United Perlite Corporation is continuously searching for new technologies to further improve the quality of its perlite filter aid, insulation, and construction grade, horticulture grade, patching compound, paint filler, and pre-molded products for boilers, geothermal power plants, and oil refineries.

Perlite is not a brand name but a generic term for a naturally occurring siliceous rock. Perlite is distinguishable from other volcanic glasses when heat it to a suitable point, it expands from four to twenty times its original volume.

Industrial applications for perlite are the most diverse, ranging from high performance fillers for plastics to cements for petroleum, water and geothermal wells. Other applications include its use as a filter media for pharmaceuticals, food products, chemicals and water for municipal systems and swimming pools.
