The source of the ore for the manufacture of perlite is a naturally occurring siliceous volcanic rock. This is quarried, crushed and screened into closely graded fractions by perlite expanded processing plant.

Perlite Expanded Processing Plant Manufacture

Expanded perlite can be manufactured to weigh from 2 lb/ft3 (32 kg/m3) to 15 lb/ft3 (240 kg/m3) making it especially suitable for use in insulation applications.After processing in perlite expanded processing plant, perlite is used in the manufacture of lightweight perlite concrete, insulating board, insulating plasters, cryogenic insulation, masonry wall insulation and as underfloor insulation.

Perlite is converted into expanded perlite by heating it in a furnace. When quickly heated to above 870oC (1600oF) the crude rock pops in a manner similar to popcorn as the combined water vaporises and creates coutless tiny bubbles in the heat softened glassy particles. It is these tiny glass sealed bubbles which account for the light weight and excellent insulating properties of expanded perlite.
