GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PE-LLD (Linear Low-Density Polyethylene)
Side-by-side chemical composition and mechanical property comparison.
Overview
GFRP / GFK (Glass Fiber Reinforced Epoxy)
Glass fiber reinforced epoxy composite — the cost-effective structural composite for industrial, marine and construction applications. E-glass fiber in epoxy matrix. Unidirectional: UTS ~1000 MPa, E ~40 GPa. Quasi-isotropic layup: UTS ~300 MPa, E ~18 GPa. Density 1.8–2.1 g/cm³. Electrically insulating (unlike CFRP). Used for boat hulls, wind turbine blades, chemical tanks/pipes, architectural panels, ladders, gratings, automotive body panels and electrical insulation structures.
PE-LLD (Linear Low-Density Polyethylene)
Linear low-density polyethylene — short-chain branching via copolymerization with alpha-olefins (butene, hexene, octene). Better puncture resistance, tear strength, and seal strength than PE-LD at same density. THE modern stretch wrap and food packaging film. Also used for agricultural film, liners, bags, and blown film. Largely replacing PE-LD in film applications.
