Characteristics of Perlite

Perlite is natural, sterile, ultra-lightweight, non-toxic, permanent, incombustible, asbestos-free, and virtually pH-neutral.

Why Perlite Works

Expanded perlite particles are clusters of minute, lightweight, insulating, glass bubbles. Its unique internal structure, together with a large exterior irregular surface composed of broken bubbles and surface openings provide for water and air holding capacity. Its internal structure resists thermal transmission, and crushed particles present a maze of microscopic pathways that can be used to filter and clean a wide array of liquids.

  • potting soil & propagation
  • high-performance hydroponics
  • turf enhancement
  • eco-roofs
  • lightweight concrete
  • masonry & underslab insulation
  • plaster aggregate
  • bulk filler & texturizing agent

During processing, raw ore is heated to roughly 1700°F, expanding the particles to target size and density range for the desired grade. Regular sieve analyses are performed to ensure that the final product is within spec.

The finished product is then bagged and palletized. Depending on the product or destination, the pallets may be capped with plastic and stretch wrap for transport.

Perlite Ore Products

Raw ore is available for direct purchase from our location. Ore has a number of uses, but its most commmon application is as slag skim by the foundry industry.

Bulk Bag Packaging Options

A plastic bag cap and stretch wrap can be added for moisture protection or cleanliness, for an additional fee.
