GPO3 polyester glass laminate is a glass-reinforced thermoset polyester known for its outstanding electrical resistance to arcing and tracking. Its exceptional strength, rigidity, and dimensional stability make it ideal for diverse mechanical and electro-mechanical uses. This material complies with the NEMA GPO3 standard, ensuring flame-retardant properties.
Thanks to its high stiffness and rigidity, GPO3 is straightforward to machine. These qualities also make it a preferred choice for custom structural components requiring long-lasting durability and stability. Our in-house CNC machining capabilities include milling, turning, sawing, and drilling, enabling precise fabrication.
