Polyimide machined parts & shapes

Polyimide Parts & Shapes  are made of PIR-002 unfilled polyimide resin powder with excellent physical properties,or filled with graphite,glass fiber,

PTFE,MoS2,etc. based on final uses,widely used from automotive industry and  aerospace to  industrial applications  and office  machines,etc.

Characters:

* Supplied in different machined parts &shapes:rods, sheets, rings, seals, bushings, rollers, bearings,

  Washers, pads, etc.

* Low wear and friction

* Excellent heat resistance.

* Excellent dielectric performance.

* Excellent chemical resistance.

*Higher mechanical strength, better tear resistance.

*Machinable with standard tools
