Perlite--how it works

One of China leading producer of expanded perlite for constuction,industrial and horticulture applications

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.

Rapidly heating perlite ore to temperatures of about 900 degree celsius (1,700。F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn.

The expanded particles that result are actually clusters of minute, lightweight, insulating, glass bubbles. Broken bubbles and surface openings on the particles provide for water and air holing capacity-especially important in horticultural uses.

Sophisticated manufacturing techniques allow the expansion and collection of individual perlite bubbles, which are used as fillers or extenders for a wide variety of products.

Crushed expanded perlite particles present a maze of microscopic pathways that can be used to filter and clean a wide array of liquids, beverages, and pharmaceutical products.
