GPO-3 is a mineral filled, continuous fiberglass reinforced thermoset unsaturated polyester material. Its high strength, GPO-3 a flame resistance, and low smoke generation make GPO-3 the industry standard for flame and arc resistant electrical insulation, and it is used frequently in the transportation industry – where smoke generation and toxicity are a prime concern. GPO-3 is a good choice for use in switch gears and control panels.
