The first phase of the Puixinjing Special Polyolefin Materials Project for New Energy applications, developed by Global Jilin Company, has been successfully put into operation. HQC Global Engineering, November 4, 2025. Recently, the first phase of this project was officially launched; Global Jilin Company played a key role in the technical research and development as well as in the engineering design for this project. The core unit of the first phase put into operation this time is a 140,000-ton/year ultra-high-purity molecular weight polyethylene plant. It utilizes the ultra-high-purity slurry process package jointly developed by Puyi Jingji and the company; the products manufactured by this plant possess excellent properties such as high purity, high molecular weight, and high consistency. Their performance metrics meet all requirements, and they even exceed those of similar international products. This breakthrough not only fills the gap in high-end polyolefin materials in China, but also represents a solid and crucial step forward on the path toward achieving self-sufficiency in key basic materials. It provides strong technical support for ensuring the security and stability of supply chains in strategic emerging industries such as new energy vehicles, lithium battery separators, semiconductor filtration materials, and high-end medical equipment. Since the commencement of construction for this project on June 28, 2024, it has faced numerous challenges such as novel manufacturing processes, tight deadlines, and complex and variable construction conditions. All the design staff have risen to these challenges by working together, relying on a spirit of efficient and pragmatic collaboration as well as their excellent professional skills, to ensure that the construction progress meets the owner’s requirements. Through continuous optimization of the design scheme and meticulous tuning of key equipment, the project was able to succeed in its first trial run with material feeding, enabling the production of qualified products throughout the entire line – which fully demonstrates the company’s strong capabilities in technology development and engineering design. The successful commissioning of the Phase 1 project for special polyolefin materials designed for Puyi Jingxin new energy applications has greatly boosted Huanqiu Jilin Company’s enthusiasm for independent innovation in new fields and technologies. This has enabled the company to make a full transition from a \"technology follower\" to a \"technology leader,\" fostering a development model in which production drives research and research promotes production. It accelerates the conversion of scientific and technological achievements and facilitates the implementation of more projects, thereby providing strong impetus for the company’s high-quality and sustainable development.
