It is made of special ceramic long-fiber that is produced by the melting of very pure raw materials in double surface meeding process with out binders and with good stability in a large range of temperature. The process of double surface needing increase interweaving and tensile strength
Characteristics:Low thermal conductivity and low heat storage. Excellent thermal stability and thermal shock resistance. Excellent erosion resistance
Excellent heat insulation,fire proofing and procssing function.
Application:Industrial furnace,heaters,inside walll of hige temperature rube. Electric power furnace,nuclear power station and heat insulation.
Fire proofing and heat insulation of high building.
