Ceramic Fiber Board by adding a small amount of high-purity alumina silicate fiber binders, which is made through automation control and continuous production process, with a host of features such as precise size, good flatness, high strength, lightweight, excellent thermal shock resistance and anti-stripping, which can be widely used for insulation in the linings around and at the bottom of kilns, as well as ceramic kilns fire position, craft glass mold and other positions.
Characteristics：
Non-brittle material, good elasticity
Good sound insulation;
Accurate sizes and good flatness
Kiln construction: Hot surface refractories, heavy refractory back linings, expansion joints.
Light industry: Industrial and household boiler combustion chamber lining;
Petrochemical industry: as high-temperature furnace hot surface lining material;
Craft glass: As craft glass or other deep-processed and molded products mold;
