HN Polyimide Film

Polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. It possesses a unique combination of properties, including excellent electrical and physical properties over a wide range of temperatures. It also has excellent chemical resistance; there are no known organic solvents for the film, and is self extinguishing with UL-94 V-0 rating. Making it an excellent choice for a variety of applications in many different industries, including wire and cable, coil insulation, substrates for flexible printed circuits, motor slot liners, magnet wire insulation, transformer and capacitor insulation.
