PMDA-based polyimide resin 005

PIR-005 is unfilled PMDA/ODA-based polyimide resin powder, 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: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
