| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
Ultra-soft low-density foam | Pick for insoles, slippers and comfort cushioning layers where Asker C 38–45 gives the lightest, softest feel; support is poor and the foam collapses under sustained load. | — | 1 | 220 | 28 Shore A |
RECThis page Recycled-content EVA foam | Use to cut cost and carbon footprint with 10–30 % factory-offcut regrind, accepting less uniform cell structure, lower rebound at 1.6 MPa and harder colour-consistency control. | — | 2 | 190 | 13 Shore D |
Soft midsole foam | Choose the soft Asker C 45–52 sheet for running-shoe midsole cushioning with good rebound and underfoot feel; durability is only moderate at 0.15 g/cm³. | — | 2 | 260 | 10 Shore D |
Flame-retardant EVA foam sheet | Specify for safety footwear, rail transit parts and packaging liners using halogen-free ATH/MDH plus intumescent or brominated systems; density rises to 0.28 g/cm³ while strength falls to 1.8 MPa. | — | 2 | 150 | 18 Shore D |
C55Default Standard footwear midsole sheet | Use as the general-purpose midsole and buffing-board sheet at Asker C 52–58, balancing cushioning, support and durability with good secondary compression-moulding behaviour. | — | 2 | 250 | 12 Shore D |
Hot rolled | Choose for mid- to high-end running midsoles needing high rebound and collapse resistance: POE/OBC modification or supercritical N₂/CO₂ physical foaming gives 0.16 g/cm³ at higher cost. | — | 2 | 300 | 9 Shore D |
Phylon | Choose for athletic midsoles needing a dense skin and tight dimensional accuracy: cut blanks are compression-moulded and secondary-foamed, giving 0.22 g/cm³, 2.6 MPa and low finished weight. | — | 3 | 230 | 15 Shore D |
Injection Phylon | Use when throughput matters and skiving scrap must be eliminated: the foam is injection-moulded directly to shape, trading a higher 0.25 g/cm³ density plus poorer surface texture and rebound. | — | 3 | 210 | 17 Shore D |
Firm high-density foam | Pick for stability blocks, support bars, safety-shoe midsoles and outsole pads where Asker C 60–70 gives stiff, wear-resistant support; cushioning drops and weight rises to 0.26 g/cm³. | — | 3 | 200 | 52 Shore A |
EVA/rubber blend foam | Pick for one-piece midsole/outsole units and slipper soles: SBR/BR or reclaimed rubber raises abrasion and tear resistance to 3.5 MPa, at 0.32 g/cm³ and higher hardness and weight. | — | 4 | 250 | 20 Shore D |

Working with EVA Foam Sheet (Footwear Grade) REC
Is EVA Foam Sheet (Footwear Grade) easy to machine?
Blade skiving, hydraulic die cutting, waterjet and CNC milling are all straightforward. Use sharp thin edges with adequate cooling to avoid friction-melted edges and compression distortion.
Can EVA Foam Sheet (Footwear Grade) be welded?
Hot-plate, hot-air or high-frequency welding is possible when polar additives are present, but production joints are normally neoprene or PU adhesive. Prime with UV, plasma or chemical treatment to raise surface energy before bonding.
Can EVA Foam Sheet (Footwear Grade) be formed, bent or molded?
Primary crosslinked compression foaming runs at 160-180 C, followed by skiving after cooling. Secondary hot pressing (Phylon) sets shape at about 150-170 C with a 2-5 % shrinkage allowance; injection foaming uses melt temperatures of about 120-150 C.
What surface finishes work on EVA Foam Sheet (Footwear Grade)?
Can be sanded, flame or wheel trimmed, screen printed, water-transfer printed and heat-transfer decorated. Opened surface cells pick up dirt, so exposed faces are usually painted or laminated with rubber or TPU sheet for wear resistance.
