Thermoplastic comparison
ABS vs Polyamide 12 (PA12, Nylon 12)
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 | Polyamide 12 (PA12, Nylon 12) | Difference |
|---|---|---|---|
| Density | 1.05 g/cm³ | 1.01 g/cm³ | ABS — 4% higher |
| Young's modulus E | 2.3 GPa | 1.4 GPa | ABS — 64% higher |
| Tensile strength | 44 MPa | 50 MPa | Polyamide 12 (PA12, Nylon 12) — 14% higher |
| Glass transition Tg | 105 °C | 45 °C | ABS — 60 °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.
