Ceramic fiber paper is made of ceramic fiber, which is made of wet process. It has high temperature resistance, chemical resistance, thermal shock resistance, low thermal conductivity, high electrical insulation strength and high elastic modulus. Its characteristics are no asbestos, long fiber, less slag ball, small density, high strength, good elasticity, easy punching, winding and other construction operations. Applicable to high temperature insulation, insulation, sealing, electrical insulation, sound-absorbing, filtration, etc., can replace asbestos products, is a high quality lightweight refractory.
