Chopped ceramic fiber bulk are manufactured from high purity raw materials: alumina powder, silica sand for the high temperature grades and zircon sand is also used. The ceramic mixture is heated in an electric furnace to temperatures in excess of 2000deg and the stream of molten material is drawn into fibers by either spinning or blowing.
NR ceramic fiber bulk are loose, long and flexible with high refractory properties, and are produced by “blown” and “spun” processes. Ceramic fiber bulk and chopped fiber show a high temperature stability and an outstanding chemical stability is complemented by their resistance to oxidation and reduction. NR ceramic fiber bulk and chopped fibers are available in a variety of length. They are used as the base for the production of blanket, moldable, and vacuum formed board and shaped products.
The chopped ceramic fiber bulk products have a widely used in high temperature industry. Such as Textile manufacture, Chimney fill, Expansion joint packing ,Wet process feedstock ,Filtration media ,Kiln car infill , Ladle insulation
