Dimethicone is a colorless and transparent new synthetic polymer material with a variety of different viscosities (5cps to 8 million cps), from extremely fluid liquids to thick semi-solids. This product has special smoothness, softness, hydrophobicity, good chemical stability, excellent electrical insulation and high and low temperature resistance. It has high flash point and low freezing point, and can be used for a long time at -50℃～+200℃. It has small viscosity-temperature coefficient, high compressibility, low surface tension, good hydrophobicity and moisture resistance, and small specific thermal conductivity.

Dimethicone has various excellent properties, so it has been widely used in various departments of industrial and agricultural production, defense industry, scientific research and medical and health departments. It is widely used in electrical insulation, demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low humidity, etc.

1. Application in the electromechanical industry: Dimethicone is widely used in motors, electrical appliances, and electronic instruments as an insulating medium for temperature resistance, arc corona resistance, corrosion resistance, moisture resistance and dust resistance, as well as for transformers, capacitors, Impregnating agent for scanning transformers of TV sets, etc. It is used as liquid shockproof and damping material in various precision machinery, instruments and meters. The shock absorption performance of dimethyl silicone oil is less affected by temperature, and it is mostly used in instruments such as aircraft and automobiles in occasions with strong mechanical vibration and large changes in ambient temperature. For shock resistance, damping, stabilizing instrument readings, and also as a liquid spring, and in aircraft landing gear.

2. As a mold release agent: due to the non-stickiness of this product with rubber, plastic, metal, etc., it is also used as a mold release agent for the molding and processing of various rubber and plastic products, and in precision casting. Using it as a mold release agent is not only convenient for mold release, but also makes the surface of the product clean, smooth and clear in texture.

3. As a defoaming agent: due to its small surface tension and 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 defoaming agent in petroleum, chemical, In medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10-100PPM of silicone oil is added, it will have a good defoaming effect.

4. Insulation, dust-proof and mildew-proof coating: dip-coat a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treatment at 250-300 °C to form a semi-permanent waterproof and mildew-proof coating and insulating films. It is used to treat insulating devices, which can improve the insulation performance of the device: to treat optical instruments, it can prevent lenses and prisms from getting moldy; to treat medicine bottles, it can prolong the shelf life of drugs, and prevent the loss of preparations due to sticking to the wall; It can lubricate the surface of the film, reduce friction and prolong the life of the film. 1. Lubricant: This product is suitable to be used as lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for steel-to-steel rolling friction at high temperatures, or as a lubricant for steel and other metals. However, because methyl silicone oil has poor lubricating properties at room temperature, it is generally not recommended for use at room temperature. Intermetallic lubricant.

5. As an additive: This product can be used as an additive for many materials. For example, it can be used as a brightener for paint. Adding a small amount of silicone oil to the paint can make the paint not float and wrinkle to improve the brightness of the paint film. Add a small amount of silicone oil to the paint. In the ink, the printing quality can be improved. Adding a small amount of silicone oil to the polishing oil (such as car varnish) can increase the brightness, protect the paint film, and have an excellent waterproof effect.

6. Application in medical and health care: Dimethicone is non-toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health care. Utilizing its defoaming effect, the oral gastrointestinal defoaming tablet and the pulmonary edema defoaming aerosol have been prepared for medicinal purposes. Adding silicone oil to the ointment can improve the penetration ability of the drug into the skin and improve the efficacy of the drug. Some ointments based on silicone oil have good curative effects on scalds, dermatitis, bedsores, etc. Using the anticoagulant effect of silicone oil, it can be used to treat the surface of the blood reservoir and prolong the storage time of blood samples.

7. Other aspects: This product has many uses in other aspects. For example, using its high flash point, odorless, colorless, transparent and non-toxic to human body, it can be used as a heat carrier in oil baths or thermostats in steel, glass, ceramics and other industries and scientific research. Using its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat rayon spinning head can eliminate static electricity and improve the quality of spinning. Adding silicone oil to cosmetics can improve the moisturizing and protective effect of the skin and so on.
