Introduction
The CASI Nano Insulation Brick is used in a variety of industrial furnaces for backup insulation.

CASI Nano Insulation brick is our innovative products made from selected Al2O3, SiO2 and CaO raw materials, manufactured by fully automatic production lines. It seamlessly combines the high strength of insulation bricks with the low thermal conductivity of ceramic fibers, while have much better linear change after reheating. The product features low bulk density, low thermal conductivity, and good strength.

 

The bricks are used as backup insulation of many industrial furnaces such as roller hearth kiln, tunnel kiln, glass tank, hot blast stove, reheating furnace, aluminum smelter, carbon baking furnace, flue, hot wind duct, etc.
