Introduction of High Alumina Insulation Brick
High alumina poly light brick is a new type of thermal insulation brick in the series of lightweight high alumina bricks. It is mainly made of high alumina clinker and high-purity clay, filled with polystyrene foam balls. Additionally, manufacturers produce this brick burning out. It has the characteristics of high purity of raw materials, uniform pore structure, low thermal conductivity, low heat capacity, high strength as well as high dimensional accuracy. Besides, this design can withstand the high temperature of 1760 ℃. At the same time, it transfers very little heat, which can effectively improve the energy efficiency of the kiln. Moreover, this kind of high alumina refractory brick does not directly contact the kiln when it is used.
Details about Kerui High Alumina Insulation Brick
The high alumina insulation brick contains more than 48% Al2O3, which ensures good insulation effect as well as high refractoriness. Therefore, this brick has been a preferred choice for its excellent property. According to the chemical composition and physical characters, we can infer that this brick has advantages of low thermal conductivity, low heat capacity, high strength and high dimensional accuracy.
Here is the detailed technical data of high alumina insulation brick. If you’d like to customize a type of insulating soft fire brick for your business, please contact Kerui now. Kerui professional team is willing to assist.

What are Properties of Kerui Alumina Insulation Brick?
Alumina insulation bricks have low thermal conductivity, which means they are effective at insulating against heat transfer. Additionally, this property helps to reduce heat loss in high-temperature environments, Therefore, this brick is suitable for various industrial applications where temperature control is essential.
These bricks typically exhibit good thermal stability and can withstand high temperatures without significant degradation. Importantly, this stability is crucial in applications where consistent thermal performance is required over extended periods.
Kerui alumina insulation bricks have good performance in insulation effect. Therefore, this product helps to maintain the desired temperature within a furnace or kiln. These bricks can effectively reduce energy consumption by minimizing heat loss. Additonally, there are many great insulation solutions on Instagram.
Generally, insulation brick primarily focuses on thermal insulation. While it also needs to have sufficient mechanical strength to withstand handling, installation, and potential load-bearing requirements in certain applications. Therefore, the alumina insulation bricks often strike a balance between insulation and mechanical strength.
