GPO-3 is a thermoset polyester sheet material with glass reinforcement. GPO-3 is resilient to impacts, robust, stiff, and dimensionally stable. Exceptional electrical characteristics of the material include flame, arc, and track resistance. It is frequently utilised for electrical insulating purposes. Additionally, GPO-3 is employed in mechanical applications that need it to be strong, rigid, dimensionally stable, and reasonably priced.
1. Our Production
2. Product Description
A glass reinforced thermoset polyester with good electrical characteristics in ark and track resistance is GPO3 polyester glass laminate. It is suitable for a wide range of applications in the mechanical and electro-mechanical fields thanks to its exceptional strength, dimensional stability, and stiffness. The substance is flame-resistant since it complies with Nema GPO3 specifications.
Due to its great rigidity and stiffness, GPO3 is simple to process. It is popular for bespoke structural elements and components that need great durability and stability due to the same qualities. We have a number of internal CNC facilities, including milling, turning, sawing, and drilling tools, that enable us to transform this material.

4. Application
GPO-33 rigid lamination sheets can be machined, punched, drilled, milled, sawed, sanded, sheared, or milled and have great mechanical strength. It is also feasible to assemble using glue, metal screws, or rivets. Our sheets pass the UL94 V0 flame test, and it also works well in electrical applications needing excellent arc and carbon trace resistance in addition to flame retardancy. It has good tracking resistance and is perfect for use in pole mounts, gaskets, control panels, and other applications that call for Class F materials because of its superior mechanical and thermal qualities.
