ABS GF10 vs ABS GF30
Polymer · ABS grade comparison
ABS GF10 and ABS GF30 are two grades of the same polymer grade, ABS: GF10 (10 % glass-fibre reinforced) versus GF30 (30 % glass-fibre reinforced). The chemistry is identical, so every difference below comes from the condition. ABS GF30 is the stronger of the two: tensile strength 95 MPa (13.8 ksi) against 65 MPa (9.43 ksi) for ABS GF10, about 46% more. In exchange, ABS GF10 is the more ductile: elongation 4% versus 2.3% for ABS GF30. ABS GF10 is lighter (1.09 g/cm³ vs 1.28 g/cm³ for ABS GF30) and ABS GF30 is stiffer (7.5 GPa vs 4 GPa). On the shop floor, ABS GF10 machines more easily (very good vs good).
ABS GF10Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
ABS GF30Choose it when strength drives the design.
ABS GF10 vs ABS GF30: 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.
