ETPEE foam molding
// Elastic from −40°C up to at least 120°C without decay, high tear strength, excellent abrasion resistance, and up to 20% lighter than EVA. Where a soft part also has to survive heat, chemicals and repeated load, this is the elastomer that does not tap out first.
The figures on this page are published industry and supplier values for this material family, not measured DBM product data — we do not have our own grade-level test results for ETPEE yet. They are accurate enough to size a part and to rule options in or out. Final numbers are confirmed by us in writing against your part before you commit to anything.
| Property | Value | Source |
|---|---|---|
| Foam density | 100–160 kg/m³ — up to 20% lighter than EVA | ✅ |
| Hardness | 30–45 Shore C, about 10 points harder than foamed TPU; Asker-C 42 measured | ✅ |
| Service temperature | −40 to 120°C with no loss of elasticity. Public sources report up to 150°C and flexibility at −70°C; we quote the conservative figure until our own testing settles it | ⚠️ |
| Tear and abrasion | High tear strength, excellent abrasion resistance | ✅ |
| Base polymer density | 1.16 g/cm³ unfoamed solid | 📊 |
| Expansion ratio | 1.80–25.01, within a foaming window of roughly 30°C | 📊 |
| Recovery | A micro-crosslinked network raises the elastic modulus; excellent self-recovery | 📊 |
| Shrinkage control | 8% at high hard-segment content, over 50% at low — the key to forming stability | 📊 |
| Foaming route | Supercritical CO₂ / N₂ | ✅ |
| Compression / tensile / conductivity / water absorption / flame | No public figure — we request it with your enquiry | ⬜ |

Heavy-duty industrial damping
Soft where it counts, tough everywhere else.
Extreme-environment protection
The widest usable temperature span of any soft foam here.
Why we can run it
// A foaming window of roughly 30°C, and shrinkage swinging from 8% to over 50% with hard-segment content — precise steam control is not optional for this material.
