3DXTech ThermaX PEKK-A (PolyEtherKetoneKetone) is made using Arkema Kepstan PEKK 60/40 Copolymer and is one of the highest performance in the materials in the world, while also being one of the easiest to print ultra-polymers.
THERMAX PEKK-A 3D PRINTER FILAMENT
Thermax PEKK-A is made using Arkema Kepstan PEKK and is one of the highest-performance polymers in plastics business. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK, it’s one of the easiest ultra-polymers to 3D print period. Developed in partnership with Arkema, a leading supplier of ultra-performance materials.
BENEFITS OF THERMAX PEKK-A:
- High thermal properties with a CUT of 260°C, Tg of 162°C, and a Tm of 335°C
- Substantially easier to 3D print than PEEK
- Wide processing window from 345-375°C
- Inherently flame-resistant (UL94 V-0)
- Low smoke generation
- Outstanding mechanical, thermal, and chemical resistances
ANNEALING THERMAX PEKK-A 3D PRINTED PARTS:
Parts printed with PEKK may be annealed after printing to ramp-up the crystallinity in the resin. This will maximize mechanical, thermal, and chemical resistance properties. Printed parts will be transparent golden in color and then turn an opaque tan color once annealed. If you do not anneal the PEKK parts, then the maximum use temperature is 150°C. If you do anneal, the maximum use temperature is 260°C. You can choose which route to go depending on the needs of your part.
- Place your part in an oven and raise the temperature to 130°C, allow to remain at that temperature for 30 minutes. Let it cool completely before handling.
