Polyimide film(HN)

NAME:Polyimide film(HN)  ID:Polyimide Film Series Supplier
DETAILS:

Polyimide Film  is made from the synthetic polymer by pyromellitic anhydride and diamino phenyl ether via salivating and continuous bi-orientation drawing,

and dehydrating for imidizatiion. 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 ,electronic industry, and other fields.

Characters:

* Class H insulation and heat resistance,can work for long time under 200C

* Excellent dielectric performance.

*Higher mechanical strength, better tear resistance and flexibility.

*Supplied with different width(5mm1040mm),thickness(0.0125mm—0.20mm) and parts such as discs,dots,tubes,etc.

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