Thermoplastic comparison
PETG (glycol-modified PET) 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 | PETG (glycol-modified PET) | PVC, plasticized (flexible, PVC-P) | Difference |
|---|---|---|---|
| Density | 1.3 g/cm³ | 1.4 g/cm³ | PVC, plasticized (flexible, PVC-P) — 8% higher |
| Young's modulus E | 2.2 GPa | 1.4 GPa | PETG (glycol-modified PET) — 57% higher |
| Tensile strength | 53 MPa | 16 MPa | PETG (glycol-modified PET) — 3.3× higher |
| Glass transition Tg | 81 °C | 75 °C | PETG (glycol-modified PET) — 6 °C higher |

- 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.
