Thermoplastic comparison
LCP (liquid crystal polymer) vs PHB (polyhydroxybutyrate, a PHA)
Every value below is a typical room-temperature figure with its source, test method and conditions — the same dataset that drives the calculators.
| Property | LCP (liquid crystal polymer) | PHB (polyhydroxybutyrate, a PHA) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 1.25 g/cm³ | LCP (liquid crystal polymer) — 12% higher |
| Young's modulus E | 10.6 GPa | 3.5 GPa | LCP (liquid crystal polymer) — 3.0× higher |
| Tensile strength | 182 MPa | 40 MPa | LCP (liquid crystal polymer) — 4.5× higher |
| Melting point Tm | 280 °C | 177 °C | LCP (liquid crystal polymer) — 103 °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.
