内容概要:乙烯-乙烯醇共聚物(EVOH)、聚偏二氯乙烯(PVDC)和聚酰胺(PA)是全球公认的三大 高阻隔材料。20世纪50年代,美国杜邦公司通过乙烯与醋酸乙烯共聚、醇解制得EVOH。1972年,日本 可乐丽公司将EVOH成功地实现了工业化。由于乙烯醇单体不能稳定存在,因此目前合成EVOH共聚物 的生产工艺涉及聚合和醇解两步:首先,在4-5 MPa压力下,以甲醇或叔丁醇作溶剂,乙烯与醋酸乙烯 通过自由基聚合得到EVA共聚物,接着以甲醇为溶剂,强碱氢氧化钠为催化剂,通过对EVA共聚物醇解 得到EVOH共聚物。这个过程中还会产生副产品醋酸甲酯,这是目前全球工业化生产EVOH的主要方 法。EVOH已成为未来新材料领域重要发展方向,全球EVOH企业也在积极扩能改造。数据显示,截至 2024年底,全世界共有4家公司生产EVOH,总产能约为21.45万吨/年,装置开工率高,产品供不应求。 全球EVOH供给集中在美国、中国、比利时、英国五地,其中美国产能达9.9万吨,占全球总产能的 46.2%;其次为中国(包括中国台湾),产能为4.25万吨,占比19.8%。比利时以16.3%的占比位居第 三。近年来,随着高阻隔、刚性塑料包 ...
