|
Thick 4–6 cm midsole but still lightweight |
TPU density 0.25–0.35 g/cm³ (25–30% lighter than EVA) |
|
Energy return ≥ 80% |
Expanded TPU beads achieve 80–90% (Boost, Nitro, Helion, ZoomX) |
|
Extreme abrasion resistance |
DIN abrasion < 80 mm³ (3× better than regular EVA) |
|
Long-lasting clarity & no yellowing |
Virgin polyester-based TPU (BASF, Lubrizol, Covestro) |
|
Sustainable lines |
100% GRS-certified recycled TPU (rTPU) |

100–110°C for 3–4 hours, moisture < 0.02% |
3–4 hrs |
|
2 |
Color mixing + additives (UV, hydrolysis resistance) |
High-speed mixer |
Masterbatch 1.5–3%, additives 0.3–0.8% |
10–15 min |
|
3 |
TPU foaming (Physical or Chemical) |
Supercritical CO₂ or Azodicarbonamide machine |
180–195°C, 120–150 bar |
6–12 min |
|
4 |
Molding & cooling |
Cold mold + auto pick-up robot |
Mold temp 15–25°C, cooling 60–90 sec |
1–2 min |
|
