Perlite toxicology and epidemiology – a review
Perlite is a generic name for an amorphous volcanic alumina–silicate rock that expands by a factor of 4–20 when rapidly heated to 1400–1800 °F (760–980 °C). Both the ore and the expanded product have extensive and widespread commercial applications. Limited data on the toxicology of perlite in animal studies indicate that the …

Understanding the Performance Differences Between Expanded Perlite …
The reason perlite insulation is technically referred to as "expanded perlite" is because when it is heated during the manufacturing process (to approximately 1600°F/900°C) the moisture expands, causing it to pop like popcorn at 1600°F. This makes perlite a very low-density material that is light-weight, with low thermal conductivity values.
