Application fields of dimethyl silicone oil
Dimethyl silicone oil is a new synthetic liquid to semi-solid polymer compound with physiological inertness, good chemical stability, electrical insulation, high and low temperature resistance, softness and lubricity. It is widely used in many fields. The following is an introduction for you:
Industrial field
Mechanical and electrical industry: Dimethyl silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulating medium that is heat-resistant, arc-corona-resistant, corrosion-resistant, moisture-proof, and dust-proof. It can also be used as an impregnating agent for transformers, capacitors, and scanning transformers of televisions. In various precision machinery, instruments and meters, it can be used as a liquid shockproof and damping material.
Release agent: Due to the non-stickiness of dimethyl silicone oil with rubber, plastic, metal, etc., it can be used as a release agent for the molding and processing of various rubber and plastic products, as well as in precision casting.
Lubricant: Dimethyl silicone oil is suitable for lubricants for rubber, plastic bearings, and gears. It can also be used as a lubricant for rolling friction between steel and steel at high temperatures, or friction between steel and other metals. However, at room temperature, its lubrication performance is not particularly good, and it is generally not recommended as a lubricant between metals at room temperature.
Insulation, dustproof, and mildew-proof coatings: A layer of dimethyl silicone oil is applied to the surface of glass and ceramics, and after heat treatment at 250-300℃, a semi-permanent waterproof, mildew-proof and insulating film can be formed. It can be used to treat optical instruments to prevent lenses and prisms from mold; it can be used to treat medicine bottles to extend the shelf life of medicines and prevent the preparations from being lost due to wall adhesion; it can be used to treat the surface of film to lubricate, reduce friction, and extend the life of the film.
Additives: Adding a small amount of dimethyl silicone oil to coatings and inks can effectively reduce their surface tension and improve coating and expansibility.
Medical field
Defoaming effect: Dimethyl silicone oil is non-toxic to the human body and is not decomposed by body fluids. In medicine, its main use is its defoaming effect, which can reduce the amount of gas in the gastrointestinal tract. Taking dimethyl silicone oil during gastrointestinal endoscopy and various endoscopic surgical operations can reduce gas interference, which is conducive to clear vision and operation. Taking advantage of its defoaming effect, oral gastrointestinal detumescence tablets and pulmonary edema defoaming aerosols are also made for medicinal purposes.
Improve drug efficacy: Adding silicone oil to ointments can improve the drug's ability to penetrate the skin and improve drug efficacy. Treating the surface of the blood reservoir can extend the storage time of blood samples; some ointments based on silicone oil have good therapeutic effects on burns, dermatitis, bedsores, etc.
Daily chemical field
Cosmetics: Dimethyl silicone oil has good lubricity and smoothness. It can be used as a basic ingredient for cosmetics and personal care products to improve the texture of the product, making it easier to apply, extend and absorb. It can also help lock in moisture and maintain the moisture of the skin. For example, it can be used in a variety of cosmetic formulas such as skin care creams, shower gels, shampoos, etc. to provide a soft effect and silky feel, and can also be used as a defoaming agent for cosmetics.
Textile and clothing industry: Dimethyl silicone oil can be used as a softener, water repellent, feel improver, sewing thread lubrication, chemical fiber spinneret lubrication and clothing pressing lining aid, etc.; it can also be used as a water repellent, softener, feel improver for fibers and leather, as well as leather fatliquoring to enhance the hydrophobicity, softness and comfort of leather.
Food field
Defoamer: Dimethyl silicone oil can be used as a defoamer in food processing, such as fermentation process, to prevent the generation of foam in food processing.
Food additive: It can be used as a food additive to provide lubrication and anti-sticking functions. It can also be used to manufacture food packaging materials to improve its heat resistance and moisture resistance, ensure the quality and safety of food, and prevent adhesion between food and packaging materials.
Other fields
Heat carrier: Taking advantage of its high flash point, colorless, transparent and non-toxic to the human body, dimethyl silicone oil can be used as a heat carrier in oil baths or thermostats in industries such as steel, glass, and ceramics and scientific research.
Electronics Industry: Dimethyl silicone oil can be used as a packaging material for electronic components in the electronics industry to provide protection and insulation; it can also be used to manufacture optical lenses, displays and semiconductor equipment to provide dustproof and waterproof functions; in addition, it can also be used to manufacture coatings, adhesives and sealants to improve their weather resistance and adhesion properties.
