Black G10 Epoxy Sheet (G10/EPGC201) is a high-performance laminated electrical insulation material manufactured by impregnating alkali-free woven fiberglass cloth with epoxy resin, followed by drying, hot pressing, and curing. It features high density, low water absorption, excellent dimensional stability, outstanding mechanical strength, and reliable electrical insulation properties.
The addition of black pigment provides a uniform black appearance and low light transmission, making it suitable for applications where appearance, wear resistance, and electrical insulation are equally important. It is widely used in electronics, industrial machinery, automotive manufacturing, aerospace, and precision engineering.
Black G10 offers exceptional tensile, compressive, and flexural strength, allowing it to withstand heavy mechanical loads and impact without deformation.
With high dielectric strength and stable insulation performance, G10 is widely used for electrical insulation components operating under high-voltage conditions.
The material exhibits excellent resistance to acids, alkalis, oils, solvents, and many industrial chemicals, making it suitable for harsh working environments.
Black G10 maintains excellent mechanical and electrical performance under elevated temperatures and is suitable for continuous industrial applications.
Its extremely low moisture absorption ensures dimensional stability and consistent insulation performance even in humid environments.
G10 can be easily machined by CNC routing, drilling, milling, turning, laser cutting, and waterjet cutting, allowing complex custom parts to be manufactured with high precision.
Black G10 is widely used for:
Its excellent insulation performance and mechanical strength ensure long-term reliability of electrical equipment.
Due to its lightweight construction and high strength, Black G10 is used in:
It helps reduce overall aircraft weight while maintaining structural integrity.
In industrial machinery, Black G10 is commonly manufactured into:
Its excellent wear resistance and chemical stability significantly improve equipment service life.
