Features Mullite insulation bricks

Excellent high-temperature performance:

It has a high operating temperature, usually ranging from 1300℃ to 1600℃, and can even reach above 1700℃. It is an ideal material for the inner lining of high-temperature kilns.
Good heat preservation effect and significant energy saving: The interior has a porous structure, with a low thermal conductivity, which can effectively reduce heat loss and significantly decrease fuel or power consumption.
Lightweight and low in density: It is a lightweight refractory material, with a volume density usually ranging from 0.6g/cm³ to 1.25g/cm³. This can significantly reduce the overall structural load of the kiln, lower the cost of steel structures and foundation construction.
Good thermal stability: It can withstand sharp temperature changes without cracking or peeling, and has a long service life.
