| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
Low density (~0.035 g/cm³) soft closed-cell foam | Pick for lightest-weight cushioning, buoyancy and packaging voids where load-bearing is minimal. | 0.6 | 220 | 18 Shore A | |
non-cross-linked (uncured) EVA foam | Cheapest option for one-shot packaging and low-duty padding; accepts heat welding and remelt scrap but takes more permanent set. | 0.8 | 170 | 28 Shore A | |

Working with EVA Foam D60
Is EVA Foam easy to machine?
Die-cuts, skives, hot-wire and drag-knife cuts cleanly; for CNC use single-flute sharp routers at high feed with vacuum hold-down — dull tools smear and melt the cells.
Can EVA Foam be welded?
Joins by contact/hot-air welding, heat lamination or hot-melt/contact adhesive (chloroprene, PU); surfaces should be scuffed or flame/plasma treated for structural bonds.
Can EVA Foam be formed, bent or molded?
Compression-molded from bun stock or heat-formed at roughly 110–140 °C surface temperature; expect 2–4 % shrinkage after demold and allow for skin formation on molded faces.
What surface finishes work on EVA Foam?
Seal the open cells of cut edges with heat, plasti-dip or flexible PU/latex primer before painting; flexible acrylic or PU topcoats only — rigid paints crack on flexing.
EVA Foam chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| vinyl acetate (comonomer)higher VA = softer, more elastic foam | 15 – 30 | 20 |

| ZnO / zinc stearate (activator, kicker) | 0.5 – 3 | 1.5 |
| CaCO3 / talc fillercost/stiffness adjustment | 0 – 15 | 5 |
| pigment, antioxidant, processing aid | 0.5 – 4 | 2 |

EVA Foam D60 is typically used for shoe midsoles and insoles, sports and helmet padding, case and tool-tray inserts, packaging cushioning, low-load dust and splash gaskets and thermal insulation layers. In short: lightweight closed-cell EVA.
What is the tensile strength of EVA Foam D60?
EVA Foam D60 has a typical tensile strength of 1 MPa (0.16 ksi) — weaker than 85% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is EVA Foam D60 easy to machine?
Yes — machinability is rated excellent (85/100, better than 88% of polymer grades). Die-cuts, skives, hot-wire and drag-knife cuts cleanly; for CNC use single-flute sharp routers at high feed with vacuum hold-down — dull tools smear and melt the cells.
Can EVA Foam D60 be welded?
Yes — weldability is rated very good (70/100). Joins by contact/hot-air welding, heat lamination or hot-melt/contact adhesive (chloroprene, PU); surfaces should be scuffed or flame/plasma treated for structural bonds.
What surface finishes work on EVA Foam D60?
Seal the open cells of cut edges with heat, plasti-dip or flexible PU/latex primer before painting; flexible acrylic or PU topcoats only — rigid paints crack on flexing.
Can EVA Foam D60 be formed, bent or molded?
Compression-molded from bun stock or heat-formed at roughly 110–140 °C surface temperature; expect 2–4 % shrinkage after demold and allow for skin formation on molded faces.
What is the maximum service temperature of EVA Foam D60?
EVA Foam D60 is rated for continuous use to about 70°C (158 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in EVA Foam D60?
Yes — EVA Foam D60 is available for injection molding; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
