Thermoplastic comparison
LCP (liquid crystal polymer) vs PTFE (Teflon)
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) | PTFE (Teflon) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 2.17 g/cm³ | PTFE (Teflon) — 55% higher |
| Young's modulus E | 10.6 GPa | 0.5 GPa | LCP (liquid crystal polymer) — 21.2× higher |
| Tensile strength | 182 MPa | 24 MPa | LCP (liquid crystal polymer) — 7.6× higher |
| Melting point Tm | 280 °C | 327 °C | PTFE (Teflon) — 47 °C higher |
Where these numbers come from
- Celanese Vectra A950 liquid crystal polymer datasheet, typical (flow-direction) values
- Callister & Rethwisch, Materials Science and Engineering, 10th ed.
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.
