Working with POE Foam

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.

POE Foam chemical composition (wt %)

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 — frequently asked

What is POE Foam used for?

POE Foam is typically used for performance running shoe midsoles, sports cushioning inserts, premium packaging cushioning and vibration damping pads. In short: higher rebound than EVA; low-density footwear foam; surface treatment needed for bonding.

What is the tensile strength of POE Foam?

POE Foam has a typical tensile strength of 2 MPa (0.261 ksi) — weaker than 85% of polymer grades. Strength varies by condition: see the 8 listed tempers.

Is POE Foam easy to machine?

Reasonably — machinability is rated good (60/100, better than 51% 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 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?

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.

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 is the maximum service temperature of POE Foam?

POE Foam 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.

How much does POE Foam cost?
