1260C Mullite Insulation Brick
Mullite Insulation Brick Introduction
Mullite Insulation Brick is made from good quality and superior raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chemical demands.
Mullite Insulation Brick Characteristics:
1. Low levels of iron and other impurities
2. High mechanical intensity
3. High refractoriness, can contact with the flame directly, suitable for various atmosphere
4. High porosity, low volume density, low thermal conductivity
5. Good heat insulating performance and energy-efficient
