| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
Ultra-low-density supercritical POE foam, 0.08–0.11 g/cm³ | Pick when minimum weight matters (racing midsoles, lightweight padding); softer and less durable. | — | 1 | 200 | 25 Shore A |
Expanded POE bead foam, steam-chest molded | Choose for complex 3-D near-net shapes and the highest energy return (E-TPU-like bead structure) with tunable local density. | — | 2 | 180 | 33 Shore A |
Antistatic / carbon-loaded conductive POE foam | For electronics packaging and cleanroom cushioning where static dissipation is required. | — | 2 | 150 | 45 Shore A |

Working with POE Foam SCF-D22
Is POE Foam easy to machine?
Die-cut, water-jet, skive or CNC hot-wire; use sharp steel rule dies and light spray lubricant — routers smear the soft skin and buffing wheels load quickly.
Can POE Foam be welded?
Hot-air/hot-plate and impulse welding work on the skin; the non-polar surface is not RF weldable, so corona, plasma or UV-primer treatment is required before PU/water-based adhesive bonding.
Can POE Foam be formed, bent or molded?
Compression-mold at 160–175 °C then cold-set for XL-POE, steam-chest mold at 110–135 °C for bead foam, or extrude/inject with supercritical CO₂/N₂ (MuCell-type) at 150–200 °C melt; expect 1.5–5 % post-mold shrinkage over 24–48 h and design tooling oversize.
What surface finishes work on POE Foam?
Buff and wash before cementing; water-based PU primer plus corona treatment is standard for sole bonding. Foam takes solvent inks and pad printing poorly — use in-mold color masterbatch or foam-compatible screen inks.

POE Foam SCF-D22 has a typical tensile strength of 3 MPa (0.406 ksi) — weaker than 83% of polymer grades. Strength varies by condition: see the 8 listed tempers.
Is POE Foam SCF-D22 easy to machine?
Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Die-cut, water-jet, skive or CNC hot-wire; use sharp steel rule dies and light spray lubricant — routers smear the soft skin and buffing wheels load quickly.
Can POE Foam SCF-D22 be welded?
Yes — weldability is rated good (55/100). Hot-air/hot-plate and impulse welding work on the skin; the non-polar surface is not RF weldable, so corona, plasma or UV-primer treatment is required before PU/water-based adhesive bonding.
What surface finishes work on POE Foam SCF-D22?

What is the maximum service temperature of POE Foam SCF-D22?
POE Foam SCF-D22 is rated for continuous use to about 65°C (149 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
