Dimethylcyclosiloxane,DMC

Chemical name

DMC: (Dimethylcyclosiloxane)

Content: D3、D4、D5、D6、D7

 

Formula

[(CH3)2SiO]n   n=3,4,5,6,7

 

Physical and Chemical nature

Physical nature:

Dimethylcyclosiloxane(DMC)is colorless and transparent oily liquid. Flammable.

Density range is 0.95~0.97g/cm3, the datas of the cyclosiloxane with different number of Si--O links as follows:

Chemical nature:

Low Molecular Weight of cyclic siloxane would break the links, then forms the high linear polymer under the catalyst of acid or alkaline. In the process of polymer, polysiloxane of different molecular weights can be produced by controlling the ending agent and the relative concentration of cyclic.

 

Property＆Application

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.
