EMAA vs EVA
Polymer · grade comparison
EMAA and EVA are both polymer grades. EMAA is the stronger of the two: yield strength 10 MPa (1.45 ksi) against 7 MPa (1.02 ksi) for EVA, about 43% more; tensile strength follows at 30 MPa (4.35 ksi) vs 17 MPa (2.47 ksi). In exchange, EVA is the more ductile: elongation 780% versus 400% for EMAA, and EMAA is harder (55 Shore D vs 32 Shore D). EMAA is stiffer (0.2 GPa vs 0.05 GPa) and EVA conducts heat better (0.34 W/m·K vs 0.25 W/m·K). On the shop floor, EVA sits in a lower cost tier (budget, $) than EMAA (premium, $$$).
EMAAChoose it when strength drives the design.
EVAChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
EMAA vs EVA: 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.

EMAA vs EVA — frequently asked
Is EMAA stronger than EVA?
Yes. EMAA has a typical yield strength of 10 MPa (1.45 ksi) against 7 MPa (1.02 ksi) for EVA — about 43% more. Tensile strength is 30 MPa (4.35 ksi) vs 17 MPa (2.47 ksi).
Which is cheaper, EMAA or EVA?
EVA is the lower-cost material: it sits in the budget tier ($) while EMAA 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, EMAA or EVA?
EMAA, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for EVA.
