Thermoplastic comparison
LCP (liquid crystal polymer) vs TPU (thermoplastic polyurethane)
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) | TPU (thermoplastic polyurethane) | Difference |
|---|---|---|---|
| Density | 1.4 g/cm³ | 1.2 g/cm³ | LCP (liquid crystal polymer) — 17% higher |
| Young's modulus E | 10.6 GPa | 0.03 GPa | LCP (liquid crystal polymer) — 353.3× higher |
| Tensile strength | 182 MPa | 40 MPa | LCP (liquid crystal polymer) — 4.5× higher |
Where these numbers come from
- Celanese Vectra A950 liquid crystal polymer datasheet, typical (flow-direction) values
- CAMPUS plastics database — typical grade datasheet values (campusplastics.com)
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.
