Dimethyl silicone oil, also known as methyl silicone oil, polydimethyl siloxane liquid. Is a tasteless, 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 transmittance and chemical stability.
Use of dimethyl silicone oil


Dimethyl silicone oil is widely used as filler for insulation, heat resistance and moisture resistance, high-efficiency defoaming agent, mold release agent, lubricant and surface treatment agent. The industries involved include daily chemical industry, rubber, plastic, latex and other industries, machinery, automobile, electronics and electric appliances, clothing industry, leather industry, medicine industry, food industry and some new materials industry.
Daily chemical industry
Used for skin care cream, body lotion, shampoo and other cosmetics formula, with excellent soft effect and silky feel, improve the moisturizing and protecting effect on skin, etc.


02
Plastic industry
Because of its non-viscosity with rubber, plastic and metal, dimethyl silicone oil is used as the release agent, isolating agent and brightening agent in the production of some rubber, plastic, latex, polyurethane products and handicrafts, making the surface of products clean, smooth and clear.


03
Machinery, automotive, electrical and other industries
It is used as high-grade lubricating oil, liquid spring, cutting fluid, buffer oil, transformer oil, high and low temperature brake oil, brake oil, instrument shock absorbing oil, frame molding release agent and so on. It can also be used as a liquid spring and in the landing device of aircraft.


04
Textile and garment industry
Used as softener, hydrophobic agent, hand feel improver, sewing thread lubrication, chemical fiber spinneret lubrication and clothing pressure lining assistant, defoaming agent, etc.


05
Leather and leather chemical industry
Leather and leather chemical industry will add this product to other additives, can be used as softener, detest agent, feel agent, defoaming agent, brightener and so on.


06
Medicine, food
Pharmaceutical, food industry used as defoaming agent, lubricant, etc.
Dimethyl silicone oil has no toxicity to human body and is not decomposed by body fluids, so it is widely used in medical and health care. With its antifoaming effect, oral gastrointestinal antidistention tablets and pulmonary edema antifoaming aerosol were prepared. Adding silicone oil in the ointment can improve the permeability of drugs to the skin and improve the efficacy. Some ointment based on silicone oil has good effect on scald, dermatitis, bedsore, etc.


07
Paint, ink and other industries
Can serve as the brightening agent of paint, add a few silicon oil to paint, can make paint does not float to wrap, do not crease, raise the brightness of paint film. Add a small amount of silicone oil to the ink, can improve the quality of printing, add a small amount of silicone oil to the polishing oil (such as car polish), can increase the brightness, protect the paint film, and have excellent waterproof effect.


08
New material industry
For other specific purposes, or with other materials to produce new materials




Matters needing attention


Contact with strong acid or alkali and lewis acid has the tendency of degradation and volatilization, the higher the temperature is, the more obvious the reaction is. A tendency to increase the viscosity of a strong acid or base in contact with it at low concentrations or at high temperatures for long periods of time until it is cross-linked.
