Product Description

Ceramic fiber bulk is manufactured from high purity alumina-silica powder and silica sand through Special production process of spinning or blowing . Bulk fibers are available in a variety of chemistries and diameters which can service a wide variety of applications. In addition, these fibers can be further modified by chopping or by removal of the unfiberized particles (called shot). Lubricants can also be added to the fiber to enhance fiber properties.

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.
