Ceramic fiber paper takes high purity alumina silicate fiber as main raw material, using wet paper molding process to be made. The advance manufacturing technology makes the distribution of fiber be very even and the paper’s thickness and storage can also be controlled strictly, with excellent refractory and insulating effect. Ceramic fiber paper is completely free of asbestos, and is designed to be an economic replacement for asbestos paper in most applications.
