Ceramic fiber insulation board is an aluminum silicate fiber board, which is made of the refractory material and can maintain good mechanical strength after heating, compared with fiber carpets and mats,Ceramic fiber insulation board is a stiffer fiber-reinforced product with support strength. Besides the superior property of the ceramic fiber board, it also have the hard texture, excellent toughness and strength, and excellent resistance to wind erosion. Heating is not expansion, light weight, easy construction, can be arbitrary shear bending, so it is an ideal energy-saving material for furnaces, pipes and other insulation equipment (Also supply ceramic fiber board with alumina foil).
