Product Description



The JM series lightweight heat insulation bricks have a bulk weight of 0.6 to 1.25g/cm3 and a service temperature range of 1300 ° C to 1600 ° C, and each grade has a unique design to meet different thermal, physical and chemical requirements. GM series light insulation bricks are made of high quality ultra-pure raw materials, and the packing is strictly classified according to the grade. These fillers are fired during the manufacturing process to form a uniform pore structure. Each face of the brick is machined to the exact dimensions required. This material benefits by reducing fuel costs, construction costs, and time spent in high temperature furnaces.
