• High strength and toughness
  • Outstanding chemical resistance
  • Ease of processing
  • Wear Resistance


  • Cost
  • Anisotropic
  • High processing temperatures


Ketone-based resins such as polyetheretherketone (PEEK) are semi-crystalline engineering thermoplastics that can be used at high temperatures.

Other characteristics of PEEK include excellent chemical resistance, high strength and good resistance to burning. Although PEEK requires high processing temperatures, it can be processed using standard equipment.
