LCP (Liquid Crystal Polymer) vs PBT 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.
PBT GF30
Polybutylene Terephthalate with 30% glass fiber — THE connector and electrical component material. Key advantage over PA6 GF30: near-zero moisture absorption (0.02-0.2%), so mechanical and electrical properties are stable regardless of humidity. Lower UTS than PA6 GF30 but consistent. Trade names include Ultradur B4300 G6 (BASF), Valox 420 (SABIC), Celanex (Celanese), Crastin (DuPont). Used for electrical connectors, relay housings, coil formers, automotive sensors, and any part requiring dimensional stability in humid environments.
