The production line was jointly invested by the above-mentioned two units with an investment of 50 million yuan. The two units jointly established Yangzhou Gurse Gray Polymer Materials Co., Ltd. for this joint venture. According to Dr. Ji Junhui, chief engineer of the National Engineering Research Center for Engineering Plastics of the Institute of Physics and Chemistry, Chinese Academy of Sciences, after the trial run, the 20,000-ton/year PBS production line has been able to fully realize industrialized production and is expected to become the world's largest commercially available PBS plant.
PBS is a new type of biodegradable bioplastic. It has unique advantages in degradable plastics with excellent thermal performance, processing performance and cost performance. The heat distortion temperature is close to 100°C, and after modification it can exceed 100°C, and it can fully meet the heat resistance requirements of daily products, and therefore it can be used in all living things. Among the degradable plastic products, the market prospects are the most promising in the industry.
Prior to the commissioning of the Yangzhou project, only two or three companies in the world were able to produce PBS industrially. The total annual production was less than 50,000 tons. According to conservative estimates, there is currently only 500,000 tons/year of demand in the Chinese market, which can be described as unlimited business opportunities.
At present, the National Engineering Research Center for Engineering Plastics of the Institute of Physics and Chemistry of the Chinese Academy of Sciences possesses a complete set of PBS production technology including core production equipment. With independent intellectual property rights, the developed PBS has a relative molecular mass of 200,000, and the mechanical properties are close to those of PE and PP. General plastics use requirements, and the processing performance is very good, can be all kinds of molding processing in general processing equipment.
The PBS industrialization project was included in the Innovation Project of the Chinese Academy of Sciences in 2002, and it has received national attention. In 2005, it was listed as one of the key research topics for environmentally friendly materials. PBS has become a national-level biodegradable plastic focused on industrialization and won. Industrialization opportunities, but also become the leader in the industrialization of domestic biodegradable plastics. The successful test of the 20,000-ton/year PBS production line indicates that China's PBS biodegradable plastics industry has reached the international advanced level.
The reporter learned from the National Engineering Research Center for Engineering Plastics of the Institute of Physics and Chemistry of the Chinese Academy of Sciences on the 26th that the 20,000-ton/year PBS production line jointly established by the center and Yangzhou Jiajiang Jiamei Polymer Materials Co., Ltd. has been successfully tested.
