LCP (Liquid Crystal Polymer) vs PEEK CF30
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 CF30
PEEK with 30% short carbon fiber — the stiffest and strongest injection-moldable thermoplastic compound available. E-Mod ~24 GPa (vs 11 GPa GF30, 4.1 unfilled). UTS ~212 MPa. Electrically conductive (antistatic/EMI shielding). Outstanding wear/friction properties. Trade names: Victrex 450CA30, TECAPEEK CF30 (Ensinger), KetaSpire CF30 (Solvay). Used for semiconductor wafer handling, bearing cages, compressor components, and metal-replacement structural parts.
