PROPERTIES AND APPLICAITONS:
|
|
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.
