Applications of Polyimide Film #4

PI film material has obvious performance advantages and wide electronic application fields.

PI film is one of the best insulating materials in the world. Among PI materials, PI film has special properties such as high strength, high toughness, wear resistance, high temperature resistance and corrosion prevention, and has become one of the important upstream raw materials in electronic and motor fields.

PI film can be divided into electrical grade with insulation and heat resistance as main performance indexes and electronic grade with high flexibility and low expansion coefficient. As a special engineering material, electronic grade PI film used in electronic information products is called ‘golden film’.

Electronic grade PI film has a wide range of application scenarios. Due to the outstanding advantages of polyimide PI in performance and synthesis, the main applications of electronic grade PI film include: flexible cover plate and cover plate material, COF flexible substrate, FPC substrate and cover layer material, raw film material of graphite heat sink and MPI for 5G application, etc.
