G10 Fibreglass Epoxy Plate

High-Strength Electrical Insulation & Structural Sheet

G10 fibreglass epoxy plate is a glass-reinforced epoxy sheet built for strength and reliable electrical insulation. Because manufacturers press woven glass cloth with epoxy resin under heat and pressure, the material forms a dense and stable laminate. As a result, G10 delivers consistent mechanical strength and dependable dielectric performance.

In addition, its balanced properties allow it to handle both structural loads and insulation demands in the same part.

Performance Characteristics

G10 provides high flexural and compressive strength. At the same time, it offers strong electrical insulation and low moisture absorption. Consequently, parts made from G10 remain stable in humid or electrically active environments.

Moreover, the sheet machines cleanly and holds tight tolerances. Therefore, engineers choose G10 when they need strength, insulation, and ease of fabrication in one material.

Electrical & Thermal Properties

G10 maintains steady dielectric strength under electrical load. Furthermore, its epoxy-glass structure limits moisture uptake, which helps protect long-term insulation performance.

Although G10 handles moderate heat well, it is best suited for applications that do not require extreme temperature resistance. However, when higher heat performance is needed, G11 or FR5 grades provide better thermal capability.

Machining & Fabrication

G10 fibreglass epoxy plate machines easily with carbide tooling. Consequently, it supports routing, drilling, tapping, milling, and waterjet cutting with clean edges.

Because the laminate contains glass fibres, operators should use proper dust extraction during machining. In addition, the sheet bonds well with epoxy adhesives, which allows simple integration into composite or mixed-material assemblies.

Typical Applications

Because of its strength and insulation properties, G10 is widely used in:

• Electrical switchgear panels
• Transformer supports and spacers
• Industrial machine components
• Wind energy electrical housings
• EV battery insulation parts
• Aerospace non-conductive brackets
• Marine electrical mounting panels
• Construction insulation systems

Therefore, industries rely on G10 when electrical isolation and mechanical stability must work together.

G10 vs G11 – What’s the Difference?

Both G10 and G11 use glass-reinforced epoxy construction. However, G11 handles higher operating temperatures. Therefore, selecting the correct grade ensures long-term reliability under both load and heat.
