Product overview

Kepstan® is a Polyetherketoneketone (PEKK) CoPolymer and is in the family of Poly Aryl Ether Ketone (PAEK) polymers. PEKK is synthesized in various formulations with individually unique properties. The PEKK formulations are expressed by the ratio of Terephthaloyl (T) to Isophthaloyl (I) moieties used during the synthesis that created the polymer. The T/I ratio affects PEKK’s melt point glass transition temperature and crystallization kinetics.

Use Kepstan® PEKK for high-performance applications: 

Semi-crystalline Kepstan® PEKK Seals via Fused Filament Fabrication on the miniFactory Ultra® 

Arkema and miniFactory have collaborated to develop materials and processes for 3D printing functional objects in semi-crystalline Kepstan® PEKK.  In this white paper, we will present the equipment, method, and results.

  • Additive Manufacturing of very demanding applications: low capital cost and efficient use of materials
  • Additively Manufactured Semi-crystalline PEKK vs conventional PEKK seals: performance and mechanical properties comparison
  • The outcome: High quality and a reproductive result of mechanical properties of AM PEKK with miniFactory Ultra 3D Printer.
