Usually the density of Insulation Castable is from 0.8g/cm3 to 1.5g/cm3, the raw material can be perlite, vermiculite, light weight clay, light weight mullite or bubble alumina according to the different service temperature.
Light weight Bubble Alumina Based Insulation Castable is fully bubble alumina based, the max service temperature can reach 1700℃, we use CA70 cement as binder and also add some α alumina powder to improve the high temperature performance, the density can be from 1.5-1.6g/cm3.
