The total investment in the Yongzhou Land Port Hub amounts to 4 billion yuan, and an agreement was recently signed for a project related to polyimide PI films. Recently, Yongzhou Land Port Hub Investment and Development Group Co., Ltd., together with companies such as Beijing Ruihexinye Investment Co., Ltd. and Henan Chenlong Chemical Co., Ltd., held a ceremony to sign various projects. Among these, the most notable is the project for producing 5,000 tons of high-end polyimide (PI) films per year. This key project, with a total investment of 4 billion yuan, will provide strong impetus for the development of the new materials industry in Yongzhou, and it will also help accelerate the process of replacing imported high-end PI films with domestically produced ones in China. As the core project of this agreement, this high-end PI film project is aimed at achieving a high standard of quality and features a comprehensive layout. It aims to establish a modern new materials industry base that integrates production, research and development, sales, and equipment manufacturing. The focus is on the research and development as well as large-scale production of high-end electronic-grade PI films, with an intended annual production capacity of 5,000 tons. Once the project is completed and reaches full production capacity, it is expected to generate an annual output value of 2 billion yuan. It will serve as a key driver for the development of the regional new materials industry, further improving the structure of China’s PI film industry chain. At the technical level, the project will employ advanced industry processes such as cast coating or biaxial stretching. These two methods can be flexibly used to produce high-end PI films of various specifications; they enable precise control over film thickness, ensuring product stability, while also improving production efficiency. This approach is designed to ensure that the product performance meets international standards for similar products, thereby breaking through the technological and export restrictions imposed by developed countries in this field.
