Ceramic fiber boards are high-temperature resistant, thermally insulating, and lightweight refractory materials widely used in electric furnaces and industrial insulation applications.
Brother Furnace ceramic fiber boards are manufactured using premium raw materials (calcined kaolin and alumina powder) through advanced wet vacuum-forming technology.
Combining the flexibility of fibrous materials with the rigidity of boards, they deliver exceptional thermal insulation, high-temperature resistance, mechanical strength, and durability.
