DIMETHICONE OIL

Dimethicone Oil usually refers to linear polysiloxane products that maintain liquid state at room temperature. 
Dimethicone Oil is generally divided into methyl silicone oil and modified silicone oil. 
The most commonly used Dimethicone Oil - methyl silicone oil, also known as ordinary silicone oil, whose organic groups are all methyl, has good chemical stability, insulation and hydrophobic properties. 

CAS Number : 9006-65-9
EC  Number : 618-433-4
Molecular Formula :  6H14OSi
Average mass      :  130.260 Da

Dimethicone Oil is prepared by hydrolysis of dimethyl dichlorosilane with water to obtain the initial polycondensation ring. 
The ring is cracked and rectified to obtain the low ring. 
Then the ring, sealing agent and catalyst are put together to obtain a mixture of different polymerization degrees. 
Dimethicone Oil can be prepared by vacuum distillation to remove the low boiling matter.

Appearance and viscosity of Dimethicone Oil
Dimethicone Oil is generally colorless (or light yellow), odorless, non-toxic and non-volatile liquid. 
Dimethicone Oil is insoluble in water, methanol, ethylene glycol and 2-ethoxyethanol. 
Dimethicone Oil can be miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, and slightly soluble in acetone, dioxane, ethanol and butanol. 

Dimethicone Oil has low vapor pressure, high flash point and ignition point, and low freezing point. 
With the different number of chain segments n, the molecular weight increases and the viscosity also increases. 
Dimethicone Oil can have different viscosities, from 0.65 centistokes to millions of centistokes. 
If low viscosity Dimethicone Oil is to be prepared, acidic clay can be used as catalyst, and the polymerization can be carried out at 180 ℃, or sulfuric acid can be used as catalyst, and the polymerization can be carried out at low temperature. 
Alkaline catalyst can be used to produce high viscosity Dimethicone Oil or viscous substances.

Features of Dimethicone Oil
