Mullite insulating brick

Description:

Mullite insulating brick is an insulating material made of organic matter as a burn-in agent to increase the porosity of the refractory material. The utility model has the advantages of high porosity, small bulk density, good heat insulation effect, high mechanical strength, small thermal conductivity and long service life, and is an energy-saving thermal insulating refractory material which is indispensable for laying various industrial furnaces.

Advantage:

High mechanical strength, small thermal conductivity, long service life

Application:

Insulating part of various industrial furnaces
