| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Very high (>2 %) — Polymaker's own wet-state specimens reached 6.16 % moisture content after 48 h immersion at 60 °C[1][16] | Low — 0.25 % saturated at 25 °C / 55 % RH (Bambu Lab); Prusa measures 0.15 % after 7 days at 22 % RH. Polymaker nonetheless calls PC highly hygroscopic in service[6][5][4] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.25 saturated at 25 °C / 55 % RH (Bambu Lab); 0.15 after 7 days at 24 °C / 22 % RH (Prusa)[6][5] |
| Drying temperature & time | 100 °C for 8 h (Polymaker CoPA)[1] | 80 °C for 8 h (Bambu Lab); 75 °C for 6 h (Polymaker); 70–80 °C for 6–8 h (Polymaker material guide)[6][3][4] |
| Symptoms when wet | Popping and cracking during extrusion, then hard-to-diagnose defects[18] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[16] |
| Effect of moisture on strength | Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[1][18] | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[4][16] |
| Storage requirement | Polymaker states CoPA must always be stored and used below 20 % relative humidity[1] | Airtight containers with desiccant to prevent reabsorption[4] |
| Hydrolysis at melt temperature | Polymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[1][20] | Not documented |

| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[27] | Ventilated room or enclosure recommended[27][13] |
| Post-Processing | ||

| Solvents & Solubility | ||
| Soluble in | Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[28] | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[29] |
