| Price range across brandsUSD/kg | Not documented | 223-733 across brands; IEMAI 3D 223 at 1 kg, 3DXTech ThermaX PPSU 250 at 500 g, 3D4Makers 425 at 750 g, Kimya PPSU-S 733 at 500 g[4][5][6][7] |
| Market availability1–5 | Not documented | Niche, a handful of specialist brands[4][5][6] |
| Spool sizes & diameters | 1.75 mm diameter, 1 kg spool.[8] | 1.75 and 2.85 mm; 200 g to 750 g spools[4][5][6] |
| Typical applications | Manufacturer applications include footwear, sports equipment and cushioning.[1] | Steam-sterilisable medical and dental tooling, and aircraft interior parts[2] |
| Printing Parameters | ||
| Nozzle temperature°C | 230–260 °C; 240 °C recommended.[1] | Not documented |
| Bed temperature°C | 60–90 °C[1] | 130–150 (3DXTech)[2] |
| Enclosure / chamber requirement1–5 | Not documented | Actively heated chamber required[9][10] |
| Part cooling fan | 10–50% fan recommended; mechanical-test specimens used 50–100%.[1] | Not documented |
| Bed surface & adhesion aid | PEI build plate[1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[1] | Not documented |
| Warping tendency1–5 | Not documented | Severe — heated chamber needed[9] |
| Overall printing difficulty1–5 | Not documented | Expert / industrial hardware only[9][10] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Not documented | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[9] |
| Abrasiveness1–5 | Not documented | Non-abrasive when unfilled[2] |
| Nozzle clog risk1–5 | Not documented | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[11] |
| Moisture Behaviour | ||
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[12] |
| Drying temperature & time | 70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[1] | Not documented |
| Effect of moisture on strength | Not documented | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[11] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | >16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[1] | 55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[2][3][12] |
| Young's modulusMPa | Not documented | 2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[2][3][12] |
| Elongation at break% | >520% printed XY, GB/T 1040; manufacturer lower bound.[1] | 3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[2][3][12] |
| Flexural strengthMPa | Not documented | 110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[2][3][12] |
| Flexural modulusMPa | Not documented | 2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[2][3] |
| Other impact data | Not documented | Izod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[3][12] |
| Layer adhesion / Z tensileMPa | 7.5 MPa printed Z, GB/T 1040 (manufacturer test)[1] | Not documented |
| Brittleness1–5 | Not documented | Brittle — snaps with little warning[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[8] | Rockwell M86 on printed PPSF (ASTM D785, Stratasys); M96 on extruded PPSU stock (and an unlabelled 123)[3][12] |
| Creep resistance / sustained load1–5 | Not documented | Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[3][12] |
| Elasticity / flexibility1–5 | Not documented | Rigid[2] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 190 (printed XY, ISO 75 at 0.45 MPa, 3DXTech)[2] |
| HDT at 1.8 MPa°C | Not documented | 189 (printed, ASTM D648 at 264 psi, Stratasys PPSF); 207 on extruded stock, converted from 405 °F[3][12] |
| Glass transition (Tg)°C | Not documented | 230 (DSC) — the highest glass transition in the dataset[2] |
| Melting point / Vicat°C | 110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[1] | Not documented |
| Continuous service temperature°C | Not documented | 149 long-term service on extruded PPSU stock, converted from 300 °F[12] |
| Thermal expansion (CTE)µm/m·K | Not documented | 55.0 (printed PPSF, ASTM D696; source states 5.5e-5 mm/mm/°C) and 55.8 on extruded stock (ASTM D696, from 3.1e-5 in/in/°F)[3][12] |
| Flammability / UL 94 | Not documented | UL 94 V-0 at 1.5 mm, rated on the base resin[2] |
| Environment & Chemical | ||
| Chemical resistance | Not documented | Withstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[2][3] |
| Electrical & ESD properties | Not documented | Volume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[3] |
| Health & Safety | ||
| Fume toxicity1–5 | Not documented | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[13] |
| Ventilation / filtration requirement1–5 | Not documented | Ventilated room or enclosure recommended[13] |
| Solvents & Solubility | ||
| Soluble in | Not documented | Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[14] |
| Softened or crazed by | Not documented | MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[14] |
| Solvent welding & smoothing agent | Not documented | Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[14] |
Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
