Ceramic Fiber Fireproof insulation 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 Jiuqiang Ceramic Fiber Blanket with outstanding consistency, handling strength and resiliency at elevated temperatures.
