LCP (Liquid Crystal Polymer) vs PE-UHMW
Side-by-side chemical composition and mechanical property comparison.
Overview
LCP (Liquid Crystal Polymer)
Liquid Crystal Polymer — self-reinforcing aromatic polyester with outstanding flow into thin walls (<0.2mm). Extremely low moisture absorption (0.02%), minimal warpage, excellent dimensional stability. Near-zero creep. Inherently flame-retardant (V-0 at 0.2mm). Very high HDT (>270°C). Trade names: Vectra (Celanese), Zenite (DuPont), Siveras (Toray). THE micro-connector and SMT-reflow-compatible polymer. Used for SMD connectors, fiber optic ferrules, chip carriers, sensors, and ultra-thin-wall electronic housings.
PE-UHMW
Ultra-High Molecular Weight Polyethylene — the highest impact-strength thermoplastic. Molecular weight 2-6 million g/mol. Self-lubricating, extremely wear-resistant (15x better than carbon steel), and chemically inert. Used for hip/knee implant bearings, conveyor guides, dock fenders, chute liners, food processing equipment, and ballistic armor (Dyneema/Spectra fiber form).
