en.Wedoany.com Reported - Recently, Sinopec Yangzi Petrochemical successfully developed ultra-high molecular weight polyethylene (UHMWPE) with a relative molecular weight of over 10 million, achieving product performance indicators at an internationally advanced level.
Ultra-high molecular weight polyethylene is a thermoplastic engineering plastic with excellent comprehensive properties, widely used in high-end manufacturing fields such as aerospace, marine engineering, new energy equipment, biomedical, and national defense. Among them, the 10 million molecular weight grade product offers significant advantages in wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, and lightweight, and can be recycled. However, its core technology has long been monopolized by foreign countries. Based on this, Yangzi Petrochemical focused on its own catalyst system and proprietary new polyolefin process, successfully overcoming multiple key technical challenges, including the large-scale batch preparation of new catalysts. After multiple rounds of experimental optimization, parameter tuning, and working condition verification, the product's relative molecular weight was finally and stably broken through 10 million. During the project's critical phase, the research team developed detailed experimental operation and product testing plans, strictly controlled key nodes of the production process, and rigorously monitored process operation parameters and product quality standards, ultimately achieving a successful one-time product development.
In the future, the company will continue to optimize technical parameters and continuous production processes, develop more types of high-end polyethylene series products, and advance the industrialization process of high-value-added new materials.
