GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PPS GF40
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.
PPS GF40
Polyphenylene Sulfide with 40% glass fiber — the ultimate under-hood engineering plastic. Service to 240°C continuous, inherently V-0 flame resistant without additives, near-zero moisture absorption (<0.02%), exceptional chemical resistance (comparable to PEEK/fluoropolymers). Trade names include Ryton R-4 (Solvay), Fortron 1140L4 (Celanese), Tedur (INEOS), TECATRON GF40 (Ensinger). Used for automotive water pump impellers, thermostat housings, EGR valves, LED reflectors, and semiconductor wafer carriers.
