NEMA GPO-1
Product Definition:
Glass Matte Laminates GPO-1 is a type of thermoset composite material that is commonly used for electrical insulation applications. It is made from layers of glass cloth impregnated with a polyester resin and bonded together using heat and pressure.
The material has a matte finish and is typically light gray in color. It is known for its excellent electrical insulation properties, high mechanical strength, and good dimensional stability. These properties make it suitable for use in a variety of applications such as switchgear, busbars, and electrical cabinets.
Glass Matte Laminates GPO-1 is available in a range of thicknesses, from 0.25mm to 50mm, and can be supplied in sheets or rolls. It is also easy to machine and can be drilled, sawed, or milled to create complex shapes and parts.
The material meets the standards of UL 94V-0 for flammability and has a maximum continuous operating temperature of 130°C. It also has excellent resistance to moisture, chemicals, and UV radiation.
Overall, Glass Matte Laminates GPO-1 is a high-performance material that is ideal for use in electrical applications where high electrical insulation and mechanical strength are required.
