Epoxy Board (G-10 / G-11)
G-10: up to 130°C / G-11: up to 180°C
Main applications
G-10/G-11 epoxy board delivering structural strength and insulation together
Key Features
Excellent dielectric performance
Laminated epoxy resin and glass fiber — high dielectric strength, the global standard for PCB and insulation board
High mechanical strength
G-10 and G-11 grades — excellent compressive, tensile and flexural strength, holding accuracy through machining
G-11 for higher temperature
G-11 raises heat resistance over G-10 — stable insulation from 130°C to 180°C
Ideal for CNC machining
Drilled, milled and cut to precision — ideal for complex insulating components
Chemical and water resistance
The chemical resistance inherent in epoxy — stable properties against moisture and common chemicals
