Polyimide Film
Properties:
Polyimide film is synthesized by polymerizing PMDA(1,2,4,5-Benzene Tetracarboxylic Dianhydride (Pyromellitic dianhydride)) and ODA (4，4’-Diaminodiphenyl ether) in strong polar solvents through the process of forming film and imine treatment at high temperature, which possesses excellent physical, chemical, and electrical properties, atomic radiation resistant, solvent resistant, low & high temperature resistant. It performs successfully in the wide range of temperature as low as -260℃ and as high as +260℃. Because of its unique excellent properties, it is the most ideal choice in many applications.
Application:
1. For wrapping of magnet wire and cable, slot liner insulation, interlayer insulation in Motor, transformer etc.
2. The backing material for pressure-sensitive adhesive tape, FEP tape.
3. The substrates or overlay of Flexible Printed Circuits Board (F-PCB).
4. Polyimide tubing.
