In 2026, the 25th National \"Safety Production Month\" will be observed – with everyone emphasizing safety and knowing how to respond to emergencies, as well as working to identify and address potential risks and hazards. On June 25th, the Zhejiang Ecology and Environment Bureau issued its approval regarding the environmental impact assessment report for Zhejiang Zhiying New Materials Co., Ltd.’s project to produce POE metallocene catalysts on a tonnage scale per year, as well as special polyesters through pilot-scale production. According to the report, the company plans to invest 34.4 million yuan to rent Workshop No. 9 at the Daishan New Materials Research and Experiment Base of the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, with a total construction area of 1,147.34 square meters. It will purchase equipment such as depolymerization reactors, reaction reactors, distillation towers, and centrifuges, in order to build one pilot-scale production unit for POE metallocene catalysts and one pilot-scale production unit for special polyesters. The maximum designed capacity of these pilot units is respectively on the tonnage and kilotonnage scale; the actual pilot production scales are 0.3 tons per year for the POE metallocene catalyst pilot unit and 200 tons per year for the special polyester pilot unit. On June 25, 2025, the kickoff meeting for the engineering design of the 400,000-ton/year POE plant for Zhejiang Petrochemical Co., Ltd.’s high-end new materials project was successfully held in Hangzhou. The process package was provided by Zhejiang Zhiying Petrochemical Technology Co., Ltd., a subsidiary of Zhejiang Ruizhi Holding Group Co., Ltd., while Shanghai Zhiying Chemical Technology Co., Ltd. was responsible for the engineering design. This facility utilizes the POE process technology with independent intellectual property rights, developed by Zhejiang Zhiying United Universities. It has overcome numerous critical technical challenges; through the use of highly efficient Vemetsol™ metallocene catalysts, Zyneson™ co-catalyst technologies, as well as efficient reactors and devolatilization systems, a unique ZoneFlex™ solution polymerization process has been created. Building on earlier pilot tests and scale-up trials at 1,000 tons, a complete process technology capable of handling 100,000 tons per production line has been successfully developed.
