EPS 150 vs GB/T 10801.1 Type IV
Polymer · grade comparison
EPS 150 and GB/T 10801.1 Type IV are both polymer grades. GB/T 10801.1 Type IV is the stronger of the two: tensile strength 0.42 MPa (0.0609 ksi) against 0.3 MPa (0.0435 ksi) for EPS 150, about 40% more. EPS 150 is lighter (0.03 g/cm³ vs 0.04 g/cm³ for GB/T 10801.1 Type IV) and GB/T 10801.1 Type IV is stiffer (0.01 GPa vs 0.01 GPa). On the shop floor, EPS 150 welds better (fair vs poor).

EPS 150 vs GB/T 10801.1 Type IV: 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.
