Thermoplastic comparison
Polyamide 12 (PA12, Nylon 12) 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 | Polyamide 12 (PA12, Nylon 12) | PTFE (Teflon) | Difference |
|---|---|---|---|
| Density | 1.01 g/cm³ | 2.17 g/cm³ | PTFE (Teflon) — 2.1× higher |
| Young's modulus E | 1.4 GPa | 0.5 GPa | Polyamide 12 (PA12, Nylon 12) — 2.8× higher |
| Tensile strength | 50 MPa | 24 MPa | Polyamide 12 (PA12, Nylon 12) — 2.1× higher |
| Melting point Tm | 178 °C | 327 °C | PTFE (Teflon) — 149 °C higher |

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.
