RZ ceramic fiber spun/blown bulk is a high temperature refractory insulation material manufactured from alumina and silica fibers, with the characteristics of stable performance, long fiber, even diameter,good tensile strength, less shot, excellent thermal stability and white color etc.

RZ chopped ceramic fiber removed the shots in the process of cutting,which improved the product performance further. 

The classification temperature(℃)：1050,1260,1360,1450 

RZ Ceramic Fiber Bulk Features:                                            

• Excellent chemical and thermal stability        

• Low thermal conductivity and Low heat storage

• Excellent sound-absorbing capability and mechanism strength          

• Low Thermal shrinkage ﹡No any corrosive materials ﹡Asbestos free     
        

RZ Ceramic Fiber Bulk Applications：

•  As infill for roofs and walls of certain types of furnaces and kilns

•  Be used to manufacture of felt, board, paper, vacuum shapes, textiles etc.

•  As seals for furnace and tube 

•  Be used as composite materials in cement, plastic, resin and metal etc.
