What Is Lightweight Insulating Castable?

Lightweight castable refractory is a type of monolithic refractory made of aluminate cement, high alumina fine powder, ceramic particles, and additional additives. It has the features of light volume, high-stress resistance, and resistance to acid and acid gas corrosion. Since lightweight castable refractory has a small density and low thermal conductivity, it is also known as insulating castable or insulating castable refractory.

Application of Insulating castable refractory

The insulating castable refractory is ideal for the lining of chimneys, high-temperature flues, and air ducts because it can significantly improve their air tightness, integrity, and anti-corrosion ability. Lightweight insulating castable is also applied in petroleum, chemical, non-ferrous metals, and other industries.
