EVA Foam Sheet (Footwear Grade) vs XPP
Polymer · grade comparison
EVA Foam Sheet (Footwear Grade) and XPP are both polymer grades. EVA Foam Sheet (Footwear Grade) is the stronger of the two: tensile strength 2 MPa (0.29 ksi) against 0.65 MPa (0.0943 ksi) for XPP, about 3.1 times as much. EVA Foam Sheet (Footwear Grade) is the more ductile: elongation 250% versus 25% for XPP. XPP is lighter (0.06 g/cm³ vs 0.18 g/cm³ for EVA Foam Sheet (Footwear Grade)) and XPP is stiffer (0.02 GPa vs 0.01 GPa). On the shop floor, EVA Foam Sheet (Footwear Grade) machines more easily (excellent vs good), XPP welds better (very good vs good), and EVA Foam Sheet (Footwear Grade) sits in a lower cost tier (standard, $$) than XPP (premium, $$$).
EVA Foam Sheet (Footwear Grade)Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
XPPChoose it when weight is the constraint, or when the part sees heat.
EVA Foam Sheet (Footwear Grade) vs XPP: 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.
