Product Name:Polymethylhydrosiloxane
English Name:Polymethylhydrosiloxane
CAS No.:9004-73-3
Aliases:Polymethylpolysiloxane, Hydrogen-containing silicone oil, Methyl hydrogen silicone oil, PMHS
Molecular Formula:[(CH3)HSiO]n
Physical Properties:Colorless or light yellow transparent oily liquid, odorless, insoluble in water, soluble in organic solvents such as benzene, toluene, and gasoline. Contains active Si-H bonds that can react with hydroxyl and alkenyl groups. Has excellent hydrophobicity and heat resistance stability, with a relative density of approximately 0.98-1.10 and a refractive index of 1.39-1.41.
Uses:Used as a waterproofing agent for fabrics, an anti-fogging agent for glass, a release agent, and a defoaming agent. It can be used for preparing modified silicone oils and silicone rubbers, and also serves as a hydrophobic treatment agent for rubber and plastics.
