Polyimide Film HN is the most common pyromellitic-structured polyimide film,made from the synthetic polymer by PMDA and ODA. It has excellent heat stability, mechanical and dielectric strength, radiation and chemical resistance, and able to be applied from -269℃(-452°F) to 400℃ (752°F), widely used in electrical and electronic industry,etc.
Characters:
* Class H insulation and heat resistance.
* Excellent dielectric performance.
*Higher mechanical strength, better tear resistance and flexibility.
*Good radiation and chemical resistance
*Supplied with different width(5mm-1040mm),thickness(0.0125mm-0.20mm)
Application: widely used in class H motors, transformers , wrapping of temperature-proofing magnet wire and polyimide adhesive tape,flexible printed circuit board, diaphragm,etc.
