High performance and ease of process

Polyetherketoneketone (PEKK) is a polymer belonging to the polyaryletherketone family (PAEK), known for its excellent mechanical properties, high operating temperatures and chemical resistance. PEKK is among the first super polymers used on the market, a 3D printing material which is easier to process than other super polymers of the same family. With self-extinguishing properties and UL 94 V-0 classified, it offers the flexibility to produce translucent parts for a wide range of industrial applications.

Main characteristics of PEKK

High dimensional stability

Roboze PEKK has a lower melt viscosity than PEEK which determines a greater adhesion between the layers. This feature makes it mechanically resistant in three directions, by increasing the isotropy of the 3D printed parts.

Easy to process

Roboze PEKK material has a lower extrusion temperature than other super polymers. Its amorphous structure limits the warping phenomenon allowing to print medium-large parts. It does not require a heated working chamber to be printed.

Self-extinguishing material

PEKK is an inherently self-extinguishing 3D printing material, UL 94 V-0 classified. Its flame retardant properties make it suitable for applications subject to fire risks.
