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.
Package, Storage and
Handling:
Packed
in 200L iron drum or plastic drum (N.W.190kg) or packed in International
Bulk Container, net weight 950kg/IBC or ISO TANK. Store in a cool, dry,
well-ventilated area and keep away from oxidant, acid and alkali.
Stored
in a shady, cool and ventilated storehouse. It should be kept away from
kindling and heat sources. Avoid direct sunlight.
Transportation:
When transported, avoid rain and direct sunshine. Transported as danger
commodity.
