Torlon 7130 vs Ultem 2300
Polymer · grade comparison
Torlon 7130 and Ultem 2300 are both polymer grades. Torlon 7130 is the stronger of the two: tensile strength 203 MPa (29.4 ksi) against 169 MPa (24.5 ksi) for Ultem 2300, about 20% more. Torlon 7130 is the more ductile: elongation 6% versus 3% for Ultem 2300. Torlon 7130 is stiffer (22.4 GPa vs 9 GPa) and Torlon 7130 runs hotter in service (250°C vs 170°C continuous). On the shop floor, Ultem 2300 machines more easily (good vs fair) and Ultem 2300 welds better (fair vs not recommended).
Torlon 7130Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Ultem 2300Choose it when the part is machined in volume, or when it will be welded.
Torlon 7130 vs Ultem 2300: 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.
