LCP (Liquid Crystal Polymer) vs PA6 (Nylon 6)
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.
PA6 (Nylon 6)
Polyamide 6 (Nylon 6) — the most widely used engineering thermoplastic. Excellent combination of mechanical strength, toughness, wear resistance, and chemical resistance. Properties are moisture-sensitive — conditioned (50% RH) values are significantly lower than dry values. Trade names include Ultramid B (BASF), Akulon (DSM), Zytel (DuPont). Used for gears, bearings, bushings, cable ties, structural brackets, and automotive under-hood components.
