Our Products/ AM Expanded Perlite

Perlite Ore when heated to above 870°C (1600°F) , ‘pops’ like popcorn, expanding up to 16 or more times its original volume.

Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original.

AM Expanded Perlite is either un milled (whole pearls) classified according to the pearl size, or lightly milled and classified according to strict particle size distribution.
