Product Description
Product Overview:
Light-weight insulating brick is made by mixing hollow microsphere, microsphere, pearlstone and bonding agent as per certain ratio, pressing molding, and burning under high-temperature. It can be divided into such five grades as NG-1.3, NG-1.0, NG-0.8, NG-0.6 and NG-0.5 as per physical and chemical indexes. It’s mainly used for heat insulation of industrial kilns to realize energy saving.
