Light Weight Insulating Castable


Item Code:A4304

Light weight insulating castable, a kind of monolithic refractory castable, is mainly made from light weight refractory aggregate and mixed with powder materials, high alumina cement adhesive, dispersant, plasticizer, coagulant and other additives.


Light weight insulating castable has been widely used in insulating layers and linings of furnaces, thermal equipment, flues and chimney in metallurgy, machinery, petrochemicals, electric power, building materials and other industrial sectors.


Light weight insulating castable owns characteristics of high working temperature, low thermal conductivity, good thermal insulation, small bulk density, weight reducing of furnace structure, etc.
