Thermoplastic comparison
ABS vs TPU (thermoplastic polyurethane)
Every value below is a typical room-temperature figure with its source, test method and conditions — the same dataset that drives the calculators.
| Property | ABS | TPU (thermoplastic polyurethane) | Difference |
|---|---|---|---|
| Density | 1.05 g/cm³ | 1.2 g/cm³ | TPU (thermoplastic polyurethane) — 14% higher |
| Young's modulus E | 2.3 GPa | 0.03 GPa | ABS — 76.7× higher |
| Tensile strength | 44 MPa | 40 MPa | ABS — 10% higher |
| Glass transition Tg | 105 °C | -35 °C | ABS — 140 °C higher |
Where these numbers come from
- CAMPUS plastics database — typical grade datasheet values (campusplastics.com)
Typical room-temperature values for learning and preliminary design; grades vary widely and a supplier datasheet always overrides a textbook figure. Confirm against the datasheet before design work.
