The K®-23 insulating firebrick (IFB) is manufactured with a unique slurry casting process that produces low thermal conductivity and good thermal-shock characteristics. Rated at 2300°F, the K-23 IFB has low density, high hot strengths, good thermal stability and ultra-low thermal conductivity. It experiences much less shrinkage than competitive products, significantly improving its lifetime. Insalcor®, a high-temperature firebrick with a use limit up to 3250°F, is produced with a manufacturing process that features excellent strength and thermal stability at high temperatures and great thermal-shock resistance for high-temperature cycling furnaces.
