CERAMIC FIBRE BLANKET
CERAMIC FIBRE BLANKET 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. Its unique fiber layup and needling process provide CERAMIC FIBRE BLANKET with outstanding consistency, handling strength and resiliency at elevated temperatures.
CHARACTERISTICExcellent thermal stability Excellent chemistry qualityResistance to burningLow thermal conductivity Low heat storage Good obstructing voice and mechanism strengthLow shrinkageGood springiness for fibersConvenient producing and installing
Application:Joint sealing and filling insulation (kiln car, pipeline, kiln door and so on)Fiber composite (for example: grinding parcel)Internal and external lining for industrial furnaceStructure refractory and sponging soundsMaterials for hot filtrationRaw materials for further producing
