PI film
PI film (polyimide film) is a high-performance film made from polyimide resin via casting and imidization. It offers excellent high- and low-temperature resistance, electrical insulation, mechanical strength, uniform thickness, dimensional stability, and radiation resistance. The film can be slit, die-cut, or laminated, making it suitable for applications in FPCs, electronics, aerospace, new energy, and more.
