G10 Epoxy Board Green and Black Difference

G10 epoxy board, a versatile and robust material, comes in various colors, with green and black being the most common. The primary difference between green and black G10 epoxy boards lies in their composition and applications. Green G10 typically contains a higher percentage of epoxy resin, making it slightly more flexible and impact-resistant. Black G10, on the other hand, often incorporates additional materials like graphite or carbon, enhancing its strength and heat resistance. While both colors offer excellent electrical insulation properties, green G10 is frequently used in electronics and aerospace industries, whereas black G10 finds applications in high-temperature environments and heavy-duty mechanical components. The choice between green and black G10 epoxy sheets ultimately depends on the specific requirements of your project, considering factors such as thermal stability, mechanical strength, and electrical insulation needs.
