LCP (Liquid Crystal Polymer) vs PEEK 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.
PEEK GF30
PEEK with 30% short glass fiber reinforcement. Dramatically increased stiffness (E-Mod 11 GPa vs 4.1 unfilled) and strength (UTS 160 vs 100 MPa) with reduced elongation and creep. Maintains PEEK's chemical resistance and high-temp capability (continuous 250°C). Trade names: Victrex 450GL30, TECAPEEK GF30 (Ensinger), KetaSpire GF30 (Solvay). Used for structural brackets, pump housings, valve seats, bearing cages, and semiconductor wafer handling where higher stiffness than unfilled PEEK is needed.
