Product Description : The ceramic fiber 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 high temperature electric furnace and the stream of molten material is drawn into fibers by either spinning or blowing. It is produced by advanced "blown" and "spun" processes. Ceramic fiber bulk shows a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to oxidation and reduction.
Product Features: Excellent thermal and chemical stability Low thermal conductivity and heat storage Excellent thermal shock resistance and sound-absorption capability No bonding agent and corrosive substance Asbestos free
Application: Material of fiber blanket, paper, textile and vacuum products Chimney and kiln car fill Expansion joint packing Wet process feedstock Mouldables/ Mastics feedstock Ladle insulation
