Product Description

SSW Series Insulating Bricks

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 firing ,which meets the requirement of construction.
