Methylsilicone oil is colorless, odorless, and not easily volatile; Insoluble in water, methanol, and ethylene glycol, it can be miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride, or kerosene, and has a low vapor pressure, high flash and ignition points. Methylsilicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness, and small surface tension. It also has a low viscosity temperature coefficient and high compression resistance.
The primary form of dimethyl cyclic siloxane is an organic-inorganic compound synthesized by hydrolysis of dimethyl dichlorosilane as the main raw material, with silicon oxygen (Si-O) bonds as the main chain and organic groups directly connected to silicon atoms. The primary form of dimethyl cyclosiloxane exhibits a cyclic molecular structure, mainly including hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), dodecylcyclohexasiloxane (D6), as well as hexamethylcyclotrisiloxane (D3) and/or octamethylcyclotetrasiloxane (D4) and/or decamethylcyclopentasiloxane (D5) and/or dodecylcyclohexasiloxane (D6) with a content of over 50%. It is a colorless, transparent or milky white liquid that is flammable, odorless, insoluble in water, and soluble in organic solvents such as benzene.
