PEKK filament 1.75mm 500g

PEKK is a semi-crystalline thermoplastic in the polyaryletherketone family. This material has a very good layer adhesion and dimensional stability. This neat PEKK enables semi-crystalline parts with no warping.

Features:
- Outstanding temperature and chemical resistance
- Excellent mechanical properties
- Flame retardant
- Unique tribological properties

Additional info:
Recommended temperature for heated bed is ≥110°C. Adhesion is possible on different surfaces. PEKK can be used on desktop FDM or FFF technology 3D printers able to reach the required temperatures. Dry the spool before printing: 6-8 hours at max. 120°C or 4 hours at 130°C.

Storage:
Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
