Heat Resistant Insulation Mullite Bricks JM23 JM26 JM28 Series
Insulation Brick
Heat Resistant Insulation Mullite Bricks JM23 JM26 JM28 Series
Mullite insulating brick made by CH refractories is JM series
according to international standard.
Because JM23 insulation brick with smaller bulk density whose
strength is not as strong as heavy weight fire bricks, when
delivering, CH Refractories will package mullite insulating brick
with special packages to protect mullite bricks from damage.
Mullite refractory brick has the characteristics of high softening
temperature under load, compact structure, good corrosion
resistance and low porosity. It is mainly used in furnace body and
bottom of blast furnace, top of hot air furnace, regenerative
chamber of glass melting furnace, dead Angle furnace lining of
petroleum cracking system, ceramic sintering kiln, etc.
The Heat Resistant Insulation Mullite Bricks JM23 JM26 JM28 Series
manufactured by CH Refractories with stable quality and best price.
The insulation bricks are exported to many countries regularly,
such as Saudi, Malaysia, Indonesia and so on. We are waiting for
long term cooperation with you.

The specification of the mullite insulation brick:
1.Low thermal conductivity,good thermal insulation effect.
2.Low melting temperature,due to the low thermal conductivity,the
mullite lightweight thermal insulation brick accumulated little
heat,and it can save much energy obviously during the process of
intermittent operation.
3.With low content of impurity such as alkali metal oxides,high
refractoriness and content of aluminum,it can keep good performance
in the reductive atmosphere.
4.High thermal compressive strength.
5.With high precise of the appearance size,it can increase the
speed of the construction,reduce the usage of the fire clay and can
keep the strength and stability of the construction.So at last it
can length the life of the lining.
6.The mullite thermal insulation brick can be made in different
shape so that reduce the quantity of usage and the joints of bricks
during the construction.The brick can be directly used as the
lining of the high temperature of the kiln and now widely used in
shuttle kiln,roller kiln,glass and petrochemichal industry kilns.
