3mil Polyimide Film

Our range of 3Mil Polyimide Film is synthesized by polymerizing 4-formic acid-2-anhydride of benzene(PMDA ) and 4.4-diamino-diphenyl-ether oxide (ODA) in strong polar solvents throughthe process of forming film and imine treatment at high temperature.
Appearance:Transparent or semi-transparent golden film with smooth and flat surface and without any needle cavities, bubbles or electrically conductive impurities.
Properties:
1) Excellent performance of insulation and mechanism
2) Excellent heat-resistance: as low as -269A C and as high as +260A C
3) Excellent chemical stability.
