PA9T ESD vs PA9T GF33
Polymer · PA9T grade comparison
PA9T ESD and PA9T GF33 are two grades of the same polymer grade, PA9T: ESD (ESD / conductive) versus GF33 (GF30–33). The chemistry is identical, so every difference below comes from the condition. PA9T GF33 is the stronger of the two: tensile strength 195 MPa (28.3 ksi) against 150 MPa (21.8 ksi) for PA9T ESD, about 30% more. PA9T GF33 is the more ductile: elongation 2.5% versus 2% for PA9T ESD. PA9T ESD is stiffer (11 GPa vs 10 GPa) and PA9T ESD conducts heat better (0.55 W/m·K vs 0.35 W/m·K). On the shop floor, PA9T GF33 welds better (good vs poor).
PA9T GF33Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
PA9T ESD vs PA9T GF33: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

PA9T ESD vs PA9T GF33 — frequently asked
Is PA9T GF33 stronger than PA9T ESD?
Yes. PA9T GF33 has a typical tensile strength of 195 MPa (28.3 ksi) against 150 MPa (21.8 ksi) for PA9T ESD — about 30% more.
Which grade does FabDigit quote by default, ESD or GF33?
NEAT is the default PA9T condition in the FabDigit quote flow (neither ESD nor GF33). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, PA9T ESD or PA9T GF33?
PA9T GF33, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for PA9T ESD; for welding the order is PA9T GF33 first (good, 55/100) then PA9T ESD (poor, 25/100).
