Supply BTDA-based polyimide resin,polyimide for super abrasive tool,non-thermalplastic polyimide

BTDA-based polyimide resin 004

PIR-004 is unfilled BTDA-based polyimide resin powder , widely used as matrix resin for shapes,components and parts with excellent physical properties, and also for coating,membrane,etc.

(BTDA is abbr.:3,3’4,4’-Benzophenonetetracarboxylic dianhydride)

Base Structure:

Characters:

* Good compatibility with fillers:graphite,glass fiber,PTFE,MoS2,etc.

* Low wear and friction * Excellent heat resistance.

* Excellent dielectric performance. * Excellent chemical resistance.

*Higher mechanical strength, better tear resistance.*Machinable with standard tools
