PI film production line

Polyimide (PI) is currently one of the materials with excellent neutral properties in organic polymer materials, widely used in fields such as aerospace, microelectronics, liquid crystals, separation membranes, etc. It is listed as one of the promising engineering plastics in the 21st century. PI film is one of the world's high-performance thin film insulation materials, and together with carbon fiber and aramid fiber, it is known as one of the three key bottleneck polymer materials for the development of high-tech industries in China. According to its use, PI film can be divided into electrical grade PI film with insulation and heat resistance as the purpose, and electronic grade PI film with high flexibility, low coefficient of expansion and other performance requirements.

With the development of aerospace, automotive, and 5G communication, the application of PI will continue to expand. The demand for high-performance polyimide films in the downstream market of China's polyimide film industry is also increasing. It can be expected that in the context of upgrading China's industrial structure and domestication of key materials, there is a huge market space for the import substitution of high-performance PI films, which is an opportunity for the development of PI films in China.

The polyimide film, known as the "golden film", has excellent performance and is widely used in space technology, insulation of F and H-class motors and electrical appliances, FPC (flexible printed circuit board), PTC electric heating film, TAB (pressure-sensitive tape substrate), aerospace, aviation, computer, electromagnetic wire, transformer, audio, mobile phone, computer, smelting, mining electronic components industry, transportation, atomic energy industry and other electronic and electrical industries.
