September 24, 2024 – Zhejiang Changyang Technology Co., Ltd., a wholly-owned subsidiary of Changyang Technology Group, celebrated the groundbreaking ceremony of its 100,000 square meter annual production capacity project for Colorless and Transparent Polyimide (CPI) Film within the Zhoushan High-tech Industrial Park. This marks another significant milestone for Changyang Technology in the realm of flexible display materials.
The project, announced on April 25th, entails an investment of 302 million yuan by Zhejiang Changyang, aimed at expanding business scale and optimizing product mix. With an anticipated completion timeframe of 24 months, the focus lies in manufacturing CPI films that boast colorless transparency, high optical performance, mechanical strength, and chemical stability. Renowned for their flexibility and high light transmittance, these films serve as crucial raw materials for cover plates, substrates, and touch components in flexible display structures, particularly exhibiting immense market potential in foldable screen applications.
According to Color Masterbatch Industry Network, the demand for CPI films is escalating alongside the rapid advancements in flexible display technology. Changyang Technology, a prominent player in the optical film new materials industry since its establishment in 2010, has established industrial bases in Ningbo, Hefei, and Zhoushan. After entering the reflective film market in 2012, the company filled a domestic gap through technological breakthroughs, successfully breaking Japan and Korea’s technological monopoly in this field. By 2017, it surpassed Toray of Japan to become the global market leader, with its market share reaching a new high of 62% in 2023, further solidifying its position as the top player in the global optical reflective film segment.
Since 2018, Changyang Technology has actively ventured into the CPI film domain, mastering critical technologies from monomer polymerization to film processing. Its products excel in key indicators such as tensile strength, elongation at break, high transparency, and low haze, positioning the company to potentially disrupt the technological monopoly held by overseas enterprises in CPI films. As the first domestic enterprise poised to achieve large-scale production of CPI films, this achievement will provide robust support for China’s flexible display technology innovation, driving continuous development and progress across the industry.
