Product Name:Poly(vinyl acetate)
English Name:Poly(vinyl acetate)
CAS No.:9003-20-7
Aliases:PVAc, Poly(ethenyl acetate), Acetic acid ethenyl ester homopolymer
Molecular Formula:(C4H6O2)x
Physical Properties:White or slightly yellow transparent granules or powder, odorless, with a density of approximately 1.19 g/cm³ and a softening point of about 38°C. Insoluble in water, soluble in esters, ketones, aromatic hydrocarbons and other organic solvents. Thermoplastic, stable to light and heat, but partially degrades under prolonged high temperature.
Uses:Mainly used for producing adhesives, coatings, textile finishing agents and paper strengthening agents. Also used as raw materials for architectural emulsions, wood adhesives and poly(vinyl acetate) latex paints, widely applied in packaging material bonding and fiber processing fields.
Technical Specifications:
Molecular weight: determined by degree of polymerization, typically 10,000–100,000
Softening point: approximately 38°C
Density: approximately 1.19 g/cm³
Glass transition temperature: approximately 28°C
Appearance: transparent or slightly yellow solid granules
