Thermoplastic comparison
ABS vs PVC, plasticized (flexible, PVC-P)
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 | PVC, plasticized (flexible, PVC-P) | Difference |
|---|---|---|---|
| Density | 1.05 g/cm³ | 1.4 g/cm³ | PVC, plasticized (flexible, PVC-P) — 33% higher |
| Young's modulus E | 2.3 GPa | 1.4 GPa | ABS — 64% higher |
| Tensile strength | 44 MPa | 16 MPa | ABS — 2.8× higher |
| Glass transition Tg | 105 °C | 75 °C | ABS — 30 °C higher |

- CAMPUS plastics database — typical grade datasheet values (campusplastics.com)
- MakeItFrom.com materials database — typical grade values
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.
