Dimethylcyclosiloxane (DMC)
Date:2020-05-02 11:49:38 | Visits:

The main raw material of dimethylcyclosiloxane DMC is dimethyldichlorosilane, synthesized by hydrolysis, with silicon-oxygen (Si-O) bond as the main chain, and the organic atom directly connected to the organic group on the silicon atom Compound. It is the main intermediate of organic silicon. It is mainly used for ring-opening polymerization with silicone oil, silicone rubber, and silicone resins with different degrees of polymerization. Products that are further processed into polymer products are widely used in various fields such as construction, electronics, textiles, automobiles, personal care products, food and mechanical processing, and also have a small number of direct applications.

Properties and Uses

 It is colorless, inflammable, and can not dissolve in water, but dissolve in organic solvents such as benzene, etc. 

Dimethylcyclosiloxane (DMC) is the main raw material of producing silicone rubber and silicone oil. It is also wildly used in handling silicone rubber packing and cosmetics. The silicone rubber, silicone oil and other polysiloxane products which are made from DMC can be further processed into various modified silicone rubber and silicone oil with very good high and low temperature resistance, aging resistance and insulating property.
