PIR-005 polyimide resin powder is unfilled polyimide with PMDA/ODA structure,Tg over 400℃, widely used as matrix resin for shapes,components and parts with excellent physical properties, that can work under harsh conditions due to its strong structure.
Note:1.Different polyimide types also available with different structures
2.PMDA/ODA abbr. of pyromellitic anhydride/4,4'-Oxydianiline
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
