LCP (Liquid Crystal Polymer) vs TPU (Thermoplastic Polyurethane)
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.
TPU (Thermoplastic Polyurethane)
Thermoplastic polyurethane elastomer — bridges the gap between rubber and rigid plastics. Exceptional abrasion resistance, high elongation (300-700%), and good oil/grease resistance. Available in wide hardness range (60 Shore A to 74 Shore D). Ester-based: better oil resistance. Ether-based: better hydrolysis/microbial resistance. Major trade names: Elastollan (BASF), Desmopan/Texin (Covestro), Estane (Lubrizol). Used for seals, hoses, cable jackets, shoe soles, phone cases, wheels/rollers, and 3D printing filament.
