Advantages of G10 Epoxy Fiberglass Laminate in High-Performance Applications

In the realm of advanced materials, G10 epoxy fiberglass laminate has emerged as a standout choice for its exceptional combination of mechanical strength, electrical insulation, and ease of fabrication. This material, a non-halogenated variant of the widely recognized FR-4, is crafted from a halogen-free epoxy resin binder and woven fiberglass substrate. Its unique properties make it an ideal candidate for a variety of applications, particularly in environments where halogenated compounds are undesirable. In this blog post, Hangzhou Blue Sun will share with you the advantages of G10 epoxy fiberglass laminate for sale.

Superior Mechanical Strength

The G10 laminate boasts a flexural strength of ≥ 340 MPa, perpendicular to the laminations. This high mechanical strength is not only evident at room temperature but also remains robust at elevated temperatures, such as 120°C. Such resilience is crucial in structural applications where the material must withstand significant stress without compromising its integrity.

Impact Resistance

With a Charpy impact strength of ≥ 33 KJ/m² parallel to the laminations, G10 demonstrates its ability to absorb and withstand shock without fracturing. This attribute is particularly valuable in cryogenic applications and any scenario where the material may be subjected to sudden impacts.

Electrical Insulation

Electrical strength is a critical consideration for materials used in electrical and electronic applications. G10 epoxy fiberglass laminate excels in this regard, offering an electric strength of ≥ 35 Kv perpendicular to the laminations, even when tested at 90°C in 25# transformer oil. Moreover, its insulation resistance after immersion in water is ≥ 5*(10²*10²) MΩ, ensuring reliable performance in both dry and wet conditions.

Flame Retardancy

Safety is paramount in industries where materials are exposed to potential fire hazards. G10's UL94-HB rating indicates a moderate level of flame retardancy, reducing the risk of fire spread and providing a safer option for use in electrical panels and other equipment.

Ease of Fabrication

One of the key advantages of G10 is its ease of fabrication. This characteristic simplifies the manufacturing process, allowing for quicker turnaround times and reduced production costs. The material's workability also enables the creation of complex shapes and designs, catering to the specific needs of various applications.

Environmental Considerations

As a halogen-free epoxy resin binder, G10 aligns with the growing demand for environmentally friendly materials. The absence of halogens means that it does not release harmful halogenated compounds during manufacturing or disposal, making it a more sustainable choice for industries committed to reducing their environmental impact.

Conclusion

The G10 epoxy fiberglass laminate's blend of high mechanical strength, impact resistance, electrical insulation, flame retardancy, and ease of fabrication positions it as a leading material for a range of high-performance applications. Its environmental benefits further solidify its appeal in an industry increasingly focused on sustainability.
