INSULATION FIREBRICK（IFB）
Insulating Firebrick (IFB) is a kind of highly efficient, energy saving, low-carbon, environmental protection advanced products which are manufactured according to ASTM standard. IFB series products are the best lining and insulation materials in all types of industrial furnaces in the field of Metallurgy, Aluminum, Petrochemical, Ceramics, Power and Glass. They can be applied as heat insulation or no-melt erosion parts of the working layer.The products have been widely used in the various furnaces and achieved satisfactory results.
Outstanding flexibility in dimension, coupled with high insulating efficiency expands the extensive application of IFB especially in high chemical reactivity working conditions.
