EXPANDED PERLITE is an economical insulation for high and low temperature and cryogenic applications. It is widely used because of its:

  • Low thermal conductivity
  • Low cost
  • Ease of handling
  • Non combustibility
  • Low moisture retention


  • In the Casting sector as metallurgical flux, 
  • As an additive to the foundry sand , 
  • Protection of the molten metal in the pot , 
  • In the iron and steel industry for controlling of molten metal and slag, 
  • Production of refractories, 
  • Ceramic binder perlite refractory bricks,
  • Perlite refractory mortars, 
  • Used in Ceramics and Glass industries,
