Industrial Grade Perlite

A look inside of the perlite factory

Expanded perlite comes in a wide variety of sizes and densities making it customizable to different applications. It is also ultra-lightweight, sterile, chemically inert, permanent, incombustible, rot and vermin resistant, asbestos-free, pH neutral, free of organic impurities, and having a large surface area. Perlite can safely be used over a wide range of temperatures.

Industrial applications include cryogenic tank insulation, formed thermal insulation products and refractory brick, powdered filteraids and baghouse pre-coat, commercial adsorbents, and much more. Unexpanded ore is used in the foundry industry for hot topping or slag gel on molten metal.
