R-Thermosetting POLYIMIDE Powder

Quality characteristics

Beside our regular thermosetting PI-s powder, we have added a reprocessed thermosetting Polyimide powder to our portfolio. The R-Thermosetting Polyimide powder has a high heat resistance, excellent mechanical and electrical properties, low heat expansion and excellent chemical resistance and finds its application as a filler e.g., for compounding with PTFE Fluorpolymer.


As recycling is a sustainable process it is good for the environment.

Reprocessed Polyimide Powder is mainly used as a filler e.g., for compounding with PTFE Fluorpolymer.

Our thermosetting rPI powder can be used in the following industries:

  • For the Glass Container Industry parts
  • PTFE compounding (as filler)
  • Compounding with thermosetting plastics
  • Compounding with other thermoplastic polymers


We offer

Two grades with different particle sizes of reprocessed thermosetting Polyimide Powder are available: Dexnyl® rPI-s 30µ and 50µ.
