In the domestic research and industrialization of PBS, the National Engineering Research Center for Engineering Plastics of the Institute of Physics and Chemistry of the Chinese Academy of Sciences and Tsinghua University are at the forefront.
In 2006, Anhui Anqing Hexing Chemical Co., Ltd. built an extrusion and injection-grade PBS production line with an annual output of 3,000 tons based on the technology of Tsinghua University. In 2009, the 10,000-ton extrusion and injection-grade production line has also been successfully put into operation.
At the end of 2006, the Institute of Physics and Chemistry of the Chinese Academy of Sciences and Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd. reached a cooperation agreement, authorizing Xinfu Pharmaceutical to produce 20,000 tons/year of PBS. The annual output of injection molding grade, extrusion grade and blown film grade PBS will be 3000 tons in the first phase and 20000 tons in the second phase. This production line uses the one-step polymerization process of the Institute of Physics and Chemistry, and is the world's first one-step PBS production device.
In 2006, the Institute of Physics and Chemistry of the Chinese Academy of Sciences signed a PBS project cooperation contract with Jiangsu Hanjiang Jiamei Polymer Materials Factory, with an investment of 50 million yuan and an output of 13,000 to 20,000 tons per year. And it was successfully tested in 2007.
Shandong Huiying New Material Technology Co., Ltd. also used the technology of the Chinese Academy of Sciences to build a set of 20000 tons/year PBS device, and put it into production in 2013. Coupled with the 500-ton/year plant built in 2012, the total production capacity reaches 25,000 tons, which is known as the world's largest PBS production base. Recently, its products have also been exported to Spain, which has brought opportunities for my country's PBS products to open up new international markets.
In 2013, the technology of the Institute of Physics and Chemistry of the Chinese Academy of Sciences settled in Shanxi Jinhui Zhaolong High-tech Co., Ltd., with a production capacity of 20,000 tons/year.
In 2009, Kingfa Technology launched the PBSA project in Zhuhai, completed trial production in May 2010, and started production in 2011. The first-phase production capacity is 30,000 tons/year, and the second-phase production capacity is 90,000 tons/year. Its PBSA products are mainly used for export.
In 2012, the Lanshan Tunhe plant with an annual output of 10,000 tons of PBS was successfully commissioned, marking the birth of PBS degradable plastics that fill the gaps in the five northwestern provinces of my country in Xinjiang, and it has also become one of the five domestic PBS degradable plastic manufacturers. Shanghai Juyou Chemical is responsible for the supply of patented equipment and engineering design for this project.
