Ceramic Fiber Cotton
Description
Ceramic fiber cotton is made by melting high-purity aluminum silicate raw materials and then using the blowing method or spinning method.
Ceramic fiber cotton can be further processed into ceramic fiber blanket, ceramic fiber board, ceramic fiber paper, ceramic fiber cloth, ceramic fiber rope and other products.
