EPGC205/Roving Reinforced G11 is a material composed of continuous filament woven fiberglass sheets, bonded with high-temperature epoxy resin. Compared to EPGC203/G11, EPGC205/G11R utilizes roving cloth as reinforcement. This material exhibits outstanding mechanical, electrical, and physical properties, even at elevated temperatures up to 155℃.
