Clay Insulation Bricks
Clay Insulation Brick Properties
High porosity, usually 40%~85%.
The low volume density, the low volume density is lower than 1.5g/cm3
Low thermal conductivity, generally less than 1.0W (m.K)
As the insulation material of industrial kiln, it can reduce heat loss, save energy, and reduce the quality of thermal equipment.
