Product Name:EVA 250
English Name:Ethylene-Vinyl Acetate Copolymer
CAS No.:24937-78-8
Aliases:Ethylene-Vinyl Acetate Copolymer, EVA Resin, Poly(ethylene-co-vinyl acetate)
Molecular Formula:(C2H4)x(C4H6O2)y
Physical Properties:Translucent pellets; density 0.951 g/cm³; melt flow rate 25 g/10 min; VA content 28%; tensile strength 11 MPa; elongation at break about 750%; tensile modulus 19 MPa; Shore hardness 75A; melting point 70°C; Vicat softening point 42°C; ring-and-ball softening point 127°C; cloud point 66°C; insoluble in water, and swellable/soluble in aromatic organic solvents when heated.
Uses:Used as the base resin for food-grade hot melt adhesives, suitable for packaging sealing, carton edge sealing, book binding, and other bonding applications requiring low odor and food-contact safety. The high VA content and moderate melt flow rate provide good flexibility, wetting, and processing flow, and it can be formulated with waxes, tackifying resins, and other additives.
Technical Specifications:
VA content is 28% and melt flow rate is 25 g/10 min (190°C/2.16 kg).
Density is 0.951 g/cm³ and melting point is 70°C, suitable for low-temperature hot-melt processing.
Tensile strength is 11 MPa and elongation at break is about 750%, providing good flexibility.
Shore hardness is 75A and tensile modulus is 19 MPa.
Ring-and-ball softening point is 127°C, Vicat softening point is 42°C, and cloud point is 66°C.
