Description
As the crucial and staple materials for producing ceramic fiber blanket, board,module and other formed products, Zhongzi 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 for vacuum formed production, the lubricated bulk fibers and the fiber for textiles are all available. Zhongzi ceramic bulk fibers serve as an ideal filler for various types of refractory lining and insulation tools.
