Product Description:

Insulating firebrick

Insulating firebrick gains typical advantages including low thermal conductivity,fine thermal shock 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 high-grade 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.
