Market snapshot
Listing priceUSD/kg; dated snapshotsNot documented$139.98/kg median; $119.98–$174.17/kg across 5 dated product listings
Identity & Market
Base polymer / chemistryAramid-fibre reinforced polyamide[1]Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[2]
Densityg/cm³Not documented1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[2][3]
Typical priceUSD/kgNot documented1 kg-equivalent spools span 93–174; the middle of the market is about 140[4][5][6][7]
Price range across brandsUSD/kgNot documented93-174 across brands and formats; Polymaker Fiberon PPS-GF20 93 at 3 kg, IEMAI 3D CF-PPS 131 at 750 g, LEHVOSS Luvocom 3F PPS CF 9938 164 at 2.3 kg, Bambu Lab PPS-CF 174 at 750 g[4][5][6][7]
Market availability1–5Special order, 1–2 makers worldwide — no aramid-filled nylon filament was found in any catalogue searched; the aramid filaments that do exist in the retail market use an ASA matrix[4][8]Available from several mainstream brands[4][5][6]
Spool sizes & diametersNot documented1.75 mm; 0.5 kg spools[4]
Typical applicationsNot documentedChemical and automotive parts needing PPS chemistry with structural stiffness[2]
Printing Parameters
Enclosure / chamber requirement1–5Enclosure required (passive) — as for every nylon[1]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[2]
Overall printing difficulty1–5Not documentedExpert / industrial hardware only[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — no aramid-filled nylon datasheet was obtainable; Polymaker measures about 9 h of brass nozzle life on its fibre-filled nylons[9]Hardened steel required[2]
Abrasiveness1–5Highly abrasive — fibre-reinforced nylon composite[9]Highly abrasive — standard CF composite[2]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles; nylon already needs a drybox and Prusa names kevlar among the fibres that raise nozzle-clogging risk[10]High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[11][10]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %) — the polyamide matrix governs uptake[12]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[2][3]
Equilibrium moisture content at ~50 % RH%Not documented0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[2][3]
Effect of moisture on strengthPolymaker's printed dry-versus-wet blocks for its CoPA nylon show what conditioning does to the family: tensile 78.0 → 34.3 MPa and modulus 2703 → 724 MPa, with notched Charpy rising 6.9 → 27.7 kJ/m². Fibre reinforcement reduces but does not remove the effect[13][14]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[2]
Mechanical Properties
Tensile strength (XY)MPaNot documented59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[2][3]
Young's modulusMPaNot documented5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[2][3]
Elongation at break%Not documented1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[2][3]
Charpy impact, notchedkJ/m²Not documented5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[2][3]
Layer adhesion / Z tensileMPaNot documented32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[2][3]
Brittleness1–5Not documentedVery brittle — cracks or shatters easily; elongation at break 1.4 %[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[15]
Creep resistance / sustained load1–5Not documentedExcellent — 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[15][16][2]
Elasticity / flexibility1–5Not documentedRigid[2]
Z strength as % of XY%Not documented54 (PPS-CF10) and 36 (PPS-GF20), printed[2][3]
Thermal Properties
HDT at 0.45 MPa°CNot documented252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[2][3]
HDT at 1.8 MPa°CNot documented133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[2][3]
Glass transition (Tg)°CNot documented97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[2][3]
Melting point / Vicat°CNot documented279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[2][3]
Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[15]
Environment & Chemical
Chemical resistanceNot documentedOutstanding — PPS resists essentially all solvents below 200 °C[11]
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[2][3]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[17]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[17]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[17]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[17]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[17]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[17]Ventilated room or enclosure recommended[17]
Dust & fibre handling hazardNot documentedFibre is bound in the matrix; sanding dust should not be inhaled[2]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[18]None — PPS does not dissolve in any known solvent below 200 °C.[19][20]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[18]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[20]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[18]None — no solvent welds or smooths PPS.[19]

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.
