G10 epoxy fiberglass sheet is a laminated insulation material made from glass fiber cloth and epoxy resin under high temperature and high pressure. It is a high-performance electrical insulation composite material. Due to its excellent mechanical strength, electrical insulation properties, and thermal resistance, G10 epoxy sheets are widely used in the power, electrical, electronics, and mechanical industries.

G10 Epoxy Sheet properties

Excellent Electrical Insulation
G10 provides high insulation resistance and dielectric strength, making it suitable for high-voltage electrical equipment.
High Mechanical Strength
The glass fiber reinforced structure gives the material excellent bending strength and impact resistance.
Good Heat Resistance
The long-term operating temperature can reach approximately 130°C (Class B insulation).
Good Dimensional Stability
It is less affected by temperature and humidity and maintains stable dimensions.
Easy to Machine
G10 sheets can be processed by CNC machining, drilling, cutting, and milling, making them suitable for manufacturing various insulation components.

Application of  G10  epoxy fiberglass sheet

G10 features extremely high mechanical strength, excellent electrical insulation performance, and very low water absorption, making it suitable for a wide range of applications.
