Product Description

Product Description
INSULATING FIREBRICK
Luyang 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 vacuum and sintered under high temperature. Luyang Insulating
Firebrick is widely used as hot face refractory lining or back-up insulation in various kinds of industrial furnaces.
