Paper (X, XX, XXX, XP)
Grade X paper is a durable, low-cost laminate with good compressive, tensile and flexural strength. Grade XX is suitable for general purpose electrical applications. It has good mechanical properties and excellent moisture resistance. Grade XXX is a cost-effective laminate with good mechanical properties, high dielectric strength and good moisture resistance. All are available in punching grades.
