The Benefits of Perlite as Insulation. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular internal structure — essentially clusters of microscopic glass bubbles. This physical transformation makes expanded perlite an extremely efficient, low density insulator.sp.info Explore furtherWhat is Perlite Insulation?

How do you pressurize expanded perlite?

Expanded perlite is pressurized with nitrogen in a tank truck and drawn into the annular space by a combination of vacuum and pressure. For small vessels, where vacuum transfer is not practical, direct conveying of dry perlite by means other than vacuum, under strictly controlled conditions, produces satisfactory results.See all results for this questionsp.info Does perlite need to be dry for evacuation?Perlite for evacuated service must be dry. The normal moisture limit is 0.1 percent by weight. Moisture in the perlite greatly increases the pumpdown time necessary to achieve the low vacuum required.
