"Isfahan Perlite, the first producer of perlite soil in Iran"
Each grain of perlite has the power to Growth
Perlite is a natural mineral that is widely used in various industries, especially in agriculture, construction, and the chemical industry. Due to its unique properties, such as being lightweight, thermal and sound insulation, and moisture absorption capability, it has gained significant popularity
Perlite applications
? What is perlite and why should we use it
Perlite is a volcanic glass rock composed of aluminum silicate that contains magmatic water within its structure due to volcanic activity. Its unique characteristic is that, when exposed to high temperatures (up to 1200°C), it rapidly expands, and due to thermal shock, its volume increases by 4 to 20 times, depending on the original composition of the rock. This process transforms perlite into fine, bubble-like glass granules, making it an extremely lightweight material (approximately 75 to 150 kg per cubic meter)
Perlite applications in the construction industry
Perlite is used in the construction industry for producing lightweight and insulating blocks, facade and flooring stones, as well as insulating and fire-resistant composites. Perlite blocks, made by combining cement and perlite, are manufactured in both pressed and cast forms, either solid or hollow, offering excellent sound and thermal insulation properties. Perlite facade stone, first patented by Mr. Habibollah Jamshidi and his colleagues, features low density, thermal and sound insulation, and high efficiency for rooftop applications. Additionally, the perlite-based insulating and fire-resistant composite, developed after seven years of research, prevents sound and heat transfer, reduces energy consumption, lightens the building structure, enhances earthquake resistance, and enables fast, water-free wall construction

Application of perlite in agriculture
Expanded perlite, with varying particle sizes and densities, has widespread applications in agriculture, particularly in greenhouse farming and soil amendment. The density of perlite plays a crucial role in pricing, water absorption, and quality control, as inconsistencies can create issues for farmers. Impurities can also reduce quality and increase costs. Standardized packaging, especially in 100-liter bags, helps preserve quality and prevent the transfer of pests and diseases. Additionally, the uniformity of perlite granulation is of great importance, as variations in particle size can have adverse effects on its performance
