Product Information
JM23 mullite insulation brick is a type of insulation material made from high-purity mullite as its main component. The bricks are manufactured by incorporating alumina powder and then subjecting them to high-temperature sintering. These bricks are specifically designed to provide excellent insulation properties and are considered a new energy-saving material.
JM23 mullite insulation bricks adhere to the German industrial standard, ensuring their quality and suitability for export to foreign markets. They are carefully produced to meet the requirements and specifications of international customers seeking reliable insulation solutions.
