Polyimide (PI) is a polymer of imide monomers. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. In flexible PCB and rigid-flex PCB, polyimide plays the roles of FCCL, coverlay and stiffener.
