Detailed Product Description
The above photo shows red colored insulating brick, which is used chamotte as raw material.
DOUBLE EGRET is the specialized manufacturer and exporter of insulation and refractory material in north of China with more than 10 years' history. Our brand CCE WOOL is well known in the world, enjoying good maket in Europe, America, Southeast Asia and Mid East.
Chamotte insulating brick, also named light clay brick,using chamotte as raw material, is made by adding combustible, gas evolution method, or foam method. Chamotte insulating brick is a kind of porous material with Al2O3 content 30-46%. The refractoriness is almost the same as fire clay brick. But compressive strength, slag resistance and corrosion resistance are much lower.
