LCP (Liquid Crystal Polymer) vs PE 100 (HDPE Pipe Grade)
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 100 (HDPE Pipe Grade)
High-density polyethylene pipe grade with MRS (Minimum Required Strength) of 10 MPa at 20°C/50 years. The global standard material for pressurized gas and water distribution pipelines (DN 20 to DN 2000). Bimodal molecular weight distribution provides excellent ESCR (Environmental Stress Crack Resistance), slow crack growth resistance and impact strength. SDR ratings from 7.4 to 26. Fusion-weldable (butt, electro, socket). Operating temperature -40°C to +60°C. Compliant with ISO 4427 (water) and ISO 4437 (gas).
