When the perlite ore is heated at approximately 850⁰-900⁰C it expands up to 20 times its original volume, unlike many other volcanic glasses, making it perfect for use as perlite insulation. This expansion is caused by water that has been trapped within the ore (approximately 4% water content is trapped within the perlite ore) and the water ...

Perlite is a naturally occurring siliceous volcanic rock containing two to six per cent combined water. When the crude rock is crushed and heated above 1600° F ( 871° C), the combined water vaporizes and the perlite expands four to twenty times its original volume. This expansion process creates countless cells in the glassy particles, which ...

Perlite expansion is a fairly simple process: take raw ore, add heat, and the material expands to the finished product. However, the starting material known commonly as feedstock can weigh heavily on the finished good. If the PSD of your starting product is large, then your finished product will be, too.
