Thermoplastic comparison
LCP (liquid crystal polymer) vs PETG (glycol-modified PET)
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) | PETG (glycol-modified PET) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 1.3 g/cm³ | LCP (liquid crystal polymer) — 8% higher |
| Young's modulus E | 10.6 GPa | 2.2 GPa | LCP (liquid crystal polymer) — 4.8× higher |
| Tensile strength | 182 MPa | 53 MPa | LCP (liquid crystal polymer) — 3.4× higher |
Where these numbers come from
- Celanese Vectra A950 liquid crystal polymer datasheet, typical (flow-direction) values
- MakeItFrom.com materials database — typical grade values
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.
