Dimethicone has a variety of excellent characteristics, so it has been widely used in various sectors of industrial and agricultural production, defense industry, scientific research, medical and health departments. It is widely used in electrical insulation, demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low humidity.
1. Dimethicone uses in the electromechanical industry
Dimethicone is widely used in electric motors, electrical appliances and electronic instruments as an insulating medium for temperature resistance, arc resistance, corrosion resistance, moisture resistance and dust resistance. It is also used as an impregnating agent for transformers, capacitors, and scanning transformers of televisions. Used as a liquid shockproof and damping material in various precision machinery and instruments. The vibration-absorbing performance of dimethicone is less affected by temperature, and it is often used in places with strong mechanical vibration and large changes in ambient temperature. It is used for shockproof, damping, and stable meter readings. It can also be used as a liquid spring in aircraft landing gear.
2. Dimethicone uses as a release agent
Because this product is not sticky with rubber, plastic, metal, etc., it is used as a release agent for various rubber and plastic products, and used in precision casting. By using it as a release agent, it is not only easy to demould but also makes the surface of the product clean, smooth and clear.
3. Dimethicone uses as a defoamer
Due to its small surface tension, insolubility in water, chemical stability and nontoxicity in animal and vegetable oils and high-boiling mineral oils. It has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries as a defoaming agent. As long as 10-100 PPM of silicone oil is added, it has a good defoaming agent. As long as 10-100 PPM of silicone oil is added, it has a good antifoaming effect.
4. Dimethicone used as insulation, dustproof, mildew resistant coating
A layer of dimethyl silicone oil is applied to the surface of the glass and ceramics, and after heat treatment at 250-300 ° C, a semi-permanent waterproof, mildewproof and insulating film can be formed. Using it to treat the insulating device can improve the insulation performance of the device; It can be used to process optical instruments to prevent mold and prisms from becoming moldy; Treating the vial with it can prolong the shelf life of the drug without causing the formulation to be lost due to sticking; It is used to treat the surface of cine film, which can lubricate, reduce friction and extend the life of the film.
5. Dimethicone uses as a lubricant
This product is suitable for rubber, plastic bearings, gears as lubricants. It can also be used as a lubricant for rolling friction of steel against steel at high temperatures, or when steel is rubbed against other metals. However, since the lubricating property of methyl silicone oil is not particularly good at normal temperature, it is not recommended as a lubricant between metals at normal temperature.
6. Dimethicone uses as an additive
This product can be used as an additive for many materials. For example, it can be used as a brightening agent for paints. Add a small amount of silicone oil to the paint to make the paint not float, wrinkle and improve the brightness of the paint film; Add a small amount of silicone oil to the ink to improve print quality; Add a small amount of silicone oil to the polishing oil (such as automotive varnish) to increase the brightness, protect the paint film, and make it has excellent waterproof effect.
7. Dimethicone uses in medical and health
Dimethicone is not toxic to the human body and is not decomposed by body fluids. Therefore, it is widely used in medical and healthcare. By utilizing its antifoaming effect, it has been made into oral gastrointestinal swelling tablets, and pulmonary edema defoaming aerosols and the like. Adding silicone oil to the ointment can improve the penetration ability of the drug and improve the efficacy. Some pastes based on silicone oil have a good curative effect on scald, dermatitis and hemorrhoids. The anticoagulant effect of silicone oil can be used to treat the surface of the blood reservoir and prolong the storage time of the blood sample.
8. Dimethicone uses As a heat carrier
This product has many other uses in other areas. For example: because of its characteristics of a high flash point, odorless, colorless, transparent and non-toxic to the human body, it can be used as a heat carrier in oil baths or thermostats in industries such as steel, glass, ceramics, etc.
9. Dimethicone uses As a hydraulic oil
With its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil.
10. Dimethicone uses As a rayon spinning head
It can eliminate static electricity and improve the quality of spinning.
11. Dimethicone uses in cosmetics
The addition of silicone oil can enhance the moisturizing and protective effects on the skin.
The above is part of dimethicone uses.
