Polyimide Film (PI Film) is a high-performance polymer material renowned for its exceptional thermal stability, mechanical strength, and electrical insulation properties. Composed of aromatic heterocyclic structures, it is synthesized through a condensation reaction of dianhydride and diamine monomers. PI film is widely recognized as a "gold-standard" material in extreme environments due to its ability to withstand temperatures ranging from -269°C to +400°C without significant degradation. Its versatility makes it indispensable in industries requiring reliability under harsh conditions.
