Hefei-made "Gold Film" Achieves Leading Position
On May 29, 2025, reporters learned from Anhui Guofeng New Material Co., Ltd. (hereinafter referred to as "Guofeng New Material") that the first batch of products from the chemical production line of the electronic-grade polyimide (PI) film material project has been successfully produced, marking the commencement of trial operations with material feed. Key technical indicators have reached the level of competing international products.

Picking up a foldable smartphone, turning on an ultra-thin TV, starting a new energy vehicle, or receiving satellite navigation signals—modern high-quality living is inextricably linked, moment by moment, to a thin “film.” Thanks to its exceptional resistance to high and low temperatures, electrical insulation, radiation resistance, and durability against various media, polyimide (PI) film ranks among the world’s best insulating materials in film form. It is widely used in 5G communication, new energy, electronic devices, aerospace, and other high-tech fields.

With its challenging manufacturing process, highly demanding applications, and premium cost, polyimide film is regarded as a “gold film” at the pinnacle of the materials pyramid. Yet, due to its complex production technology and extremely strict manufacturing standards, China long relied on imports for this critical material.
