Performance and Application

It is colorless, inflammable, and cannot dissolve in water, but dissolve in organic solvents such as benzene, etc. Viscosity is about 2.1 ~ 2.5 mm 2/s, freezing temperature 0 ℃ ~ 5 ℃. It can be used to synthesize silicone polymer by acid or alkali catalysis to manufacture silicone oil, silicone rubber, etc.


Application Industry

Here lists some applications of Dimethylcyclosiloxane (DMC), if you want to know more about applications of silicone liquid, you could find more applications in here.

1. Silicone: raw materials for raw rubber, OH polymer, silicone oil and other silicone products;

2. Textile industry: used as textile auxiliaries.


Packaging and Storage

Packed in plastic / iron drums, net weight 200kg/drum, or International Bulk Container, net weight 1000kg/IBC. Store in a cool, dry, well-ventilated area and keep away from oxidant, acid and alkali. The storage area should be equipped with the corresponding species and quantity of fire equipment and leakage emergency equipment. Handling according to hazardous substances. Be careful when loading and unloading to avoid damages of the package.
