FR-4 (Glass Epoxy Laminate) vs PE 100 (HDPE Pipe Grade)
Side-by-side chemical composition and mechanical property comparison.
Overview
FR-4 (Glass Epoxy Laminate)
Flame retardant woven fiberglass cloth with epoxy resin binder — the worldwide standard substrate material for printed circuit boards (PCBs). Designated NEMA grade FR-4 and IPC-4101. Good mechanical strength, dimensional stability and electrical insulation up to 130°C (Tg). Dielectric constant 4.2–4.7 at 1 MHz. Self-extinguishing (UL94 V-0). Used for single/multilayer PCBs, electrical insulation boards, structural composites in electronics, test fixtures and jigs. Available in thicknesses 0.1–50 mm.
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).
