1. Why TPU Is the Irreplaceable Material for 2025 Chunky Sneakers
|
2025 Chunky Sneaker Requirements |
How Premium TPU Delivers |
|
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) |
2. 5-Step Production Process for Chunky TPU Midsoles – Energy Return > 85% (OEM Standard for Europe)

Detailed Process |
Required Equipment |
JM Recommended Parameters |
Cycle Time |
|
1 |
Drying TPU pellets |
Vacuum or hot-air dryer |
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 |
|
5 |
Finishing (trimming & outsole bonding) |
CNC trimming + PUR hot-melt glue line |
Bonding strength > 7 N/mm (SATRA standard) |
5–8 min |
→ Shrinkage only 0.8–1.2% → Real energy return 82–90% (tested on SATRA Flexometer) → Abrasion resistance < 70 mm³ (DIN 53516)
