Pipe Insulation

perlite is often used to insulate pipes in the ground that carry steam, heated liquids, etc.

Cryogenic, Foundries and Refractories

For the same reasons Perlite is used to line Chimneys, it is used as an insulator in extreme temperature industrial applications.

Polymers, Elastomers, Paints, Fillers, Adhesives:

Fine grades of perlite work well as fillers for paints, adhesives and mortars.

Filtration

Perlite is used in storm water drains, oil fields, aquarium filters, pool filters, breweries, juice processing, pharma processing, chemical processing, and many other industries for filtration. Finer grain perlite is used to filter many substances as they will cling to the irregular shapes of perlite.

Hazmat Clean Up

Clean up oil, gas and diesel spills. These chemicals cling to the perlite granules making clean up much easier. Garages use perlite for spills.

More Unique Uses

  • Egg incubation Perlite is used to keep eggs at a more constant temperature for incubation.
  • Horse Stall Bedding
  • Barbeques and Pizza Ovens
  • Kilns
  • Cat litter replacement

Attributes

  • Weight reduction
