Premium FR5 Fiberglass Epoxy Insulation Boards For Extreme Temperature & High-Performance Applications

FR5 represents the pinnacle of performance in standard epoxy-glass laminates. At STK Tape, we provide this advanced material to engineers and manufacturers who cannot compromise on reliability under thermal or electrical stress. FR5's core advantage is its ability to maintain its structural integrity and insulating properties where temperatures soar and power densities are high. This makes it the substrate of choice for applications where failure is not an option. We support your most challenging projects by not only supplying the raw FR5 board stock but also by offering precision machining services.
