Thermoplastic comparison
PTFE (Teflon) 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 | PTFE (Teflon) | TPU (thermoplastic polyurethane) | Difference |
|---|---|---|---|
| Density | 2.17 g/cm³ | 1.2 g/cm³ | PTFE (Teflon) — 81% higher |
| Young's modulus E | 0.5 GPa | 0.03 GPa | PTFE (Teflon) — 16.7× higher |
| Tensile strength | 24 MPa | 40 MPa | TPU (thermoplastic polyurethane) — 67% higher |
Where these numbers come from
- Callister & Rethwisch, Materials Science and Engineering, 10th ed.
- 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.
