In addition to the characteristics of hard texture, excellent toughness and strength, ceramic fiber board also has excellent resistance to wind erosion. Moreover, besides it is light in weight and does not expand when heated, it is also convenient in construction, and easy to shape or cut. It is an ideal energy-saving material for kilns, pipes and other thermal insulation equipment.
