Hefei Guofeng Advanced Basic Materials Technology Co., Ltd.
Guofeng Xianji Company, a wholly-owned subsidiary of Guofeng
New Material, is a high-tech enterprise specializing in the
R&D, production, sales, and service of high-performance
polyimide (PI) materials.
PI film, commonly known as the "gold film" in the industry,
is one of the polymer materials with the best comprehensive
performance. It exhibits excellent properties such as high
insulation, high heat resistance, high strength, and high radiation
resistance, earning it the reputation as a "problem-solving
expert." Alongside carbon fiber and aramid fiber, PI film is
recognized as one of the three bottleneck polymer materials
restricting the development of China's high-tech industries. Its
products are primarily used in high-tech fields such as power and
electrical engineering, energy and transportation, 5G
communication, electronic information, aerospace, and more.
The PI project is a key industrial initiative for Guofeng
New Material's industrial transformation and upgrading. In March
2019, Guofeng New Material established a Polyimide Branch, which
successively built and put into operation four thermal production
lines in the Hefei High-Tech Zone. To further expand production
scale and diversify the product portfolio, Guofeng New Material
invested 600 million yuan in May 2021 to register and establish
Hefei Guofeng Advanced Basic Materials Technology Co., Ltd. This
new company is constructing seven thermal production lines and one
chemical production line (imported) in the Hefei Xinzhan District.
With a total PI film production capacity of 1,600 tons, Guofeng
ranks among the top domestic producers.
The company boasts a team of highly qualified technical and
managerial professionals, adhering to a combination of independent
innovation and industry-academia-research collaboration. It has
established multiple experimental facilities, including a PI
synthesis laboratory and a PI pilot production line. Additionally,
the company has set up joint laboratories with the University of
Science and Technology of China and Harbin Institute of Technology,
focusing on PI frontier technologies and critical challenges. These
collaborations aim to advance key core technologies and
industrialize PI materials for applications in flexible circuits,
flexible displays, integrated circuit packaging, and other fields.
The company has successfully overcome multiple key technologies in
PI product preparation, with several electronic-grade PI films
achieving mass production and gaining widespread customer
recognition. This has effectively addressed the long-standing
"bottleneck" issue of China's reliance on imported high-end PI
films.
To date, the company holds 28 authorized invention patents
and 27 authorized utility model patents for its polyimide films.
The Guofeng PI project has been included in Anhui Province's key
manufacturing initiatives for addressing shortcomings in
industry-academia-research applications and critical common
technology breakthroughs, as well as in Hefei's strategic new
materials industry plan. In 2022, the company was recognized by the
Hefei Development and Reform Commission as a key enterprise in the
new display industry chain. The polyimide films produced by the
company have obtained UL certification in the United States, and
among them, the "GB-type polyimide black film for precision circuit
boards" has been selected for the first batch of new materials list
in Anhui Province.
