| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High (0.8–2 %) — Prusa measures 0.46 % after 7 days at 22 % RH, but PA11 sits between PA12 and PA6 in the family[1][10] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4] |

| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Solvents & Solubility | ||
| Soluble in | Dissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[18][19] | None — PPS does not dissolve in any known solvent below 200 °C.[20][19] |
| Softened or crazed by | Mineral acids, oxidants, halogens and zinc chloride solutions attack the amide bond; ordinary solvents do not (BASF, PA6/66).[18] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[19] |
| Solvent welding & smoothing agent | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[18] | None — no solvent welds or smooths PPS.[20] |
