Elvax® 3200-2
乙烯醋酸乙烯共聚物
DuPont Packaging & Industrial Polymers
产品说明:
DuPont™ Elvax® 3200-2 is an extrudable, wax modified, ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.
Composition
22.5 % By Weight Vinyl Acetate comonomer content
Wax
Thermal Stabilizer: BHT antioxidant
Applications
This resin is designed to provide a low temperature heat seal to itself or many other materials commonly used in flexible packaging applications. The melt properties of this resin allow it to be processed on extrusion coating equipment over a wide range of line speeds and coating thicknesses. It can also be coextrusion coated with a variety of other polymers. This resin is typically used as a lidding sealant for a variety of formed containers, in replacement of solvent applied heat seal lacquers. It will provide a good seal against HDPE film and sheet, polypropylene film, PVDC, rigid vinyl, rigid and foamed polystyrene, and nitrocellulose coatings.
Elvax®3200-2 will provide a low-temperature heat seal. The actual heat seal initiation temperature, sealing range, and ultimate seal strength will depend on variables such as coating structure, thickness, substrate type, thermal conductivity of structure, type of heat sealing equipment, end-use environment, and many others.
Because a quantitative description of heat seal performance can only be determined for a given application, it is imperative that heat seal properties be evaluated for each specific application. However, for a relative comparison of heat seal initiation temperatures, the Vicat temperature of each Elvax® resin can be considered.

乙烯-醋酸乙烯共聚物简称EVA，一般醋酸乙烯（VA）含量在5%～40%。与聚乙烯相比，EVA[1]由于在分子链中引入了醋酸乙烯单体，从而降低了高结晶度，提高了柔韧性、抗冲击性、填料相溶性和热密封性能，被广泛应用于发泡鞋料、功能性棚膜、包装膜、热熔胶、电线电缆及玩具等领域。
