Product Name:Methyl-Vinyl (Siloxane and Polysiloxane)
English Name:Methyl-Vinyl (Siloxane and Polysiloxane)
CAS No.:68037-87-6
Aliases:Vinyl-terminated Polydimethylsiloxane, Vinyl Silicone Oil, Crosslinking Agent C-14A
Molecular Formula:CH2=CH[Si(CH3)2O]nSi(CH3)2CH=CH2
Physical Properties:Colorless to light yellow transparent liquid, free from mechanical impurities; viscosity varies with molecular weight, typically from low to high viscosity fluid; relative density about 0.97–1.02 g/cm³; insoluble in water, soluble in toluene, xylene, gasoline and other organic solvents; excellent high and low temperature resistance, weather resistance, chemical stability and electrical insulation.
Uses:Mainly used as a crosslinking agent for addition-curing silicone rubber. It is used together with hydrogen-containing silicone oil to form a three-dimensional network structure through platinum-catalyzed addition reaction. Widely used in vulcanization and molding of silicone products, such as silicone seals, silicone tubes, electronic potting adhesives and medical-grade silicone.
Technical Specifications:
Appearance: colorless transparent liquid, no mechanical impurities.
Viscosity (25℃): 100–10000 mPa·s, customizable.
Vinyl content: 0.1%–5.0%, customizable.
Volatile content (150℃/3h): ≤2.0%.
Flash point: ≥100℃.
