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.

Differences Between Garolite Sheet and G10 Sheet

Garolite sheet and G10 sheet are both high-performance composite materials used in various industrial applications. However, they have distinct characteristics that set them apart. Garolite, also known as phenolic sheet, is made from layers of paper or fabric impregnated with phenolic resin. On the other hand, G10 sheet, a type of G10 epoxy sheet, is composed of woven glass fabric layers bonded with epoxy resin. The primary differences lie in their composition, mechanical properties, and electrical insulation capabilities. G10 sheet generally offers superior strength, impact resistance, and dimensional stability compared to Garolite. It also exhibits better electrical insulation properties, making it ideal for high-voltage applications. Garolite, while less robust, is more cost-effective and easier to machine, suitable for applications where extreme mechanical stress is not a concern.
