Product Introduction: FR4 fiberglass board, also known as FR4 epoxy board, is a sheet-like insulating material made by impregnating fiberglass cloth with epoxy resin as an adhesive, drying, and hot-pressing. It possesses high mechanical properties, water absorption, flame retardancy, and heat resistance, and its dielectric properties remain stable after immersion in water.

Product Features:
1. Diverse Colors: Compared to 3240 yellow, FR-4 is available in white, yellow, aquamarine, and black. The surface is smooth and bubble-free, with an attractive appearance.

2. Fire Rating: UL94V0, a ​​high fire rating. Unlike general fire ratings, UL94V0 achieves fire retardancy. It self-extinguishes shortly after being burned, protecting life and property.

3. Strong Insulation: FR-4 has excellent natural insulation properties*, maintaining excellent electrical performance in both dry and wet conditions, making it a good choice for electrical insulation components.

4. High Quality and Practicality: FR-4 remains highly adaptable to various environments. Suitable for temperatures ranging from -100℃ to 130℃.

Applications: Used in electronic and electrical insulation components, as well as insulation boards for aircraft, high-speed trains, and transformers, precision planetary gears, etc. Also suitable for products requiring high-performance electronic insulation, such as FPC reinforcing boards, PCB drilling pads, fiberglass spacers, potentiometer carbon film printed fiberglass boards, precision planetary gears (wafer grinding), precision test boards, electrical (electrical) equipment insulation support strips and partitions, insulation pads, transformer insulation boards, motor insulation components, ground gears, electronic switch insulation boards, etc.
