LCP (Liquid Crystal Polymer) vs PTFE (Teflon)
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.
PTFE (Teflon)
Polytetrafluoroethylene — the most chemically resistant polymer. Lowest friction coefficient of any solid material (~0.05-0.10). Service range -240°C to +260°C continuous. Cannot be melt-processed — must be sintered from powder (like ceramics). Very low mechanical strength. Trade name Teflon (Chemours/DuPont). Used for seals, gaskets, bearings, non-stick coatings, chemical reactor linings, electrical insulation, and lab equipment.
