JUCOS Refractories > Preheating Insulation Material > Insulation Ceramic Fiber Bulk
Product Details

As the crucial and staple materials for producing ceramic fiber blanket, board, module and other formed products, ceramic bulk fiber is normally manufactured from high purity raw materials-alumina powder, silica sand through unique production techniques of spun or blowing, these bulks are loose, long and flexible with fine thermal properties, at present, the chopped fibers are vacuum formed production, the lubricated bulk fibers are the fiber for textiles are all available. Ceramic bulk fibers Serve as ab ideal filler for various types of refractory lining and insulation tools.
