Dimethyl silicone oil is also known as methyl silicone oil, polydimethylsiloxane liquid. It is an odorless, odorless, non-toxic, colorless, transparent, viscous liquid. Soluble in benzene, toluene, xylene, ethyl ether, partially soluble in ethanol, butanol, acetone, insoluble in cyclohexanol, methanol, paraffin oil, vegetable oil. It has excellent moisture resistance, good light transmission and chemical stability.


Use of dimethicone


Dimethicone is widely used in insulation, heat and moisture proof fillers, high efficiency defoamers, mold release agents, lubricants and surface treatment agents. The industries involved are daily chemical industry, rubber, plastics, latex and other industries, machinery, automotive, electronic appliances and other industries, clothing industry, leather industry, pharmaceutical industry, food industry and some new materials industries.


01
Daily chemical industry
It is used in a variety of cosmetic formulations such as skin creams, body washes, shampoos, etc. It has excellent softening effect and silky handfeel, which improves the moisturizing and protecting effect on the skin.


02
Plastic industry
Due to the non-stickiness of dimethyl silicone oil and rubber, plastic, metal, etc., it is used as a release agent, release agent and brightener in the production of certain rubber, plastic, latex, polyurethane products and handicrafts, so that the surface of the product is clean and smooth. Clear texture.


03
Machinery, automotive, electrical and other industries
Machinery, automotive, instrumentation, electronics and other industries, used as high-grade lubricants, liquid springs, cutting fluids, buffer oil, transformer oil, high and low temperature brake oil, brake oil, instrument damping oil, frame molding release agent, etc. . It can also be used as a liquid spring and in the landing gear of an aircraft.


04
Textile and garment industry
Used as softener, water repellent, hand feel improver, lubrication of sewing thread, lubrication of chemical fiber spinneret, garment press lining aid, defoamer, etc.


05
Leather and leather chemical industry
The leather and leather chemical industry will add this product to other additives, which can be used as softeners, water repellents, hand feel agents, defoamers, brighteners, etc.


06
Medicine, food
The pharmaceutical and food industries are used as defoamers and lubricants.
Dimethyl silicone oil is not toxic to human body and is not decomposed by body fluids. Therefore, it is widely used in medical and health care. Using its antifoaming effect, it has been made into oral gastrointestinal augmentation tablets, and pulmonary edema defoaming aerosols and the like. Adding silicone oil to the ointment can improve the penetration of the drug into the skin and improve the efficacy. Some pastes based on silicone oil have good effects on burns, dermatitis, hemorrhoids, etc.


07
Paint, ink and other industries
Can be used as a brightening agent for paint, add a small amount of silicone oil to the paint, so that the paint does not float, wrinkle, and improve the brightness of the paint film. Add a small amount of silicone oil to the ink to improve the printing 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 have excellent waterproof effect.


08
New materials industry
Used in other specific applications or copolymerized with other materials to form new materials




    Precautions   


Contact with high concentration of strong acid or strong base materials and Lewis acid has a tendency to degrade and volatilize. The higher the temperature, the more obvious the reaction. A low concentration of a strong acid or a strong base is in contact with it or a tendency to increase in viscosity until crosslinking occurs under high temperature for a long period of time.
