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 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 compressd in vacuum and sintered under high temperature.
