Product Name:Ethylene-Vinyl Acetate Copolymer (EVA)
English Name:Ethylene-Vinyl Acetate Copolymer (EVA)
CAS No.:24937-78-8
Aliases:EVA, Ethylene-acetic acid vinyl ester copolymer, Ethylene vinyl acetate
Molecular Formula:(C2H4)x(C4H6O2)y
Physical Properties:White or slightly yellow translucent pellets with a density of 0.92-0.95 g/cm³ and a melting point of 65-95°C. It exhibits excellent flexibility, low-temperature resistance (usable at -70°C), resistance to stress cracking and weathering. It has good chemical stability, is insoluble in water, and soluble in aromatic hydrocarbons and chlorinated hydrocarbons and other organic solvents.
Uses:Widely used in the packaging industry as sealing and leakage-proof materials; in automotive manufacturing for firm connection of components; in electronic products as insulation, protection and cushioning materials; and in the construction field as sound insulation and thermal insulation materials. It is also used in foamed shoe materials, hot melt adhesives and photovoltaic encapsulant films.
Technical Specifications:
Density: 0.92-0.95 g/cm³
Melting point: 65-95°C
Elongation at break: ≥300%
Vinyl acetate (VA) content: 5%-40% (depending on grade)
Packaging: 25 kg/bag
