LCP (Liquid Crystal Polymer) vs PP-C (Polypropylene Copolymer)
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-C (Polypropylene Copolymer)
Polypropylene copolymer (random or block) — better impact resistance at low temperatures than PP homopolymer (PP-H). Random copolymer: excellent clarity for packaging. Block copolymer: high impact for automotive bumpers, containers, and household appliances. Trade names: Moplen (LyondellBasell), Hostalen (LyondellBasell). THE automotive interior/exterior polymer alongside ABS.
