We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of JM30 insulation brick
JM30 insulating brick is made of high-purity refractory clay with gradually increasing alumina content. During the production process, it is carefully saturated with organic fillers to form a uniform and controllable porous structure.
Advantages of JM30 insulation brick
- Low thermal conductivity. It has good heat preservation effect and can make the furnace wall thinner.
- Low heat capacity: due to its light weight, low thermal conductivity and less heat energy stored in the light mullite brick series products, it has obvious energy-saving effect in intermittent operation kilns.
- Low impurity content: its iron and alkali metal low melt content is very low, so the fire resistance is high. High aluminum content makes it maintain good performance in reducing atmosphere.

Application of JM30 insulation brick
JM30 insulating brick can be used as the first layer of refractory lining or back insulation layer behind all other refractory layers for furnaces, ovens, fire tunnels, refining rooms and heating furnaces, regenerators, natural gas production plants and pipelines, outlook furnaces, stress relief furnaces, reactor chambers and similar high-temperature industrial devices.
