Information @ a Glance

  • Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.
  •  It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.
  • Perlite is not a trade name but a generic term for naturally occurring siliceous rock.
  • The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.
  • This expansion is due to the presence of two to six percent combined water in the crude perlite rock.
  • When quickly heated to above 1600F (871C), the crude rock pops in a manner similar to popcorn as the combined water vaporizes and creates countless tiny bubbles which account for the amazing light weight.
  • Crude perlite ore is mined, crushed, dried in a rotary dryer, ground, screened, and shipped to expansion plants.
  • Horizontal rotary or vertical stationary expansion furnaces are used to expand the processed perlite ore.
  • Processing of the non-metallic minerals on the mine site involves crushing and grinding of the ore,the separation of the valuable minerals from the matrix rock through various concentration steps; and at some operations, the drying, calcining, pelletising and packaging of concentrates to ease further handling or refining.
  • Annual world production of unexpanded perlite has increased by some 20%.
  • Demand for perlite in horticulture continues to grow.
  • Estimated world production of around 3.1Mtpy is believed to represent just 60% of installed production capacity.
  • The uniqueness of this universal paste lies in the Perlite-based technology which makes for efficient cleaning, and a highly polished effect in a single application.
  • Perlite used In the construction and manufacturing fields, it is used in lightweight plasters and mortars, insulation, ceiling tiles and filter aids.
