Polyimide (PI) Film
Polyimide Film: The Backbone of New Technology
Polyimide films are crucial across diverse applications, ranging from Flexible Printed Circuit Boards (FPCB) to cutting-edge thermal management technologies. As smart devices evolve towards slimmer, more integrated designs, the flexibility and dependability of Polyimide film have become essential. It enables high-efficiency compact circuits in FPCBs, offers superior thermal conductivity in graphite sheets, and guarantees safety and performance in rechargeable batteries for electric vehicles, marking it as a central element in technological innovation.
Leading the Charge in 5G and Flexible Displays
Modified Polyimide Film (MPI) is essential for minimizing transmission loss in high-speed communications, enhancing 5G antenna performance and supporting seamless data transmission. As the industry shifts towards higher resolution displays and foldable devices, Polyimide film emerges as a benchmark, providing exceptional solutions for Chip on Film (CoF) applications and more.

PI films can withstand extreme temperatures ranging from near absolute zero to 400°C and can adapt to the most demanding manufacturing processes or ultimate use conditions. |
PI films are extremely isotropic and retain their original shape and form over a wide temperature range in both directions. Some of our films are specially engineered to minimize CLTE (Coefficient of Linear Thermal Expansion) so as to match that of copper, a key requirement for the FPCB industry. |
PI films are excellent electrical insulators that can be used in high-voltage environments in electronic devices for stability and electrical conductors for insulation. |

Due to their excellent bendability and dimensional stability, PI films are suitable for flexible/foldable applications and afford flexibility in PCB design. |
PI films are halogen-free and intrinsically flame retardants. Our films further display an excellent FST (Flame, Smoke and Toxicity) behavior required for AAD (Aeronautics Aerospace and Defense) applications. |
PI films display an all-around excellent chemical resistance to a variety of chemicals. |
