ThermaX™ PSU

3DXTech
$80.00

Polysulfone (PSU) is a high-temperature aromatic sulfone polymer. PSU has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, food service, industrial, plumbing, medical, semi-con applications.

Attributes of Firewire® Polysulfone (PSU) include:

  • Very high thermal properties with a Tg of 187°C and HDT of 172°C [Superior to ULTEM™ 9085]
  • Excellent hydrolytic resistance
  • High Environmental Stress Crack Resistance (ESCR)
  • Highly resistant to gamma radiation
  • Sterilization suitable - including EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization
  • Resists most common automotive fluids, including gasoline, antifreeze, transmission fluid, motor oil, power steering fluid, windshield washer fluid
  • Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions

        ThermaX™ PSU is an excellent alternative to ULTEM™ 9085:

        Superior thermal properties (higher Tg and HDT) allow for higher strength and stiffness at elevated temperatures
        Lower cost per kg and lower density (more filament per kg)

        Filament Specifications:

        • Diameter: 1.75mm (+/- 0.05mm)
        • Density: 1.24g/cm3

        Recommended Print Conditions: (starting points)

          • Extruder Temp: 350 - 380°C (all-metal extruder)
          • Bed Temp: 140-160°C
          • Bed Prep: Nano Polymer Adhesive , ULTEM™ Tape, Polyimide Tape, Lightly sanded FR4 or Perf board.
          • Other: No cooling fan, Print speeds of 15-70mm/sn (70 maximum, speeds will vary depending on part geometry and results) We recommend printing within a heated enclosure or in a warm build environment.

        PSU is sold by Solvay under the tradename Udel and by BASF under the tradename Ultrason S.
