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 at 200C
|
|
* Excellent dielectric performance.
*Higher mechanical strength, better tear resistance and flexibility.
*Supplied with different width(3mm—1040mm),thickness(2um—250um) 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.
