CONSUMPTION AND USES 
Consumption of expanded perlite in the United States reached a record level
of 421,000 tons in 1972. The percent disposition by end use is shown in table
3. As in 1971, filter aid, plaster aggregate, concrete aggregate, and insulation
board (included with "Other" uses) were the principal domestic uses of expanded
perlite. Compared with that of 1971, consumption of expanded perlite in filter
aids, plaster aggregate, and low-temperature insulation each increased 2%
in 1972 while use of expanded perlite in concrete aggregate decreased 2%.
Use of expanded perlite in horticultural aggregates was 3% in 1972—
the same as in 1971. "Other uses" totaled 57% compared with 60% in 1971 and
included primarily insulation board, fillers, 
formed products, and smaller amounts of paint additives, texturing granules,
charcoal base, refractories, and miscellaneous agricultural products.
