PPSU

PPSU (Polyphenylsulfone) shows even beter results in impact resistance and chemical resistance than PEI. It can operate in temperatures up to 180°C. This filament is based on a PPSU grade from Solvay PPSU. PPSU is an excellent choice for under-hood automotive applications and medical devices requiring repeated steam sterilization. The hydrolysis resistance is excellent compared to other amorphous thermoplastics. Besides that, it also resists common acids and bases over a broad range of temperatures.

PPSU features:

  • High strength and toughness
  • Excellent chemical and thermal resistance
  • Good hydrolysis resistance
  • Flame retardant
  • Heat resistance up to 220°C

Additional info:

Recommended temperature for heated bed is >140˚C. Adhesion is possible on different surfaces. PPSU can be used on desktop FDM or FFF technology 3D printers able to reach the high required temperatures. Dry the spool before printing: +4 hours at max. 110°C.

Storage:

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