Product Description Of Mullite insulation brick
The bulk density of lightweight heat-insulating brick is 0.60~1.25g/cm3. Working temperatures range from 900ºC to 1600ºC . Each grade of products has unique design to meet different thermal, physical and chemical demands.Jucos series lightweight heat-insulating bricks are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades. .Each face of the brick is machined grinding to the required accurate size.this material profitable by lessening fuel costs, construction costs and reducing the amount of time spent in the high temp furnace.
