Mullite Insulation Brick

DF Refratek insulating firebricks from high-purity refractory clays, with graduated additions of alumina for the higher temperature products, and a carefully graded organic filler, which burns out during manufacture to give a uniform, controlled pore structure.

Classification Temperature from 2300°F (1260°C) up to 3000°F (1650°C)

Application
Recommended for use as a primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kilns, flues, refining vessels and heaters, regenerators, gas producers and main, soaking pits, stress relieving furnaces, reactor chambers and similar high temperature industrial equipment.
