LCP (Liquid Crystal Polymer) vs PP GF30
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.
PP GF30
Polypropylene with 30% short glass fiber — a cost-effective alternative to PA GF30 for applications up to ~130°C. Much cheaper base resin (PP vs PA), zero moisture sensitivity, and excellent chemical resistance. Lower strength than PA6 GF30 (UTS 80 vs 175 MPa) but sufficient for many structural parts. Trade names include Celstran PP-GF30 (Celanese), Tepex (LANXESS), Stamax (SABIC). Used for automotive front-end carriers, battery trays, HVAC components, and household appliance frames.
