EVA Foam Sheet (Footwear Grade) vs PE Foam Board

Polymer · grade comparison

EVA Foam Sheet (Footwear Grade) and PE Foam Board are both polymer grades. EVA Foam Sheet (Footwear Grade) is the stronger of the two: tensile strength 2 MPa (0.29 ksi) against 0.35 MPa (0.0508 ksi) for PE Foam Board, about 5.7 times as much. EVA Foam Sheet (Footwear Grade) is the more ductile: elongation 250% versus 80% for PE Foam Board. PE Foam Board is lighter (0.03 g/cm³ vs 0.18 g/cm³ for EVA Foam Sheet (Footwear Grade)) and EVA Foam Sheet (Footwear Grade) is stiffer (0.01 GPa vs 0 GPa).

EVA Foam Sheet (Footwear Grade)Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

PE Foam BoardChoose it when weight is the constraint, or when the part sees heat.

EVA Foam Sheet (Footwear Grade) vs PE Foam Board — frequently asked

Is EVA Foam Sheet (Footwear Grade) stronger than PE Foam Board?

Yes. EVA Foam Sheet (Footwear Grade) has a typical tensile strength of 2 MPa (0.29 ksi) against 0.35 MPa (0.0508 ksi) for PE Foam Board — about 5.7 times as much.

Which is cheaper, EVA Foam Sheet (Footwear Grade) or PE Foam Board?

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.

When should I choose EVA Foam Sheet (Footwear Grade) over PE Foam Board?

Pick EVA Foam Sheet (Footwear Grade) when strength drives the design, or when the part is bent, formed or impact-loaded. Pick PE Foam Board when weight is the constraint, or when the part sees heat.
