What is the difference between g10 and g11 in epoxy sheet?

Jun 11, 2025

1, G11 Material Overview
G11 material is a high-performance epoxy composite material composed of high-quality epoxy resin and curing agent. It has the characteristics of high purity, excellent mechanical properties, good weather resistance and corrosion resistance, and is widely used in fields such as power equipment, aerospace, electronic communication, etc. Specifically, G11 epoxy composite material achieves high density, high strength, and excellent insulation performance through specific manufacturing processes, becoming an indispensable high-performance material in modern industry.


2, The difference between G11 and G10 materials


1. Composition difference: G11 material and G10 material have different compositions. G11 epoxy composite materials are mainly made by impregnating imported electrical grade alkali free glass fiber cloth with imported epoxy resin, and adding corresponding imported flame retardants, adhesives, and other additives through hot pressing. The G10 material is made by immersing glass cloth or glass fiber layer in epoxy resin, and then heating and compressing it. Although both use epoxy resin and glass fiber, there are differences in specific formulas and processing techniques, resulting in different performance characteristics of the final product.

 

2. Performance characteristics: Due to differences in composition, G11 and G10 also have their own strengths in performance. G11 epoxy board has the characteristics of diverse forms, easy curing, strong adhesion, low shrinkage, and excellent mechanical properties. Especially its mechanical properties, such as tensile strength, bending strength, etc., are excellent and can withstand large loads without easily breaking. In addition, G11 also has high electrical breakdown resistance and dielectric properties, which can maintain good electrical insulation in harsh environments such as high temperature and humidity. In contrast, G10 material also has higher mechanical and insulation properties, but its specific performance indicators may be slightly inferior to G11 due to differences in manufacturing processes and formulations.
 

3. Application areas: There are also certain differences between G11 material and G10 material in their application areas. Due to its excellent mechanical and electrical properties, G11 epoxy board is often used to manufacture various electrical equipment and components that require high mechanical strength and insulation performance, such as high-voltage switchgear, insulation gaskets, insulation partitions, etc. G10 material is more commonly used in applications that require high durability and waterproofness, such as the production of everyday items such as kitchen knife handles.


In summary, although both G11 material and G10 material are high-performance composite materials based on epoxy resin and glass fiber, they have certain differences in composition, performance, and application fields. The selection of suitable materials depends on specific application requirements and performance indicators. With the continuous advancement of technology and rapid development of industry, we believe that these two materials will demonstrate their unique value and potential in more fields.
