Data Sheet
Product Details
JM23 mullite insulation brick using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM23 mullite insulation brick is the new energy saving material for insulation. JM23 mullite insulation brick are produced accordance with German industrial standard that especially for export to foreign countries.
Performance Characters:
1.High porosity.
2.Low volume density.
3.Good insulation effect.
4.High mechanical intensity.
5.Low thermal conductivity.
Application:
JM23 Mullite Insulation Brick are widely used for heat-insulating purpose in many kinds of industrial furnace. Such as electric furnace, metallurgical stove,cracking furnace in petroleum, hot blast furnace in metallurgy, ceramic roller kiln, tunnel kiln, shuttle kiln for electrical porcelain, pot furnace for glass industry, inner lining of kinds of electrial furnaces and high temperature equipment.
