Thermoplastic comparison
Polycarbonate (PC) vs Polypropylene (PP)
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) | Polypropylene (PP) | Difference |
|---|---|---|---|
| Density | 1.2 g/cm³ | 0.905 g/cm³ | Polycarbonate (PC) — 33% higher |
| Young's modulus E | 2.4 GPa | 1.4 GPa | Polycarbonate (PC) — 71% higher |
| Tensile strength | 65 MPa | 34 MPa | Polycarbonate (PC) — 91% higher |
| Glass transition Tg | 147 °C | -10 °C | Polycarbonate (PC) — 157 °C higher |

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.
