Mullite insulating brick is for use in applications from 1260°C to 1760°C. Each grade of brick is formulated to meet specific thermal and physical requirements. After firing each brick is machined to close dimensional tolerances. Insulating bricks are manufactured utilising exceptionally high purity clays and other ceramic materials. The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.

Features:
1. High insulating properties
2. Strong compressive strength
3. Low heat storage
4. High purity
5. Tight dimensional tolerance
6. Energy saving
7. Low impurities
