                Application:

                1. Horticultural Applications

                In horticultural applications, perlite is used throughout the world as a componet of soilless growing mixed where it provides aeration and optimum moisture retention for superior plant growth. Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and for peletizing seed.

                2. Construction applications

                Perlite is widely used as a loose fill insulation in masonry construction. Other construction applications include chimney linings, under-floor insulation, gypsum boards, paint texturing, ceiling tiles, and roof insulation boards etc.

                3. Industrial Application

                Ranging from high performance fillers for plastics to cements for petroleum,water and geothermal wells
