Haimo Insulating Firebrick is made from high-purity refractory powder and organic fillers which burn out during manufacture to give a uniform and controlled pore sture. The brick is compressed in vaccum and sintered under high temperature. Haimo Insulating Firebrick is widely used as hot face refractory lining or back-up insulation in various kinds of industrial furnaces.
