 一.简介Brief introduction

辐射交联聚乙烯泡沫(XPE)材料(卷材)是以低密度聚乙烯(LDPE)与乙烯—醋酸乙烯共聚物(EVA)为主要原料,添加发泡剂AC等多种化工原料,经混合、加工、成形,再经发泡、定型、后处理等系列加工工艺生产出来的一种具有较好的物理机械性能、手感舒适、热加工性好的闭孔型泡沫材料。该泡沫材料具有环保无毒,泡孔较细密均匀、强韧、隔热、隔音效果好、耐腐蚀性高、无毒、回弹性较好、吸水性小、手感舒适等多种优异性能。

 is low density polyethylene (LDPE) and ethylene - vinyl acetate copolymer (EVA) as the main raw materials, adding foaming agent AC and other chemical raw materials, after mixing, processing, forming, A closed cell foam material with good physical and mechanical properties, comfortable hand feel and good thermal workability is produced by a series of processing technologies such as foaming, shaping and post-treatment. The foam material has environmental protection and non-toxic, fine and uniform bubble hole, strong, good heat insulation, sound insulation effect, high corrosion resistance, non-toxic, good resilience, small water absorption, comfortable feel and other excellent properties.
