中国PBAT树脂市场预测及战略研究报告(2022版)

PBAT主要是以对苯二甲酸(PTA)[或对苯二甲酸二酯(DMT)]、已二酸(AA)、1,4-丁二醇(BDO)为原料,通过直接酯化或酯交换法而制得。PBAT广泛应用于包装(包括食品包装、化妆品盒、药品盒)、餐具、一次性医疗用品,农用薄膜等领域。
目前,国外PBAT主要生产企业包括意大利Novamont公司和德国巴斯夫。意大利Novamont公司是世界上最早进行生物降解塑料产业化的企业,Novamont的PBAT商品名是Origo-Bi,拥有PBAT产能10万吨/年。德国巴斯夫的PBAT商品名为ccoflex,产能为7.4万吨/年。另外德国巴斯夫巴斯夫一体化基地(广东)有限公司基地4.8万吨/年的PBAT改性料在建中。
2017年全球PBAT树脂需求量15.33万吨,同比增长8.0%;2018年全球PBAT树脂需求量16.62万吨,同比增长8.4%;2019年全球PBAT树脂需求量18.72万吨,同比增长12.6%;2020年全球PBAT树脂需求量23.11万吨,同比增长23.5%;2021年全球PBAT树脂需求量27.06万吨,同比增长17.1%。
2019年前国内PBAT发展较慢。随着2020年新“限塑令”的发布,行业发展明显提速。截止2021年底,国内PBAT总产能约55.0万吨/年,其中生产规模较大的有蓝山屯河(12.8万吨/年)、金发科技(12.0万吨/年)和长鸿高科(12.0万吨/年)。2020年PBAT产量激增至13万吨,2021年中国PBAT树脂产量17.50万吨,同比增长34.6%。
当前我国PBAT产业发展的快速发展,有效改善了PTA、BDO和AA产能过剩问题。与此同时,PBAT装置和PBT、PET装置具有很多类似之处,如聚合反应及真空系统、熔体输送及处理系统、热媒系统等,工程转化具有互通性。这些优势也为PBAT产业发展的灵活性带来巨大优势,可根据国内外原料及产品市场的变化和需求,实现了一套装置上多种产品的生产,提升产品的差别化率。
