IXPE vs POE Foam
Polymer · grade comparison
IXPE and POE Foam are both polymer grades. POE Foam is the stronger of the two: tensile strength 2 MPa (0.261 ksi) against 0.35 MPa (0.0508 ksi) for IXPE, about 5.1 times as much. POE Foam is the more ductile: elongation 220% versus 150% for IXPE. IXPE is lighter (0.03 g/cm³ vs 0.15 g/cm³ for POE Foam) and POE Foam is stiffer (0.01 GPa vs 0 GPa). On the shop floor, IXPE machines more easily (excellent vs good), IXPE welds better (very good vs good), and IXPE sits in a lower cost tier (standard, $$) than POE Foam (premium, $$$).
IXPEChoose it when weight is the constraint, or when the part sees heat.
POE FoamChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
IXPE vs POE Foam: 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.

IXPE vs POE Foam — frequently asked
Is POE Foam stronger than IXPE?
Yes. POE Foam has a typical tensile strength of 2 MPa (0.261 ksi) against 0.35 MPa (0.0508 ksi) for IXPE — about 5.1 times as much.
Which is cheaper, IXPE or POE Foam?
IXPE is the lower-cost material: it sits in the standard tier ($$) while POE Foam is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, IXPE or POE Foam?
IXPE. Its machinability rates excellent (85/100) against good (60/100) for POE Foam; for welding the order is IXPE first (very good, 70/100) then POE Foam (good, 55/100).
