Codes are Mimosi reference codes – just quote the code in your request. Values are typical; exact values are given in the data sheet with our offer.

How to choose

  1. Match grain size to your furnace and end product: fine grades for plaster and filter perlite, medium and coarse for horticultural and loose-fill grades.
  2. Combined water drives expansion: too little gives poor expansion, too much gives a brittle, dusty product. Check this value on the analysis report.
  3. Ore quality directly affects yield: lower-grade ore breaks down into more fines and dust in the furnace. Start a new supply with a trial lot.
  4. Moisture should stay below 1 %; prefer closed containers or big bags to keep the ore dry in transit.

Description

Perlite is a volcanic glass that expands many times its volume when heated. Because expanded perlite is uneconomical to ship over long distances, the raw ore is shipped and expanded in the buyer's country.

We ship raw perlite in the grain size that suits your expansion furnace, together with an analysis report. A regular shipment plan and a long-term supply agreement can be set up around your annual consumption.

For a quotation, simply tell us your furnace type, the grain size you need and your monthly consumption.
