G10 high temperature epoxy resin fiberglass laminated sheet

product description

Description of G10

Colorful G10 fiberglass laminated board is also called epoxy resin alkali-free fiberglass laminated board. It is made by electronic grade fiberglass cloth impregnated with heat-resistant epoxy resin under hot pressing with stable electrical insulation property, good flatness, smooth surface and standard thickness tolerance. Colorful G10 fiberglass laminated board produced by ZTelec Group has various colors and types and its insulation class is F class.

Application of G10

It is suitable for products with high requirements on electronic insulation performance，for example, FPC reinforced board, high temperature resistant board for wave soldering，precision star wheel, PCB test stand, deflection coil terminal board, electronic switch insulation board, copper clad plate substrate, etc. It can also be used to make insulation partitions and pads for electrical equipment, insulation parts for transformer and motor, etc.

Advantages of G10 glass epoxy composite material

Strength and Durability: G10 material combines an epoxy resin binder with a glass epoxy composite, resulting in a robust and resilient material. Its high strength and durability make it suitable for demanding environments.

Chemical Resistance: The epoxy resin binder in G10 provides excellent resistance to chemicals, heat, and UV light. This makes G10 ideal for use in humid or moist conditions without degradation.

Electrical Properties: The glass epoxy composite contributes to G10’s exceptional electrical insulation. It consists of glass fibers and epoxy resin, creating a strong and rigid structure. Higher glass-to-epoxy ratios enhance mechanical strength and dielectric properties.

Versatility: G10 is widely used in industrial laminates, circuit boards, and even cryogenic equipment. Its combination of strength, chemical resistance, and electrical insulation makes it a versatile choice12.

Fire Safety: For additional fire safety, consider FR4, a variant of G10. It shares G10’s high strength and good electrical insulation properties while offering enhanced fire resistance.

Can G10 be used in high temperature environments

Certainly! G10, being a glass epoxy composite material, exhibits good performance in high-temperature environments. Here are some key points regarding its suitability:

Thermal Stability: G10 is designed to withstand elevated temperatures. Its glass fibers provide thermal stability, allowing it to maintain its structural integrity even when exposed to heat.

Temperature Range: The specific temperature range depends on the resin used in the composite. Generally, G10 can handle temperatures up to approximately 130°C (266°F) without significant degradation.

Derating: Keep in mind that as the temperature increases, the material’s mechanical properties may be affected. It’s essential to consider derating factors when using G10 in high-temperature applications.

Insulation Properties: G10 remains an excellent electrical insulator even at elevated temperatures. This makes it suitable for applications where electrical insulation is crucial.

If you want better higher temperature electrical insulation, you can use G11 or G7
