GPO-3 is a glass reinforced thermoset polyester sheet material. GPO-3 is strong, stiff, dimensionally stable, and impact resistant. The material also has excellent electrical properties including flame, arc, and track resistance. It is widely used for electrical insulating applications. GPO-3 is also used for mechanical applications where strength, stiffness, dimensional stability, and relatively low cost are required.
It is typically used in phase and end barriers, insulation support, bus bar support, mounting panels, transformers, antenna bases, and spacers.
