Expanded perlite aggregate is produced by heating the perlite volcanic rock to its softening temperature. The water in perlite grains is vaporized under heating temperatures of 700–1200 °C, and perlite can be extended to a volume of up to 15–20 times its initial size [11].

Crude perlite expanded for use as a concrete aggregate ranges from 1 mm (plus 16 mesh) to 0.2 mm (plus 100 mesh). Ninety percent of the crude perlite ore expanded for horticultural uses is greater than 841 µm (20 mesh). Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled.

Expanded perlite is also used as an acoustic material. All building materials have sound absorption properties. However, it is customary to call sound-absorbing materials only those with sound absorption coefficient (SAC) at medium frequencies greater than 0.2. The absorption process is based on noise reduction due to the transfer of …

In a unique application of expanded perlite's insulative properties, unopened perlite bags are placed under concrete slabs to provide a thermal break between soil and concrete and mitigate heat loss—of particular benefit to radiant in-floor heating systems. Expanded perlite is dimensionally stable, non-combustible, and will not rot.

Types of perlite. After heating and expansion, horticultural perlite is separated into four different grades based upon the particle size: super coarse, coarse, medium, and fine grade. Super coarse perlite has particles ranging in size between ¼ and 3/32" with a water holding capacity of 19%. Creates the best porosity for drainage and aeration but isn't as …

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.

Ryolex is our brand of expanded perlites we refer to as macroparticles. These coarser particles are produced by heating crushed perlite between 1600 and 1800 F, causing the particles to expand 4 to 20 times due to the vaporizing of water in the rock. This expansion accounts for Ryolex's light weight and other exceptional physical properties.
