The versatility of fiberglass epoxy boards allows for their use in a multitude of applications. In energy storage cabinets, they are primarily used to insulate and separate individual battery cells or modules from the metal racking system. This prevents electrical shorts and reduces the risk of fire or electrical hazards. Beyond energy storage, FR-4 boards are commonly found in printed circuit boards (PCBs) for electronics, aerospace components, and automotive systems, where reliable insulation is necessary.
