In the field of electrical insulation materials, both G11 and G10 epoxy glass laminates are common decisions for engineers and designers. Both materials are known for their superior performance, but subtle differences between them can significantly impact the performance and reliability of electrical systems. In this blog post, Hangzhou Blue Sun will share a comparative analysis of G11 and G10 epoxy glass laminates for sale, highlighting their unique properties and applications.
Material Composition and Thermal Resistance
G11 and G10 laminates are both composed of woven fiberglass substrates impregnated with halogen-free epoxy resins. However, the G11 variant is engineered to withstand higher temperatures, with operating temperatures of up to 180 degrees Centigrade (Class H) compared to G10, which is typically rated for 150 degrees Centigrade (Class F). This enhanced thermal resistance makes G11 an ideal choice for applications where components are exposed to more extreme heat conditions.
Mechanical Strength and Impact Resistance
Both materials exhibit high mechanical strength, essential for withstanding the rigors of electrical systems. The G11 laminate boasts a flexural strength of ≥ 340 MPa perpendicular to laminations and a Charpy impact strength of ≥ 33 KJ/m² parallel to laminations. These properties ensure that G11 can maintain its structural integrity under stress, making it suitable for applications requiring robust mechanical support.
Electrical Insulation Properties
Electrical strength is a paramount consideration in insulation materials. G11 laminates exhibit an electric strength of ≥ 35 Kv perpendicular to laminations, providing reliable insulation even in high-voltage environments. Moreover, G11's insulation resistance of ≥ 5*(10²*10²) MΩ after immersion in water underscores its resilience in both dry and wet conditions, a critical factor for outdoor or damp applications.
Chemical and Dimensional Stability
G11 laminates are designed to resist dimensional changes, flow, and chemical attacks. With low moisture absorption, G11 maintains its performance in humid environments, ensuring long-term reliability. This chemical stability is crucial for applications where the laminate may be exposed to various chemicals or aggressive environments.
Combustibility and Safety
Safety is a non-negotiable aspect in material selection. G11 laminates have a combustibility level of 94-HB, indicating a low flame spread rate. This characteristic is vital for applications where fire safety is a priority, such as in electrical enclosures and control panels.
Conclusion
The choice between G11 and G10 epoxy glass laminates hinges on the specific requirements of the application. While both materials offer excellent mechanical strength and electrical insulation properties, G11's superior thermal resistance, impact strength, and chemical stability make it the preferred option for high-temperature and chemically aggressive environments. Engineers and designers must carefully consider these factors to ensure the optimal performance and longevity of their electrical systems.
The choice between G11 and G10 epoxy glass laminates depends on the specific requirements of the application. Both materials offer excellent mechanical strength and electrical insulation properties. Engineers and designers need to carefully consider these factors to ensure optimal performance and longevity of their electrical systems.
