| Bed temperature°C | 95 ± 10 (Prusament)[1] | Not documented |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[13][14] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3] |
| Part cooling fan | Off — Prusa runs 0 % except 100 % on bridges[1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][15] | Not documented |

| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[1][12] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4] |

| Effect of moisture on strength | Not applicable in practice at 0.11 % equilibrium uptake[1] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3] |
| Storage requirement | No special storage needed[1] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 46.6 ± 1.3 filament tensile yield (Prusament, ISO 527) — more than double the carbon-fibre grade's 21[1][12] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4] |

| Elongation at break% | Not documented | 1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][4] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a glass-fibre PP filament[18] | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[19] |
| Creep resistance / sustained load1–5 | Not documented | Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[19][20][3] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | Not documented | 54 (PPS-CF10) and 36 (PPS-GF20), printed[3][4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 138.3 (ISO 75, 0.45 MPa)[1] | 252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[3][4] |

| Continuous service temperature°C | Not documented | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[19] |
| Environment & Chemical | ||
| Chemical resistance | Excellent against acids, alkalis and most solvents[14] | Outstanding — PPS resists essentially all solvents below 200 °C[17] |
| Water / humidity resistance in service1–5 | Excellent — essentially unaffected[1] | Not documented |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[21] | 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[21] |
| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[21] | Ventilated room or enclosure recommended[21] |
| Dust & fibre handling hazard | Glass fibre is bound in the matrix; avoid inhaling sanding dust[1] | Fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Solvents & Solubility | ||
| Soluble in | None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[22][23] | None — PPS does not dissolve in any known solvent below 200 °C.[24][25] |
| Softened or crazed by | Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[22] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[25] |
| Solvent welding & smoothing agent | None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[22] | None — no solvent welds or smooths PPS.[24] |
