What are the prospects for PBS industrialization?

Thread Content

　　Polybutylene succinate (PBS) entered the field of materials research in the 1990s and quickly became one of the hot research materials for general-purpose biodegradable plastics that can be widely promoted and applied. Compared with degradable plastics such as PCL, PHB, and PHA, PBS is extremely cheap, with a cost of only 1/3 or even lower than the former. It has good heat resistance, and the heat deformation temperature and product use temperature can exceed 100°C. 　　It is reported: 　　Yangzhou Hanjiang Grace Polymer Materials Co., Ltd. and Engineering Plastics Institute of Physics and Chemistry Technology, Chinese Academy of Sciences * * The Engineering Research Center cooperated to establish Yangzhou Hanjiang Jiamei Polymer Materials Co., Ltd. and built a 20,000 tons/year PBS production line. 　　Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd. follows the principle of "one planning, phased implementation" to build an industrialization project with an annual output of 20,000 tons of fully biodegradable new materials (PBS). The first phase of 3,000 tons/year PBS has been completed. 　　Anqing Hexing Chemical Co., Ltd. cooperated with Tsinghua University to build a 5,000 tons/year PBS production line. What are the prospects for the industrialization of PBS?
