Product Details

Introduction:

Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane.

The physical properties of hexamethyldisiloxane

colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents.

Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, and medical electronic components. The Si O-Si bond in the molecular chain structure of hexamethyldisiloxane has a high chemical bond energy (460 5 kJ/mol), the polysiloxane prepared from it as a sealing agent has good thermal and chemical stability.
