1. Application in the electromechanical industry: Dimethylsilicone 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 scanning transformers in transformers, capacitors, and televisions. Used as a liquid shock-absorbing and damping material in various precision machinery, instruments and meters. The shock-absorbing performance of dimethyl silicone oil is less affected by temperature, and it is mostly used in instruments such as aircraft and automobiles in situations with strong mechanical vibrations and large environmental temperature changes. Used for shock resistance, damping, and stabilizing instrument readings, it can also serve as a liquid spring and is used in aircraft landing devices.

3. As a defoamer: Due to its low surface tension and insolubility in water, animal and vegetable oils, as well as 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.
