Applications

Perlite is used across a wide range of industrial applications for its light weight, porous structure, chemical stability, thermal insulation, filtration and absorption properties. Its uses span construction and passive fire protection, cryogenic insulation, food and beverage filtration, animal feed production, agriculture, soilless cultivation and foundry operations. It serves as a functional filler in paints, coatings, adhesives, paper, plastics and composites; an absorbent and texture modifier in consumer care and hygiene products; and a liquid retention material in industrial spill control and waste management. Ore selection, expansion, milling and classification produce grades suited to different applications, with properties such as density, particle size distribution, permeability and absorption tailored to specific technical requirements.
