FR4 epoxy boards come in various colors. The standard is a natural water green, with yellow also available. Others can be customized according to customer requirements, including white FR4 epoxy boards, black FR4 epoxy boards, blue FR4 epoxy boards, and many other colors. FR4 epoxy boards have high mechanical properties, excellent insulation, can withstand high temperatures, have corrosion resistance, and are moisture-resistant, suitable for a wide range of machining processes.

       FR4 epoxy boards offer excellent flame retardancy, are not prone to catching fire or charring, and maintain their insulating and voltage resistance in both dry and wet conditions. They are a great choice for high-end insulation and high-voltage product accessories.

       Standard FR4 epoxy board sizes include 1020mm x 1020mm, 1020mm x 1220mm, 1220mm x 1220mm, 1020mm x 2020mm, and 1220mm x 2440mm. Thickness: 0.1mm - 380mm. Custom sizes and thicknesses can also be produced upon customer request.

       FR4 epoxy boards have a different fire rating than general insulating materials, achieving both fire prevention and flame retardancy. They can extinguish themselves within 2-3 seconds after the material catches fire due to high temperatures or open flames, providing significant protection for the safety of customers' lives and property. Giving customers peace of mind.

       FR4 epoxy boards offer excellent insulation properties, maintaining their insulating and voltage-withstanding capabilities in various environments. They are highly adaptable, functioning effectively from -100℃ to high temperatures of 180℃. This is why many high-voltage equipment manufacturers choose FR4 epoxy boards for their insulation components.

       Section 4: Product Applications:

       FR4 epoxy boards are used in the processing and carving of components for motors and electrical equipment, and can also be used in transformer oil. They are also suitable for electrical and electronic insulation components, as well as for insulation boards in aircraft, high-speed trains, transformers, power plants, shipyards, metallurgy, copper smelting, iron smelting, and many other industries. Electrical (electrical) equipment load bars, insulation pads, grinding gears, electronic switch bases, etc.
