Parameters of JM26 Insulation Brick
JM26 insulation brick is a high-quality material used in high-temperature environments with excellent performance and durability. According to test results from the Kerui physics and chemistry laboratory, the product’s load softening onset temperature is approximately 1400℃ (2552℉), which means it can maintain stability and strength in high-temperature environments. In addition, the service temperature of JM26 mullite insulation brick can reach 1790℃ (3254℉). It’s suitable for various high temperature applications.
The excellent performance of JM26 insulation brick is due to the use of high-quality raw materials. These raw materials include higher alumina content and a uniformly distributed glass phase. Aluminum oxide is a high temperature resistant material that can resist chemical attack and thermal shock effects at high temperatures. The evenly distributed glass phase enhances the structural stability and durability of the bricks.
