G10 Epoxy Fiberglass Sheet

G10 epoxy sheet is a composite laminated material manufactured by impregnating electronic-grade alkali-free glass fiber fabric with epoxy resin as a binder, followed by layer-by-layer lamination under high temperature and pressure.

Core Composition:

• Reinforcing Material: Glass fiber fabric — provides extremely high mechanical strength and dimensional stability.

• Binder: Epoxy resin — offers excellent electrical insulation, chemical resistance, and bond strength.

Key Characteristics:

• Exceptional Mechanical Strength: Features an outstanding strength-to-weight ratio, with high tensile, compressive, and flexural strength, ensuring durability and ruggedness.

• Excellent Electrical Insulation: Maintains high dielectric strength and resistivity in both dry and humid environments, making it an ideal insulating material.

• Low Water Absorption: Its dense molecular structure minimizes moisture uptake, allowing it to retain performance and dimensional stability even in humid conditions.

• Good Chemical Resistance: Resists most solvents, acids, and bases, providing strong corrosion resistance.

• High Dimensional Stability: Exhibits minimal shape or size changes under varying temperatures and humidity levels.

• Ease of Machining: Can be processed using standard metalworking equipment, including drilling, milling, cutting, turning, and grinding.
