Thermoplastic comparison
Polycarbonate (PC) 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 | Polycarbonate (PC) | PVDF (polyvinylidene fluoride) | Difference |
|---|---|---|---|
| Density | 1.2 g/cm³ | 1.78 g/cm³ | PVDF (polyvinylidene fluoride) — 48% higher |
| Young's modulus E | 2.4 GPa | 2 GPa | Polycarbonate (PC) — 20% higher |
| Tensile strength | 65 MPa | 45 MPa | Polycarbonate (PC) — 44% higher |
| Glass transition Tg | 147 °C | -35 °C | Polycarbonate (PC) — 182 °C higher |
Where these numbers come from
- Callister & Rethwisch, Materials Science and Engineering, 10th ed.
- 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.
