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。
EVA树脂的特点是具有良好的柔软性,橡胶般的弹性,在-50℃下仍能够具有较好的可挠性,透明性和表面光泽性好,化学稳定性良好,抗老化和耐臭氧强度好,无毒性。与填料的掺混性好,着色和成型加工性好。
EVA树脂用途很广。一般情况下,乙酸乙烯含量在5%以下的EVA,其主要产品是薄膜、电线电缆、LDPE改性剂、胶粘剂等;乙酸乙烯含量在5%~10% 的EVA产品为弹性薄膜等;乙酸乙烯含量在20~28%的EVA,主要用于热熔粘合剂和涂层制品;乙酸乙烯含量在5%~45%,主要产品为薄膜(包括农用薄膜)和片材,注塑、模塑制品,发泡制品,热熔粘合剂等。
乙烯-醋酸乙烯共聚物的的成型加工:
EVA可注塑、挤塑、吹塑、压延、滚塑真空热成型、发泡、涂覆、热封,焊接等成型加工。
