High Temperature Thermal Insulation Ceramic Fiber Refractory Wool

Product Description

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.
