ThermaX™ PPE

ThermaX™ PPE-PS


ThermaX™ PPE-PS (Polyphenylene Ether + Polystyrene)

ThermaX™ PPE-PS polyphenylene ether alloy exhibits exceptional thermal, mechanical, and chemical resistance properties. Our PPE-PS filament is made from a UL94 V0 rated flame retardant base resin.  ThermaX™ PPE has been an ideal material for a wide array of applications in demanding markets such as aerospace, automotive, industrial, electronics, and telecommunications.  

Product attributes include:

  • High heat resistance - 120°C rated HDT at 1.8MPa
  • UV resistance suitable for outdoor applications (F1 rating per UL 746C)
  • Excellent chemical resistance to most aqueous solutions, detergents, acids and alkalis
  • Flame retardant - made using UL94 V0 rated resin (V-0 at 0.75mm, 5VB at 1.5mm, 5VA at 2.5mm)
  • Amorphous - low and near isotropic shrink rate
  • Stable in boiling water - excellent long-term hydrolytic stability
  • Very low moisture absorption
  • High-impact resistance suitable for industrial applications
  • Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Recommended Print Conditions:

  • Extruder Temp: 290-320°C (all-metal extruder)
  • Bed Temp: 90-110°C
  • Printer Chamber Temp:  50-80°C (if a heated print chamber is available on your printer)
  • Bed Prep: PEI Tape or Sheet, Glue Stick on Clean Glass
  • Nozzle / Layer Height:  We recommend that you print using a layer height that is 60% of your nozzle diameter.  So for example, a 0.4mm nozzle would be used to print a layer height of 0.24mm. 
  • Print speed:  Speeds of 70-90mm/s are routinely used with this material on a well-calibrated printer
