethyl silicone oil is less affected by temperature and is commonly used in instruments with strong mechanical vibrations and large environmental temperature changes, such as aircraft and automotive instruments. Used for shock absorption, damping, stabilizing instrument readings, and can also be used as a liquid spring in aircraft landing gear.

　　2. As a defoamer

　　As a defoamer, dimethyl silicone oil has low surface tension and is insoluble in water, animal and vegetable oils, and high boiling mineral oils. It has good chemical stability and is non-toxic. It has been widely used as a defoamer in industries such as petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, and papermaking. As long as 10-100PPM of silicone oil is added, it has a good defoaming effect.

　　3. As a release agent

　　As a release agent, dimethyl silicone oil is not sticky with rubber, plastic, metal, etc., and is also used as a release agent for various rubber and plastic product molding processes, as well as in precision casting. Using it as a release agent not only facilitates demolding, but also makes the surface of the product clean, smooth, and with clear texture.

　　4. Apply insulation, dust-proof, and mildew proof coatings

　　Apply a layer of dimethyl silicone oil on the surface of glass and pottery as an insulation, dust-proof, and mildew proof coating. After heat treatment at 250-300 ℃, a semi permanent waterproof, mildew proof, and insulating film can be formed. Using it to treat insulating devices can improve their insulation performance: using it to treat optical instruments can prevent lens and prism from getting moldy; Using it to handle medication bottles can extend the shelf life of drugs without causing loss of the formulation due to wall sticking; Using it to treat the surface of film can provide lubrication, reduce friction, and extend the lifespan of the film.

　　5. As a lubricant

　　Dimethyl silicone oil is suitable as a lubricant for rubber, plastic bearings, and gears. It can also be used as a lubricant for rolling friction between steel at high temperatures, or for friction between steel and other metals. However, due to the poor lubrication performance of methyl silicone oil at room temperature, it is generally not recommended as a lubricant between metals at room temperature.

　　6. As an additive

　　Dimethyl silicone oil can be used as an additive for many materials, such as a gloss enhancer for paint. Adding a small amount of silicone oil to the paint can prevent it from floating or wrinkling, improve the brightness of the paint film. Adding a small amount of silicone oil to ink can improve printing quality. Adding a small amount of silicone oil to polishing oil (such as automotive varnish) can increase brightness, protect the paint film, and have excellent waterproof effect.

　　7. Application in healthcare

　　Dimethyl silicone oil has no toxicity to the human body and is not decomposed by body fluids, so it is widely used in medical and health care. By utilizing its defoaming effect, oral gastrointestinal bloating tablets and pulmonary edema defoaming aerosols have been developed for medicinal purposes. Adding silicone oil to ointment can enhance the drug's ability to penetrate the skin and improve its efficacy. Some ointments based on silicone oil have good effects on burns, dermatitis, bedsores, etc. By utilizing the anticoagulant effect of silicone oil, it can be used to treat the surface of blood reservoirs and extend the storage time of blood samples. It can also be used as a wet lubricant for condoms, and it does not kill sperm.

　　8. Fiber oil agent

　　In fiber preparation, especially in industrial carbon fiber production, modified dimethyl silicone oil is mainly used through amino modification, polyether modification, epoxy modification, etc. The modified dimethyl silicone oil has superior properties such as hydrophilicity, emulsification, and high temperature resistance. Currently, the research and development of modified silicone oil in China is relatively backward.

　　9. Other aspects

　　Dimethyl silicone oil has many other applications. For example, utilizing its high flash point, odorless, colorless, transparent, and non-toxic properties to the human body, it can be used as a heat carrier in industries such as steel, glass, ceramics, and scientific research as an oil bath or thermostat. Utilizing its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat artificial silk spinning heads can eliminate static electricity and improve the quality of silk drawing. Adding silicone oil to cosmetics can enhance its moisturizing and protective effects on the skin, among other benefits
