Product Description
What is GPO-3 material?
GPO3 polyester glass laminate is a glass fiber reinforced thermosetting polyester electrical grade sheet. This composite has application temperatures up to 155°C and offers an excellent combination of high strength and low smoke generation. The material meets the specification requirements of Nema GPO3 and is flame retardant. Due to its extreme strength, dimensional stability and rigidity, GPO3 is easy to process, making it suitable for many applications in the mechanical and electromechanical industries.
