Product Description
Introduction to the production of Refractory bricks by Factory - Tunnel Kiln

Product Description:
Mullite insulation brick
Mullite insulation brick is a lightweight firebrick, its main component is mullite (3Al₂O₃-2SiO₂), which is a high fire resistance, low thermal conductivity of the mineral material. Mullite insulation bricks are commonly used as insulation layers for industrial kilns and thermal equipment. Its main use is to provide thermal insulation while reducing heat loss and improving the thermal efficiency of the equipment.
