Our LDSIN Series Insulating Castable is specifically formulated to provide superior thermal insulation as a monolithic lining or backup layer. By incorporating lightweight aggregates such as perlite, vermiculite, expanded clay, mullite, or bubble alumina, we create a castable with significantly reduced bulk density and thermal conductivity. This series covers a broad working temperature range from 800°C to 1700°C, offering a versatile and easy-to-install solution to minimize heat loss, improve furnace efficiency, and reduce energy consumption across diverse industries.
