Lightweight insulation castable is a refractory with low density and excellent insulation properties.
It is mainly composed of high-temperature stable materials and lightweight aggregates (such as perlite, vermiculite, etc.) as well as binders and additives.
The main function of thermal insulation castable is to provide excellent thermal insulation performance, effectively reduce heat loss, and improve the energy utilization efficiency of industrial furnaces.
(1) Low density
(2) Light weight and convenient construction
(3) Low thermal conductivity and low heat capacity
(4) Excellent thermal insulation performance
(5) Energy saving and emission reduction
