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 insulating brick is a new type of lightweight mullite bricks with 50-80% Al2O3, mullite (3Al2O3·2SiO2) as main crystalline phase and binder phase. Jm23 insulation brick is widely used for working face inner lining that contact flame directly because high temperature stability and high strength, low thermal expansivity and good thermal shock resistance.
The Mullite Insulating Brick Light Weight Insulation Brick Refractory Brick manufactured by CH Refractories with stable quality and best price. The mullite bricks are exported to many countries regularly, such as Saudi, Malaysia, Indonesia and so on, which got long-term cooperation and high praise from our customers. We are expecting 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.
