FPC Polyimide Film has lower shrinkage and good adhesion under the base of polyimide film HN, widely used in manufacturing flexible printed
circuit board(FPC), and other fields requiring lower shrinkage and good adhesion.
Characters:
* Class H insulation and heat resistance. and can work for a long time at 200℃.
* Execellent dielectric performance.
*Higher mechanical strength, better tear resistance and flexibility.
*Supplied with different width(5mm-1040mm) and thickness(0.0125mm--0.20mm)
NOTE: normal color of this material is light--dark yellow. Please contact us for color requests of black,red,green,transparent,etc.
