PIR-004 polyimide resin powder is unfilled thermoset polyimide with BTDA structure, widely used as matrix resin for shapes,components and parts with excellent physical properties, and also for coating,membrane,etc.
Note:1.Different polyimide types also available with different structures
2.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
