6052 polyimide film is one of the earlier polyimide products. It was originally used as slot insulation and cable wrapping material for motors. After nearly 50 years of development, it has become one of the important raw materials in the electrical and electronic field.

PI film not only meets the basic physical performance requirements of various products, but also has special properties such as high strength, high toughness, wear resistance, high temperature resistance, and corrosion resistance. of high temperature insulating material. It has become one of the important upstream raw materials in the two fields of electronics and motors.

Widely used in aviation, aerospace, electrical and electronics, semiconductor engineering, microelectronics and integrated circuits, nanomaterials, liquid crystal displays, LED packaging, separation films, lasers, locomotives, automobiles, precision machinery and automated office machinery and other fields.

At present, there are about 50 PI film manufacturers of different scales in my country, of which about 80% are manufactured by the drooling process, and only a few are manufactured by the biaxial orientation process. The width of domestic PI film products is 1040mm, and the production capacity of a single production line is basically about 200t/y.

According to the application in different terminal electronic products, the thickness specification of PI film can be divided into 7.5μm, 12.5μm, 25.0μm and thick film, of which 12.5 μm or thinner PI film is used for handheld electronic products such as mobile phones and cameras. 25.0 is generally used for electronic products, automobiles, notebook computers and cover films with μm thick PI films, and thicker PI films are used for reinforcing plates.

The R&D and manufacturing technology of global high-performance PI film is completely monopolized by the United States, Japan and South Korea, mainly concentrated in DuPont, Yubu Xingsan, Zhongyuan Chemical, skckolon and other manufacturers, controlling about 90% of the global market share. The mid-1970s , Due to insufficient downstream market demand at that time, the PI film industry developed slowly, and the domestic production capacity of ordinary PI film for electrical insulation was only about 250t/y. Entering the 21st century, with the development of the domestic electronics industry, especially the rapid development of flexible copper clad laminates (FCCL), it has brought huge development space to the PI film market, and the market demand is increasing day by day.
