Rebond Foam vs Reticulated PU Foam
Polymer · grade comparison
Rebond Foam and Reticulated PU Foam are both polymer grades. Reticulated PU Foam is the more ductile: elongation 180% versus 60% for Rebond Foam. Reticulated PU Foam is lighter (0.03 g/cm³ vs 0.08 g/cm³ for Rebond Foam) and Rebond Foam is stiffer (8×10⁻⁴ GPa vs 3×10⁻⁵ GPa). On the shop floor, Reticulated PU Foam welds better (good vs poor) and Rebond Foam sits in a lower cost tier (standard, $$) than Reticulated PU Foam (high, $$$$).
Rebond FoamChoose it when cost is the deciding factor.
Reticulated PU FoamChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Rebond Foam vs Reticulated PU 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.

Rebond Foam vs Reticulated PU Foam — frequently asked
What is the difference between Rebond Foam and Reticulated PU Foam?
Rebond Foam and Reticulated PU Foam are both polymer grades. Reticulated PU Foam is the more ductile: elongation 180% versus 60% for Rebond Foam. Reticulated PU Foam is lighter (0.03 g/cm³ vs 0.08 g/cm³ for Rebond Foam) and Rebond Foam is stiffer (8×10⁻⁴ GPa vs 3×10⁻⁵ GPa).
Which is cheaper, Rebond Foam or Reticulated PU Foam?
Rebond Foam is the lower-cost material: it sits in the standard tier ($$) while Reticulated PU Foam is high ($$$$). 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, Rebond Foam or Reticulated PU Foam?
Rebond Foam, by a small margin. Both rate very good for machinability — 80/100 against 75/100 for Reticulated PU Foam; for welding the order is Reticulated PU Foam first (good, 60/100) then Rebond Foam (poor, 15/100).
