Mullite Insulating Bricks (IFB 23 26 28)

Product Description

Mullite insulating bricks characteristics and advantages:
1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction.
5. Max service temp: Up to 1730C (3160F)
