Paper phenolic rods are high-performance laminates based on a cellulose paper substrate impregnated with phenolic resin. These rods exhibit excellent mechanical strength, high dielectric properties, and superior moisture resistance, making them suitable for demanding industrial and electrical applications. Grade XXX – Standard grade, widely recommended for general mechanical use, applications involving radio frequencies, and environments with high humidity. Grades XX and X – Available upon special request, suitable for applications requiring specific mechanical or electrical properties. These rods are ideal for insulating components, mechanical supports, and structural parts where stability, durability, and electrical insulation are critical.
