LCP (Liquid Crystal Polymer) vs PE-LD (Low-Density Polyethylene)
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.
PE-LD (Low-Density Polyethylene)
Low-density polyethylene — branched chain structure gives flexibility, transparency, and easy processing. THE film/packaging polymer: cling wrap, carrier bags, squeeze bottles, shrink wrap. Also used for cable insulation, agricultural film, and coatings. Lower density (0.91-0.93) and strength than PE-HD but much more flexible.
