FR-4 Epoxy Fiberglass Board Overview
FR-4 epoxy fiberglass board is a high-performance composite material made from woven fiberglass cloth and epoxy resin, known for its excellent electrical insulation, mechanical strength, and flame-retardant properties. The “FR” stands for “flame retardant,” ensuring safety in high-temperature environments. This material is widely used in electrical and electronic applications, including printed circuit boards (PCBs), transformers, and insulating components. FR-4’s durability, thermal stability, and resistance to moisture make it a reliable choice for industries such as electronics, telecommunications, and power generation.
