EtroX® I CM UHT natural


The premium product for highly demanding applications

Our premium material EtroX® I CM UHT was specially developed to meet the high demands of the electronics, aerospace and semiconductor industries. As a special pure polyimide, it withstands particularly high temperatures and offers a low water absorption of 0,06%. EtroX® I CM UHT can be used on long term with 300°C to design components that offer significant advantages over other thermoplastics.



  • Excellent thermo-oxidative stability (use up to 300°C)
  • high dimensional stability under heat
  • Extremely high heat resistance
  • Very low creep tendency
  • Nearly no moisture absorption


  • Semiconductor Industry
  • Semiconductor Back-End applications
  • Semiconductor Wafer Handling
  • Semiconductor High and low temperature
