What is dimethyl silicone oil? What are the main uses of dimethyl silicone oil?
brief introduction
Dimethyl silicone oil is also known as methyl silicone oil and polydimethylsiloxane liquid. It is a odorless, odorless, non-toxic colorless transparent viscous liquid. Soluble in benzene, toluene, xylene, ether, partly soluble in ethanol, butanol, acetone, insoluble in cyclohexanol, methanol, paraffin oil, vegetable oil. It has excellent water repellency, moisture resistance, good light transmittance and chemical stability.
Application of dimethyl silicone oil
Dimethyl silicone oil is widely used as insulating, heat-resistant, moisture-proof filler, high-efficiency defoamer, demoulding agent, lubricant and surface treatment agent. The industries involved include daily chemical industry, rubber, plastics, latex and other industries, machinery, automotive, electronic and electrical industries, clothing industry, leather industry, pharmaceutical industry, food industry and some new materials industry.
01 Daily Chemical Industry
Used in skin cream, bath, shampoo and other cosmetic formulations, with excellent softening effect and silky feel, improve the moisturizing and protection of the skin and so on.
02 Plastic Industry
Because dimethyl silicone oil is not sticky to rubber, plastics, metals and so on, it is used as release agent, isolator and brightener in the production of some rubber, plastics, latex, polyurethane products and crafts, so as to make the surface of products clean, smooth and clear.
03 Machinery, automobile, electrical appliances and other industries
Machinery, automobile, instrumentation, electronic and electrical industries, used as high-grade lubricants, liquid springs, cutting fluid, buffer oil, transformer oil, high and low temperature brake oil, brake oil, instrument shock absorber oil, frame modelling release agent, etc. It can also be used as a liquid spring and in the landing device of an aircraft.
04 Textile and Clothing Industry
It can be used as softener, hydrophobic agent, feel improver, lubrication of sewing thread, lubrication of chemical fibre spinneret, clothing liner additive, defoamer, etc.
05 Leather and Leather Chemical Industry
Leather and leather chemical industry will add this product to other additives, can be used as softener, hydrophobic agent, hand feeling agent, defoamer, brightener and so on.
06 Medicine and Food
Pharmaceutical and food industries are used as defoamers and lubricants.
Dimethyl silicone oil has no toxicity to human body and is not decomposed by body fluids, so it is also widely used in medical and health undertakings. With its defoaming effect, oral gastrointestinal defoaming tablets and pulmonary edema defoaming aerosol were prepared. Adding silicone oil to the ointment can improve the penetration ability of the drug to the skin and its efficacy. Some ointments based on silicone oil have good effects on scalds, dermatitis and bedsores.
07 Paint, Ink and Other Industries
It can be used as a brightener of paint, adding a small amount of silicone oil to the paint, so that the paint can not float, wrinkle, and improve the brightness of the paint film. Adding a small amount of silicone oil to ink can improve printing quality. Adding a small amount of silicone oil to polishing oil (such as automobile polishing oil) can increase brightness, protect paint film, and have excellent waterproof effect.
08 New Material Industry
Used for other specific purposes or copolymerization with other materials to produce new materials
Matters needing attention
Contact with high concentration of strong acid or alkali substances and Lewis acid tends to degrade and volatilize, and the higher the temperature, the more obvious the reaction is. Low concentration of strong acid or alkali contact with it or at high temperature for a long time has a tendency to increase the viscosity until cross-linking.
