Application of dimethicone

  Dimethicone oil is a new synthetic liquid to semi-solid polymer compound, which is widely used in defoaming, electrical insulation, demoulding, painting, waterproof, dustproof, lubrication and other aspects due to its physiological inertness, good chemical stability, electrical insulation, high and low temperature resistance, flexibility and lubrication. In medicine, it mainly uses its defoaming effect, which can reduce the amount of gas in the gastrointestinal tract, and when performing gastrointestinal endoscopy and various endoscopic surgical operations, taking dimethicone oil can reduce the interference of gas, which is conducive to clear vision and operation.

Application of dimethicone

1. Application in mechanical and electrical industry: dimethicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulating medium for temperature resistance, arc resistance, corrosion resistance, moisture-proof, and dust-proof, and is also used as an impregnating agent for transformers, capacitors, and scanning transformers for televisions. In various precision machinery, instruments and meters, it is used as liquid shockproof and damping material.

2. As a defoamer: due to the small surface tension of dimethicone oil and insoluble in water, animal and vegetable oil and high boiling point mineral oil, good chemical stability and non-toxic, it has been widely used as a defoamer in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries.

3. As a release agent: due to the non-stickiness of dimethicone oil and rubber, plastics, metals, etc., it is also used as a release agent for the molding and processing of various rubber and plastic products, and is used in precision casting.

4. Insulating, dustproof and mildew-proof coating: a layer of dimethicone oil is impregnated on the surface of glass and ceramics, and a semi-permanent waterproof, mildew-proof and insulating film can be formed after heat treatment at 250~300 °C. It can be used to treat optical instruments to prevent mold on lenses and prisms; The treatment of the medicine bottle can prolong the shelf life of the drug and not make the preparation lose due to sticking to the wall; It can be used to treat the surface of motion picture film, which can play a lubricating role, reduce rubbing, and prolong the life of the film.

5. As a lubricant: dimethicone oil is suitable for making lubricants for rubber, plastic bearings and gears. It can also be used as a lubricant for steel-to-steel rolling friction at high temperatures, or when steel rubs against other metals.

6. As additives: dimethicone oil can be used as additives for many materials, such as brightening agent for paint, adding a small amount of silicone oil to the paint, which can make the paint not float and wrinkle to improve the brightness of the paint film, adding a small amount of silicone oil to the ink, adding a small amount of silicone oil to the polishing oil (such as car varnish), which can increase the brightness, protective film, and have excellent waterproof effect.

7. Application in medical and health care: Dimethicone oil is not toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health undertakings. Using its antifoaming effect, it has been made into oral gastrointestinal anti-swelling tablets, pulmonary edema and anti-foaming air cloud and other medicinal uses. The addition of silicone oil to the ointment can improve the drug’s ability to penetrate the skin and improve the efficacy

8. Other aspects: Dimethicone oil has many uses in other aspects. For example, by using its high flash point, non-existent, colorless, transparent and non-toxic to the human body, it is used as a heat carrier in oil baths or thermostats in industrial and scientific research such as steel, glass, ceramics, etc. It can be used to treat rayon spinning heads, which can eliminate static electricity and improve the quality of spinning. Adding silicone oil to cosmetics can improve the moisturizing and protective effect on the skin, etc.
