Thermoplastic comparison
PVC, plasticized (flexible, PVC-P) vs PVDF (polyvinylidene fluoride)
Every value below is a typical room-temperature figure with its source, test method and conditions — the same dataset that drives the calculators.
| Property | PVC, plasticized (flexible, PVC-P) | PVDF (polyvinylidene fluoride) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 1.78 g/cm³ | PVDF (polyvinylidene fluoride) — 27% higher |
| Young's modulus E | 1.4 GPa | 2 GPa | PVDF (polyvinylidene fluoride) — 43% higher |
| Tensile strength | 16 MPa | 45 MPa | PVDF (polyvinylidene fluoride) — 2.8× higher |
| Glass transition Tg | 75 °C | -35 °C | PVC, plasticized (flexible, PVC-P) — 110 °C higher |

- MakeItFrom.com materials database — typical grade values
- 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.
