Nordisk® Perlite is hydrated, naturally occurring volcanic rock. Its unique structure consists of numerous concentric layers, similar to the layers on an onion.
Its natural colour ranges from pearl grey to off white. This distinguishing feature which sets Perlite apart from other volcanic siliceous rocks is that when heated above 1000ºc, it expands up to 20 times its original size. The expansion is due to the presence of a few percent of combined water in the crude ore.
When processed at proper temperatures, the crude ore pops in a manner similar to popcorn. During the material processing, the combined water vaporizes, creating countless tiny bubbles that account for the amazing light weight and other exceptional properties.
It is expanded and milled carefully in special machinery at Nordisk. Nordisk Perlites machines creates particles into special forms and structures, and those then can create filter cake with countless microscopic channels and give optimum flow rates and clarities for liquids.
