Dimethylsiloxane Cyclic Mixture Description

Dimethylsiloxane cyclic mixture abbreviated as DMC silicone intermediate is a colorless transparent or milky white cyclic oily liquid.

DMC is a flammable, odorless, insoluble in water, soluble in benzene and other organic solvents. It can be polymerized into silicone polymers under acid and alkali catalysis, and is used for the production of silicone oil, silicone rubber, etc. It can also be used as a methylation reagent. Compared with other methylation reagents such as iodomethane and dimethyl sulfate, dimethyl carbonate is less toxic and biodegradable.

Dimethylsiloxane Cyclic Mixture: Guide

Dimethylsiloxane cyclic mixture is the primary form, Dimethylsiloxane is an organic-inorganic compound synthesized by hydrolysis of dimethyl dichlorosilane as the main raw material, with silicone-oxygen (Si-O) bond as the main chain, and organic groups directly attached to the silicon atom.

Primary forms of dimethyl cyclic siloxane molecular structure shows ring, mainly including hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), dodecamethylcyclohexasiloxane (D6), the content of more than 50% of the colorless transparent or milky white liquid, flammable, no odor, insoluble in water, soluble in benzene and other organic solvents.
