Thermoplastic comparison
ABS vs PTFE (Teflon)
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 | PTFE (Teflon) | Difference |
|---|---|---|---|
| Density | 1.05 g/cm³ | 2.17 g/cm³ | PTFE (Teflon) — 2.1× higher |
| Young's modulus E | 2.3 GPa | 0.5 GPa | ABS — 4.6× higher |
| Tensile strength | 44 MPa | 24 MPa | ABS — 83% higher |

- CAMPUS plastics database — typical grade datasheet values (campusplastics.com)
- Callister & Rethwisch, Materials Science and Engineering, 10th ed.
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.
