Product description of light weight insulating castable
The lightweight insulating castable is mainly made of mullite hollow spheres, bubble high alumina, superfine powder, etc., and cement is used as the binder.
Features of light weight insulating castable
The lightweight insulating castable has the advantages of low density and low thermal conductivity, which not only reduces the heat consumption of industrial furnace, but also reduces the weight of furnace lining.
Applications of light weight insulating castable
Light insulating castable is suitable for medium and low temperature furnace lining, ceiling and movable roof. At the same time, lightweight insulating castables are also used for thermal insulation or single lining rotary kilns and industrial kilns.
