Insulating Firebrick(IFB)

HJM Series insulating firebricks are manufactured from high grade refractory powder and materials in good purity. During the process of production,  organics and filling materials are added according to specific proportions. By compressesd in vacuum and sintered  under high temperature, the brick has typical advantages including low thermal conductivity, good thermal shock resistance, low heat capacity and low iron content as well as outstanding mechanical flexibility which has extensive applications in variety of industrial markets.
