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 -like cellular internal structure — essentially clusters of microscopic glass bubbles. This physical transformation makes expanded perlite an extremely efficient, low ...

For some workers, exposure can result in temporary physical irritation, discomfort, impaired visibility, and enhancement of accident potential. However, the most recent health study (1994) of perlite by Dr. Hans Weill of Tulane University concluded that workers exposed to perlite are free of any measurable adverse respiratory effects.

Members of the Perlite Institute work together to learn the most efficient and effective ways to produce market-ready perlite, to build awareness among target industries of perlite's incredible potential, and to research and then communicate the mineral's properties to end-users. Aside from helping to promote the use of perlite on a larger ...

Perlite filter aids provide users with a lightweight material choice. Perlite filter aid grades provide the user with a density advantage from 20 to 50% over other types of filter aids. Perlite filter aid dry density ranges from 100 to 200 kg/m3 (6 to 12 lb/ft3), and the filter cake density range is 100 to 270 kg/m3 (7 to 17 lb/ft3).
