Thermoplastic comparison
Polyamide 6 (PA6, Nylon 6) 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 6 (PA6, Nylon 6) | PTFE (Teflon) | Difference |
|---|---|---|---|
| Density | 1.13 g/cm³ | 2.17 g/cm³ | PTFE (Teflon) — 92% higher |
| Young's modulus E | 2.8 GPa | 0.5 GPa | Polyamide 6 (PA6, Nylon 6) — 5.6× higher |
| Tensile strength | 78 MPa | 24 MPa | Polyamide 6 (PA6, Nylon 6) — 3.3× higher |
| Melting point Tm | 220 °C | 327 °C | PTFE (Teflon) — 107 °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.
