High Heat Polymères G-PAEK PEK

Technical data sheets

Gharda's G-PAEKTM product family is based on Polyether Ketone (PEK), a semi-crystalline polymer, with a high glass transition temperature of 152 °C and melting temperature of 372°C, the unfilled G-PAEKTM grades offer solutions to many high temperature and chemically resistant applications.

Additionally, we offer various value-added filled grades with improved strength for demanding opportunities that require high wear resistance. The heat deflection temperature of these grades can be as high as 360 °C, providing strength and stability in extreme conditions.

Unfilled grades are available as powders or pellets. Filled grades are available as dry blends and compounded pellets.

Advantages of G-PAEK TM polymer

  • Delivers up to two times the wear resistance of PEEK at high temperatures. 
  • Retention of mechanical and physical properties upto 30°C higher than PEEK supporting higher loads without permanent deformation. 
  • Improved compressive strength. 
  • A strong candidate for engine parts, subsea connectors and heat exchanger applications. 
  • Excellent gamma radiation resistance. 
  • Excellent hydrolysis resistance at high temperatures. 
  • Excellent high temperature performance for all mechanical properties. 
  • Excellent electrical performance at high temperatures. 
  • Excellent chemical resistance at high temperatures.
