According to the results of the 2025 Science and Technology Awards announced by the Chinese Chemical Society, the project \"Development of Metallocene Polyethylene Technology Suite and Its Industrial Application\", submitted by Lanzhou Petrochemical, won the first prize in the Science and Technology Progress Award category. This technology was developed through collaboration between Zibo Xinsu Chemical Co., Ltd. and Lanzhou Petrochemical; it reflects the commitment of both parties to the pursuit and development of new technologies and products, as well as their firm determination to change the situation in which metallocene catalysts rely on external technologies and are subject to others’ control. The catalyst is the core of polyethylene, and its quality determines the quality of the polymer. For decades, it has been monopolized by foreign companies, resulting in high prices and limited availability. Xinsu Chemical has been committed to developing metallocene catalysts through independent research and development. After more than a decade of relentless efforts, it has achieved success; these catalysts are now in use on an industrial scale at companies such as Qilu Petrochemical, Yangzi Petrochemical, Zhongyuan Ethylene, Lanzhou Petrochemical, Dushanzi Petrochemical, as well as in Russia. They enable long-term operation in both dry and condensed states for gas-phase polymerization processes like Unipol and BP. The low-density film materials produced, namely mPE1018 and mPE1012, exhibit excellent properties in terms of dart impact strength and haze. The PE-RT pipe material mPE3010 surpasses the quality of imported products. As a pioneer in this field, Lanzhou Petrochemical combined metallocene catalysts for polymerization with relevant production processes. Building on its existing technologies for producing 60,000 tons per year of metallocene polyethylene via the vapor phase method, as well as the results achieved from operations at a capacity of 300,000 tons per year, it developed a technology for producing 450,000 tons per year of polyethylene via the same method. Over the past three years, the output of metallocene polyethylene has reached nearly 400,000 tons, demonstrating significant achievements in terms of innovation and efficiency. The successful development and application of the metallocene polyethylene technology set have broken through the bottlenecks in China’s industrial development, creating a fully self-sufficient high-end industrial chain that includes \"metallocene catalysts, polymerization processes, and polyethylene products\", thereby contributing to the high-quality development of China’s large-scale petrochemical enterprises!
