Ultra-lightweight Insulating Castable

 

The ultra-lightweight insulating castable developed by Rongsheng is made of high-temperature high-strength light-weight nano-aggregate, aluminate cement and high-alumina fines with various additives, which has the advantages of small bulk density, high crushing strength, low

thermal conductivity, excellent thermal insulation, energy saving and consumption reduction, convenient construction, and so on. It can reduce the thermal energy consumption of industrial furnaces and reduce the weight of furnace lining.
