Recently, Sinopec Yangzi Petrochemical has successfully independently developed ultra-high molecular weight polyethylene (UHMWPE) with a molecular weight exceeding 10 million, with overall product performance indicators reaching advanced international standards.
UHMWPE is a high-performance thermoplastic engineering plastic with excellent comprehensive properties, widely applied in high-end manufacturing fields including aerospace, marine engineering, new energy equipment, biomedicine, and national defense industry. In particular, UHMWPE with a molecular weight of 10 million boasts prominent advantages in wear resistance, impact resistance, chemical corrosion resistance, self-lubrication and lightweight performance. In addition, the material features recyclability and circular utilization value. For a long time, the core manufacturing technology of high-end 10-million-level UHMWPE has been monopolized by foreign enterprises.
To break the technical barrier, Yangzi Petrochemical focused on independent catalyst systems and exclusive polyolefin new processes, overcoming a series of core technical bottlenecks including the scaled batch preparation of innovative catalysts. Through multiple rounds of experimental optimization, parameter debugging and operating condition verification, the team steadily achieved stable production of UHMWPE with a molecular weight exceeding 10 million.
During the technical research and development process, the project team formulated detailed experimental operation plans and product testing standards. The team strictly controlled key nodes of the entire production process, precisely monitored operational parameters and product quality specifications, and realized one-time successful product development with zero trial errors.
Moving forward, Yangzi Petrochemical will continue to optimize technical parameters and continuous production workflows, develop a diversified portfolio of high-end polyethylene products, and accelerate the industrialization of high-value new chemical materials to further strengthen its competitiveness in the global high-performance new materials market.
