Polyetherketoneketone (PEKK) resins are one of the highest performing thermoplastics on the market. With a unique combination of mechanical strength and flexibility, it can fulfill the needs of even the most demanding projects. Our PEKK filament offers additional chemical resistances and low-flammability traits that make it perfect for tasks that require high-temperature exposure. Contact us to learn more about PEKK filaments and their wide range of uses.

PEKK is a high-temperature polymer that offers an interesting blend of exceptional properties and printability when compared to other materials in its class. While it may have slightly lower heat resistance than PEEK due to the lower melting point, it still has outstanding mechanical properties and chemical resistance. This makes it ideal for many of the same applications (aerospace, automotive, biomedical, etc.).
PEKK, like most polymer materials, inherently takes up moisture from the surrounding atmosphere due to the nature of its chemistry. When most polymers are extruded with high moisture content, the chains in the polymer will break. When this happens, you may notice a change in viscosity and melt strength of the melted polymer. An obvious sign of your filament being too wet is popping noises as the material is extruded, the moisture in the material vaporizing. PEKK is shipped in vacuum-sealed bags to prevent moisture uptake during shipping and storage.
With PEKK being such a high-temperature polymer, especially when compared to other FDM materials, special considerations must be made for printing. Check with your printer manufacturer to be sure that your printer can handle the higher heats required to print this material. While smaller parts may be achievable without a heated chamber, it is still generally recommended when printing this material.
PEKK Filament is proudly made in the USA to the tightest diameter tolerance on the market. Filamatrix filaments are designed and developed by engineers with 50+ years of experience in plastic extrusion. All Filamatrix products are repeatedly tested for color uniformity and physical properties through an in-house print lab, consisting of numerous printer manufacturers. Physical properties of printed test bars are checked in an outside, certified lab.
