Arc-Resistant GPO3 Fiberglass Sheets and Strips

Often used for electrical applications in humid environments, these GPO3 fiberglass sheets and strips are arc and track resistant. They offer better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.
