What is GPO-3 material? Applications of GPO-3. GPO3 laminate is a novel electrical insulation material, also known as UPGM203. It is a rigid insulating material formed by impregnating alkali-free glass fibre matt with unsaturated polyester paste, adding appropriate additives, and then hot-pressing. Hony Plastic specialises in manufacturing and supplying electrical insulation materials, including self-produced GPO3 insulating laminates. We also offer custom component machining according to client-specified drawings and dimensions. All our electrical insulation materials hold national UL certification and ROHS compliance reports, ensuring superior quality at competitive pricing.
