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.
