Insulation Refractories (CUMILAG)

Insulation Refractories (CUMILAG)

CUMILAG insulation refractories exhibit unique combination of chemical, mechanical stability and insulating properties. They are suitable for applications at service temperatures ranging from 1250°C to 1850°C. Bubble alumina range of insulating refractories are of light weight, have good load bearing capacity, and low heat capacity. They can be directly exposed to flame, and combustion products.

Outstanding Features

  • Very high refractoriness, structural strength
  • Low thermal conductivity, shrinkage and creep
  • High resistance to reducing atmosphere
  • Uniform pore size and distribution
