Industrial Uses and Applications of Perlite

Industrial uses of PerliteWhen perlite ore is heated, it grows up to 20 times its original size and forms clusters of microscopic glass bubbles that are ideal for industrial uses.

Enhanced by Perlite

Perlite industrial uses are so vast, many consumers are only a few feet away from something enhanced by the mineral—whether or not they know it!

  • Ceiling tiles
  • Pipe insulation
  • Roofing board
  • Fire-rated door cores
  • High-temperature insulation
  • Molten metal topping
  • Joint compound, spackling
  • Cryogenic insulation
  • Filtration
  • Lightweight fillers
  • Decorative stone
  • Fireplace chimneys
  • Specialty stoves
  • Wood fired bread and pizza ovens

Perlite Filler Size and Shape

Perlite glass fillers consist of broken, expanded perlite particles that form flake-like, flat particles with an interlocking, three-dimensional structure. This structure helps reduce shrinkage upon drying or curing, maintaining the physical dimensions of the host material. Typical uses for perlite glass flake fillers are:

  • Water-based construction compounds
  • Paints
  • Asphalt
  • Concrete
  • Plaster
  • Resin-based castings
