G10 epoxy resin laminate sheet is a composite material made of woven fiberglass cloth and epoxy resin. It has excellent mechanical strength, electrical insulation, heat resistance, and moisture resistance. In this blog post, as a high performance epoxy glass laminate sheet exporter, Blue Sun will share the performance advantages of G10 epoxy resin laminate sheet in industry.
G10 Epoxy Resin Laminate Sheet Performance Advantages in Industry
Electrical Insulation Excellence
One of the most remarkable performance advantages of G10 epoxy resin laminate sheets is their exceptional electrical insulation properties. With an electric strength perpendicular to laminations of ≥35kV (at 90℃ in 25# transformer oil), G10 sheets provide reliable insulation in both dry and wet conditions. This makes them ideal for applications where electrical safety is paramount, such as in high-voltage electrical equipment and transformers. The ability to maintain high insulation resistance even after immersion in water (≥5×(10²×10²)MΩ) further enhances their suitability for environments with moisture, ensuring that electrical systems remain safe and efficient.
Mechanical Strength and Durability
G10 epoxy resin laminate sheets are renowned for their high mechanical strength. They exhibit a flexural strength perpendicular to laminations of ≥340MPa, making them incredibly robust and capable of withstanding significant mechanical stress. This strength is not limited to room temperature conditions; G10 sheets also demonstrate strong mechanical performance at elevated temperatures, such as 120℃. This thermal stability is crucial in industries where materials are exposed to varying temperature ranges, ensuring that the structural integrity of components remains intact.
The Charpy impact strength parallel to laminations is ≥33KJ/m², indicating the material's ability to absorb and dissipate energy during impact. This feature is particularly valuable in applications where the material may be subjected to mechanical shocks or vibrations, such as in aerospace and automotive industries. The durability of G10 epoxy resin laminate sheets ensures that components made from this material have a long service life, reducing maintenance and replacement costs.
Ease of Fabrication and Versatility
Another significant advantage of G10 epoxy resin laminate sheets is their ease of fabrication. The material can be easily machined, drilled, and cut to meet specific design requirements. This versatility allows manufacturers to create a wide range of components and parts with precision and efficiency. Whether it is for complex electronic enclosures, structural supports, or custom mechanical parts, G10 epoxy resin laminate sheets can be tailored to fit the exact specifications of the application.
This ease of fabrication also extends to the material's compatibility with various manufacturing processes. G10 sheets can be bonded with adhesives, fastened with mechanical fasteners, or even welded in certain cases, providing flexibility in assembly techniques. This adaptability makes G10 epoxy resin laminate sheets a preferred choice for engineers and designers who require a material that can be seamlessly integrated into different production workflows.
Flame Retardancy and Environmental Considerations
In an era where environmental and safety concerns are at the forefront, G10 epoxy resin laminate sheets offer a balanced solution. While they are not flame retardant to the same extent as some other materials, they achieve a UL94-HB level of combustibility. This means that they are less likely to contribute to the spread of fire, providing a degree of safety in applications where fire resistance is a consideration.
Moreover, G10 epoxy resin laminate sheets are made from a halogen-free epoxy resin binder and woven fiberglass substrate. This composition is advantageous in industries where halogenated compounds are unwanted due to their potential environmental and health impacts. By using G10, manufacturers can meet regulatory requirements and contribute to a more sustainable industrial ecosystem.
Conclusion
The G10 epoxy resin laminate sheet stands out in the industrial materials market due to its exceptional performance advantages. Its combination of high electrical insulation properties, mechanical strength, ease of fabrication, and environmental considerations makes it a versatile and reliable choice for a variety of applications. As industries continue to demand materials that can meet the challenges of modern manufacturing and performance requirements, G10 epoxy resin laminate sheets are poised to play a crucial role in driving innovation and efficiency.
