生物可降解塑料发展现状及展望

Development status and prospect of biodegradable plastics

随着各类“限塑”政策的落地,可降解塑料行业近年进入快速发展轨道,生产技术逐步成熟,产能处于高速增长期。简述了各类可降解塑料的种类、原料、性能,对常见的可降解塑料聚乳酸(PLA)、对苯二甲酸-己二酸丁二醇酯(PBAT)、聚丁二酸丁二醇酯(PBS)、聚乙醇酸(PGA)的生产工艺及产业发展现状进行了总结分析,结合市场行业现状,对常见可降解塑料的发展趋势进行了展望。

With the implementation of various plastics restriction policies in recent years,the biodegradable plastics industry has developed rapidly,the production technology has gradually matured,and the production capacity is in a period of rapid growth.The types,raw materials and properties of various degradable plastics are briefly described.The production processes and industrial development status of common degradable plastics such as polylactic acid(PLA),polybutylene adipate-terephthalate(PBAT),polybutylene succinate(PBS)and polyglycolic acid(PGA)are summarized and analyzed.Combined with current situation,the development trend of common degradable plastics is prospected.
