Ethylene Vinyl Acetate Copolymer
DuPont Packaging & Industrial Polymers
产品说明:
DuPont™ Elvax® 3128-1 is an extrudable ethylene-vinyl acetatecopolymer resin available in pellet form for use in conventionalextrusion e designed to process polyethylene resins.
Composition
9.3 % By Weight Vinyl Acetate comonomer content
Thermal Stabilizer: BHT antioxidant
Applications
This resin is designed to provide a low temperature heat seal toitself or many other materials commonly used in flexible packagingapplications. The melt properties of this resin allow it to beprocessed on blown film e over a wide range of filmthickness and blow-up ratios. It can also be co-extruded with avariety of other polymers. This resin is typically used as lowtemperature seal layer in co-extruded films.
