005 polyimide powder with PMDA structure
77

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
