🚀 Product Description
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. Currently, chopped fibers, vacuum formed production, and lubricated bulk fibers for textiles are all available. Ceramic bulk fibers serve as an ideal filler for various types of refractory lining and insulation tools.
