Ceramic fiber paper is made of selected aluminum silicate ceramic fiber cotton as the main raw material by wet molding process.On the basis of the traditional technology, the slag removal and drying technology are improved, which are characterized by no asbestos, uniform fiber distribution, white color, no delamination, less slag balls (four times centrifugal slag removal), flexible adjustment of bulk density according to the use, great strength (including reinforced fiber), good elasticity, and strong machinability.Due to the different use temperature, it is divided into four materials, standard, high aluminum, zirconium containing ceramic fiber paper (236/436/536).
