1260 1430 High Temperature Refractory Insulation Fireproof Ceramic Fiber Refractory Bulk with Low Thermal Conductivity
Low Thermal Conductivity Refractory Insulation Fireproof Ceramic Fiber Bulk
Laurel Ceramic fiber bulk is manufactured from high purity alumina-silica materials through spinning operation or blowing operation.These fibers can be further modified by chopping.In addition,Lubricant can be added to the fibers.
Ceramic fiber bulk serves as the foundation for fiber products such as blanket,board,paper and other vacuum-formed products. They are available in a variety of chemistries and diameters which can offer a wide variety of applications.
