PE Foam Board vs POE Foam

Polymer · grade comparison

PE Foam Board 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 PE Foam Board, about 5.1 times as much. POE Foam is the more ductile: elongation 220% versus 80% for PE Foam Board. PE Foam Board 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, PE Foam Board machines more easily (excellent vs good) and PE Foam Board sits in a lower cost tier (standard, $$) than POE Foam (premium, $$$).

PE Foam BoardChoose 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.

PE Foam Board vs POE Foam — frequently asked

Is POE Foam stronger than PE Foam Board?

Yes. POE Foam has a typical tensile strength of 2 MPa (0.261 ksi) against 0.35 MPa (0.0508 ksi) for PE Foam Board — about 5.1 times as much.

Which is cheaper, PE Foam Board or POE Foam?

PE Foam Board 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, PE Foam Board or POE Foam?

PE Foam Board. Its machinability rates excellent (88/100) against good (60/100) for POE Foam; for welding the order is PE Foam Board first (good, 60/100) then POE Foam (good, 55/100).
