LCP (Liquid Crystal Polymer) vs PP-H (Polypropylene Homopolymer)
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-H (Polypropylene Homopolymer)
Polypropylene Homopolymer — the lightest common engineering plastic (0.905 g/cm³). Excellent chemical resistance (esp. to acids and bases), good fatigue resistance (integral living hinges), and low moisture absorption. Becomes brittle below 0°C. Used for chemical tanks, HVAC ducts, pump housings, food containers, automotive battery cases, and medical lab equipment.
