Perlite is a type of naturally occurring siliceous volcanic rock with a pearly luster formed by the cooling of molten lava. When it is heated to a suitable temperature, it expands 4–20 times of its original volume. This expansion is due to the presence of water in perlite, which when heated, gets vaporized to form tiny bubbles, thereby providing excellent insulation, lightweight, and durability properties. Hence, perlite finds application in construction, horticulture & agriculture, industrial, pharmaceuticals, food products, personal care products, and water treatment, among others. MarketsandMarkets projects that the perlite market , in terms of value, will grow from USD 1.51 Billion in 2017 to USD 2.20 Billion by 2022, at a compound annual growth rate (CAGR) of 7.78%. The increase in demand for perlite from the construction and agriculture & horticulture sectors drives the growth of the perlite market. Know More: https://www.marketsandmarkets.com/pdfdownload...
