High Purity Grade 28 Insulating Firebrick gains typical advantages including low thermal conductivity, 

fine thermalshock resistance,low heat containment and low iron content,meanwhile,the outstanding mechanical flexibility,coupled with high insulating efficiency expands the extensive applications of IFB in a variety of 

industrial markets.Our insulating firebrick is manufactured from highgrade refractory powder and materials in 

good purity.During the process of production,organic and multiple filling materials are injected according to the required proportion,the brick is compressed in vacuum and sintered under high temperature.
