Insulating Firebrick

YESO light weight insulating firebricks are made of high-purity fire-resistant clay and alumina as raw materials with appropriate amount of organic fillers which will be burned in the production process and forming the uniform pore structure, the amount of Aluminum Oxide added increased with the levels of different temperature grades.YESO light weight insulating firebricks with advantages of light weight, small heat storage, high porosity, even porosity and excellent heat insulation effect are suitable for the temperature range of 900-1550 ℃. ‘YESO light weight insulating firebricks adopts ASTM standard, AB series made from Alumina hollow ball, Alumina powder and composite binder are formed by vibration molding and high-temperature firing with excellent high temperature performance and can be used safely at 1550 ℃.
