Product details:location : Home > Products > Fireclay Insulating Brick

 JK series insulation fireclay bricks are made from high purity raw material according to different brick type to meet different requirement.
 
They are ideal thermal insulation material usually used in industrial furnaces and heating pipe.
 
JK insulation bricks have excellent properties as light weight, low ferrous, low shrinkage, atmosphere erosion resistant and so on.
 
Features and advantage:
1. Light weight;
2. Low density;
3. High strength, good thermal shock resistance;
4. Low heat storage, low thermal conductivity;
5. Saving energy;
6. Precise size;
7. Good thermal insulation effect;
8. Good quality and low price.
 
Application:
It is widely used as a primary hot face refractory lining or as back-up insulation behind other refractory in furnace(such as carbon furnace, cracking furnace, heating furnace for oil refining, roller kiln, tunnel kiln.), flues, refining vessels, heaters, regenerators and similar high temperature industrial equipment.
