ThermaX™ PPSU 3D Printing Filament

Polyphenylsulfone (PPSF or PPSU) is a high-temperature aromatic sulfone polymer. Long considered to be one of the highest performance polymers in the plastics world. PPSU has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, industrial, medical, semi-con applications. Previously only available to Stratasys® customers – now you can print with this ultra performance polymer.

Benefits of ThermaX™ PPSU:

  • Very high thermal properties superior to Ultem™ 1010

  • Tg of 220°C and HDT of 205°C

  • High Environmental Stress Crack Resistance (ESCR)

  • Sterilization capable, including EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization

  • Exceptional strength and modulus, even at elevated temperatures

  • Outstanding impact resistance

  • Highly resistant to even large (10 Mrd) doses of gamma radiation

  • Resists most common automotive fluids including gasoline, antifreeze, transmission fluids, motor oils, power steering fluid, windshield washer fluid (ESCR, 24 hrs, 100°C)

  • Inherently flame retardant with low smoke evolution and low smoke toxicity

  • Excellent dimensional stability with low creep sensitivity, low and uniform coefficient of thermal expansion, and highly reproducible part-to-part dimensions.
