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。
