MFGC201(G5, G9) Melamine Glass Cloth Laminated Sheet is made from alkali-free E-glass cloth impregnated with melamine resin and processed under high heat and pressure. This material offers excellent flame resistance, arc resistance, and flame retardant properties, making it suitable for both mechanical and electrical applications.
It is commonly used in transformers, electric motors, cabinets, control boxes, switches, household appliances, railway systems, automobiles, computers, and medical devices.
With high mechanical strength and reliable electrical insulation, MFGC201 is ideal for structural components in electrical equipment requiring high arc resistance and durability.
