Grade · open for datasheet	Best for	Tensile MPa	Elong. %	Hardness
C40 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
REC 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
C50 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
FR 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
HR 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
PHY 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
IP 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
C65 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-RB 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

What is EVA Foam Sheet (Footwear Grade)?

EVA Foam Sheet (Footwear Grade) is a closed-cell ethylene-vinyl acetate foam produced to the footwear standards QB/T 2199 and QB/T 2200 and tested to ASTM D3575, molded or skived for midsoles and insoles. It balances cushioning, resilience and low density: the 0.18 g/cm3 reference grade gives 2 MPa tensile strength, 250 % elongation and a machinability score of 85. Maximum service temperature is about 65 C, and the foam compression-sets and shrinks after secondary pressing, so allow for it in tooling. Use crosslinked PE or TPO foam where higher temperature capability is required. EVA Foam Sheet (Footwear Grade) has a density of 0.18 g/cm³ (0.0065 lb/in³), lighter than 85% of polymer grades. Its glass-transition temperature is -30°C (-22 °F). EVA Foam Sheet (Footwear Grade) has a tensile strength of 2 MPa (0.29 ksi), weaker than 84% of polymer grades. Elongation at break is 250% and the elastic modulus is 0.01 GPa (0.0012 Msi).

Working with EVA Foam Sheet (Footwear Grade)

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.
