Appeel® 2044
乙烯醋酸乙烯共聚物
DuPont Packaging & Industrial Polymers
产品说明:
DuPont™ Appeel® 2044 is a blown or cast film resin designed to be a sealing layer for lidding applications. It provides a peelable seal over a broad temperature range to a number of container materials including ABS, CPET, HDPE, PETG, PP, PS, and APET. It will provide stronger seals to HIPS, PVC, and HDPE. Appeel® 2044 is a modified ethylene vinyl acetate polymer available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene resins.

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。
