YUFENGREC ® INSULATING FIRE BRICK (IFB) are made of high-grade refractory powder and material in good purity . During the process of production , organic and multiple filling materials are injected according to there required proportion ,the brick is compressed in vacuum and sintered under high temperature , for use in applications from 2300ºF (1260ºC) to 3000ºF (1650ºC).
Each type is formulated to meet specific thermal and physical requirements, and after firing is machined to precise tolerances. Made from high purity refractory clays and other ceramic raw materials, these IFB contain carefully graded organic filler which is burned out during manufacture to give a uniform, controlled pore structure.
