A flexible elastomer with high elastic rebound and low energy loss, so it returns energy sharply when it flexes. It stays flexible in the cold and resists fatigue under repeated loading. It resists oils and greases, though some solvents attack the polyether phase.

Mechanical
| Shore hardness | 90AISO 868 |
| Tensile strength | 36 MPa |
| Elongation at break | >1000% (datasheet); >500% is the conservative printed-part expectation |
Physical
| Density | 1.00 g/cm³ — the lightest flexible we run |
Service behavior
| Cold flexibility | Retains flexibility to −60 °C. |
| Rebound | High energy return, low compression set — the athletic elastomer. |
| Chemical | Resists fuels and oils. |
