Dimethicone fluid
Molecular formula: (CH3)3SiO[(CH3)2SiO]nSi(CH3)3

General-purpose 201 methyl silicone oil has good high and low temperature resistance, high flash point, low freezing point, low vapor pressure, good oxidation resistance and chemical stability, and can be used at high temperatures of -50℃~+20℃ It can be used for a long time within the range, isolated from air or in an inert gas, and can be used for a long time at 200 ° C, and has the advantages of small viscosity-temperature coefficient, small surface tension, high compressibility, good shear resistance, and good light transmittance. Excellent electrical insulation properties, arc resistance, corona resistance, good moisture resistance and good physiological inertia, so it has been widely used in various departments of industrial and agricultural production, national defense industry, scientific research and medical and health departments.

In addition to all the characteristics of 201 methyl silicone oil, 201R methyl silicone oil does not contain residual catalysts and their decomposition products due to the unique production process, and does not contain metal separation, so it is non-toxic, tasteless and odorless. Prominent, non-irritating to the human body, will not cause allergic reactions, and can be compatible with commonly used cosmetic components, these properties make silicone oil well used in the production of cosmetics to improve the performance of cosmetics.
The combination of low surface tension and viscosity of silicone oil makes it easy for other components of cosmetics to diffuse into a thin film on the skin without stickiness. Combination to obtain non-sticky products, volatile silicone oil can endow cosmetics with fast drying, smooth, anti-fouling luster and other properties. It is very important in eye beauty products and nail polish. In hair care products, silicone oil can add luster to the hair, and at the same time can play a role in styling and preventing the hair from sticking together. In shampoo, silicone oil can make the hair shine. Hair is easy to comb. In skin care products, the hydrophobic film formed by silicone oil can prevent other components from being washed away with water and keep the skin normally breathable. At present, silicone oil has become an important ingredient or auxiliary in many cosmetics. The outstanding characteristics of silicone oil are well-deserved as an important raw material for cosmetics, medical supplies and daily chemical products.

The product is a transparent colorless, odorless, odorless, non-toxic oily liquid. It has the characteristics of high flash point, low freezing point, good thermal stability and high and low temperature resistance. It can be used for a long time at -50-+180 ℃, such as isolated air or in inert gas for a long time, the temperature can reach 200 ℃. Silicone oil has low surface tension, high compressibility, good shear resistance, low viscosity-temperature coefficient, low dielectric loss; resistance to electric isolation, corona, non-flammability; hydrophobicity and moisture resistance, and also has good physiological inertia.

The main purpose: 
It is widely used in electrical insulation, lubrication, shockproof and moistureproof, defoaming, damping, heat carrier, hydraulic oil; it can be used as additives such as paint and glazing agent. It can also be used as an additive in plastic processing to improve the mold release and wear resistance of plastics; silicone oil is also an important component in formulating cosmetics and certain drugs.
