Thermoplastic comparison
LCP (liquid crystal polymer) vs UHMW-PE (ultra-high-molecular-weight polyethylene)
Every value below is a typical room-temperature figure with its source, test method and conditions — the same dataset that drives the calculators.

Where these numbers come from
- Celanese Vectra A950 liquid crystal polymer datasheet, typical (flow-direction) values
- MakeItFrom.com materials database — typical grade 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.
