EPS 150 vs GB/T 10801.1 Type II
Polymer · grade comparison
EPS 150 and GB/T 10801.1 Type II are both polymer grades. EPS 150 is the stronger of the two: tensile strength 0.3 MPa (0.0435 ksi) against 0.25 MPa (0.0363 ksi) for GB/T 10801.1 Type II, about 20% more. In exchange, GB/T 10801.1 Type II is the more ductile: elongation 6% versus 2% for EPS 150. GB/T 10801.1 Type II is lighter (0.02 g/cm³ vs 0.03 g/cm³ for EPS 150) and EPS 150 is stiffer (0.01 GPa vs 0 GPa). On the shop floor, EPS 150 welds better (fair vs poor).
EPS 150Choose it when strength drives the design, or when it will be welded.
GB/T 10801.1 Type IIChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
EPS 150 vs GB/T 10801.1 Type II: 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.

EPS 150 vs GB/T 10801.1 Type II — frequently asked
Is EPS 150 stronger than GB/T 10801.1 Type II?
Yes. EPS 150 has a typical tensile strength of 0.3 MPa (0.0435 ksi) against 0.25 MPa (0.0363 ksi) for GB/T 10801.1 Type II — about 20% more.
Which is cheaper, EPS 150 or GB/T 10801.1 Type II?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, EPS 150 or GB/T 10801.1 Type II?
EPS 150. Its weldability rates fair (40/100) against poor (25/100) for GB/T 10801.1 Type II.
