HN Polyimide film

Polyimide Film is made from the synthetic polymer by pyromellitic anhydride and 4,4'-Oxydianiline through salivating and continuous bi- orientational drawing, and dehydrating for imidization. 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) and parts:disc, dot, tube, etc.

NOTE: normal color of this material is light--dark yellow. Please contact us for color requests of: black,green,red,transparent,etc.
