【Product introduction】
Ceramic(Aluminum silicate) Fiber Blanket is made of special aluminum silicate ceramic fiber filaments through a special double-sided needling process. After the double-sided needling process, the interlacing degree of the fibers, the delamination resistance and the flatness of the surface of the tensile strength are greatly improved. It has the advantages of light weight, no slag ball and easy construction.
