EPOXY GLASS FIBER (FR4 / G10)

EPOXY GLASS FIBER (FR4 / G10)

FR4 is a premium composite material with Flame Retardant properties, manufactured by combining high-strength woven fiberglass cloth with epoxy resin. The number '4' in its name represents the material's fire resistance standard; with its flame-retardant and self-extinguishing structure, it is indispensable for safety-critical projects. Thanks to its outstanding electrical insulation values and dielectric strength, it is considered the industry standard primarily in PCB (Printed Circuit Board) production, as well as in electrical panels, transformer insulation, and high-voltage equipment. Featuring near-zero moisture absorption and high mechanical rigidity, FR4 maintains its dimensional stability even under harsh environmental conditions. It offers a reliable, durable, and high-performance solution for both electronic and structural engineering applications.

Epoxy Glass Fiber (FR4 / G10): The Standard for Industrial Reliability

In modern engineering, the transition from metal to advanced composites is driven by the need for materials that are non-conductive yet mechanically as tough as steel. Epoxy Glass Fiber (FR4 / G10) is the definitive solution for these demanding requirements. This high-pressure thermoset laminate combines woven fiberglass with a specialized epoxy resin, creating a material that is virtually indestructible under normal industrial operating conditions.

Why FR4 / G10 is the Industry Standard

  • Flame Retardancy: The "FR" in FR4 stands for Flame Retardant, a critical safety requirement in the electrical, electronics, and automotive sectors. Unlike standard plastics, FR4 does not support combustion and maintains its structural integrity at continuous operating temperatures up to 130°C (Class B insulation).

  • Precision Machinability: Despite its extreme hardness, FR4 can be precisely machined into complex geometries, including custom gears, threaded rods, and intricate insulating profiles.

  • Chemical Immunity: It is highly resistant to most industrial oils, solvents, and acids, making it an ideal choice for harsh chemical processing environments.

  • Dimensional Stability: With near-zero thermal expansion and moisture absorption, components made from Epoxy Glass Fiber retain their exact measurements and mechanical strength for decades.

We offer premium Epoxy Glass Fiber in a wide range of thicknesses, available in sheets, tubes, and rods. Every piece is rigorously inspected to meet international quality and safety standards, ensuring that your industrial insulation remains robust and reliable.
