Thermoplastic comparison
LCP (liquid crystal polymer) vs Acrylic (PMMA)
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) | Acrylic (PMMA) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 1.19 g/cm³ | LCP (liquid crystal polymer) — 18% higher |
| Young's modulus E | 10.6 GPa | 3.1 GPa | LCP (liquid crystal polymer) — 3.4× higher |
| Tensile strength | 182 MPa | 72 MPa | LCP (liquid crystal polymer) — 2.5× 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.
