In the field of high performance materials, G11 epoxy glass laminate is a popular material for applications that require superior thermal resistance and mechanical strength. This composite material is known for its ability to withstand high temperatures while maintaining structural integrity. In this blog post, as a manufacturer, Hangzhou Blue Sun will share with you the thermal properties of G11 epoxy glass laminate.
Thermal Properties Of G11 Epoxy Glass Laminate
G11 epoxy glass laminate is crafted from a halogen-free epoxy resin combined with a woven fiberglass substrate. This unique composition endows it with remarkable properties that make it superior to its counterpart, G10. The material exhibits excellent mechanical strength at elevated temperatures and boasts good insulative properties in both wet and dry conditions. Compared to G10, G11 can endure higher temperatures, offering a slight edge in insulation capabilities.
One of the key advantages of G11 is its ability to resist dimensional changes, flow, and chemical attacks. It has a low moisture absorption rate, which is crucial for applications where the material may be exposed to humid or wet environments. This characteristic ensures that the material's performance remains consistent over time, even in challenging conditions.
The material is available in two variants to cater to different operating temperature requirements. One variant is designed for an operating temperature of 150 degrees Centigrade (Class F), while the other is rated for a higher temperature of 180 degrees Centigrade (Class H). When specifying G11 for a project, it is crucial to ensure that the chosen grade is suitable for the intended operating environment.
Technical specifications of G11 epoxy glass laminate include a flexural strength perpendicular to laminations of ≥ 340 MPa, a Charpy impact strength parallel to laminations of ≥ 33 KJ/m², and an electric strength perpendicular to laminations of ≥ 35 Kv at 90°C in 25# transformer oil. Moreover, the insulation resistance after immersion in water is an impressive ≥ 5*(10²*10²) MΩ, indicating its exceptional insulative properties.
The material also meets the 94-HB level for combustibility, ensuring safety in applications where fire resistance is a concern. G11 exhibits high mechanical strength at room temperature and retains its strength at a high temperature of 155°C, coupled with good electrical performance in both dry and wet states.
The thermal properties of G11 epoxy glass laminate make it an ideal choice for applications in the electrical and electronics industry, where components may be subjected to high temperatures and need to maintain their performance.
In conclusion, G11 epoxy glass laminate is a high-performance material that offers a combination of thermal resistance, mechanical strength, and electrical insulation properties. Its versatility and reliability make it a vital choice for industries seeking to push the limits of extreme thermal environments.
