Promat® Perlite

PROPERTIES & ADVANTAGES

Use of high quality raw materials
Dimensionally stable
Low thermal shrinkage
Sanded on all sides
High compressive strength
Low thermal conductivity
Use on the fire side
High thermal shock resistance

Fire bricks

Promat® Perlite lightweight refractory bricks are used in furnaces and thermal processing plants with low mechanical stress and without any corrosion loading.

They are particularly suitable for use in continuously operated plants, such as ceramic industry plants (chamber, bogie hearth and tunnel kilns), anode baking furnaces, coke ovens, cracker and process plants in the petrochemical industry, combustion chamber lining.
