Details on FR4 Rods

FR4 rods are high-performance thermoset laminates made from woven fiberglass cloth and epoxy resin, designed to deliver superior electrical insulation and mechanical strength. With excellent dimensional stability and resistance to moisture, FR4 rods maintain their integrity in harsh environments, making them ideal for applications where electrical reliability and durability are paramount. Known for its flame-retardant properties, FR4 provides dependable performance even under elevated temperatures and challenging conditions. These rods are perfect for fabricating insulating supports, spacers, and structural components in electrical assemblies and equipment, where safety, strength, and long-lasting reliability are essential.
