contraction and expansion. The insulation level change from the initial condition following each thermal/vibration cycle is illustrated in FIGURE 3. The test results clearly confirm expectations regarding insulation compaction experienced by each material. The perlite insulation level showed a steady decline for a total of 5 mm after 10 cycles.

Perlite - North America -

PRODUCTION PROCESS. Perlite ore: production occurs in two stages; extraction of the crude ore at the mine, then drying & milling. Expanded Unmilled Products: the perlite ore is injected into a naked flame in the base of the expansion tower. The perlite becomes soft enough to be expanded by its internal water which is vaporized.

Expanded Perlite 100L | AUSPERL - Australian Perlite

The expansion process is caused by the presence of water in the crude rock. When perlite ore is rapidly heated to above 850°c this water vaporises and causes the softened rock to expand. Tiny glass-like bubbles are produced which account for the lightweight and exceptional physical properties of expanded perlite.
