Glass Polyester (GPO-1, GPO-2,GPO-3)
Glass Polyester is a Glass-Mat Reinforced Polyester. GPO-1 is a cost-effective, general purpose laminate. It is a solid choice for applications in which good electrical properties, good physical strength and moderate heat resistance are required.
GPO-2 is the laminate of choice when arc or flame resistance is required. It has good electrical and physical properties and heat resistance.
GPO-3 is the laminate to choose when arc, flame and carbon track-resistance are needed. GPO-3 offers good physical strength and moderate heat resistance. It is used extensively in the making of electrical components.
