ETPEE is expanded thermoplastic polyester elastomer (TPEE), a bead foam steam-molded within a very narrow window. Elastic from −40°C up to at least 120°C without decay, 55% rebound, high tear strength and excellent abrasion resistance. Where a soft part also has to survive heat, chemicals and repeated load, this is the elastomer that does not tap out first.

| Property | Value |
|---|---|
| Foam density | 100–150 kg/m³ |
| Hardness | Asker-C 42 |
| Service temperature | −40 to 120°C with no loss of elasticity |
| Tear and abrasion | High tear strength, excellent abrasion resistance |

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 heat-resistant elastomer with a very narrow molding window. DBM molds it.
