Buy low price 48 INR/kg Expanded perlite. Expanded perlite is perlite that has been subjected to high temperatures, causing it to expand and become a lightweight, white, granular material with a myriad of internal air pockets. This expansion occurs due to the water content within the raw perlite ore vaporizing and causing the particles to "pop" or expand.
The process of expanding perlite involves heating the raw perlite ore to around 1600°F (870°C) or more. The sudden and extreme heat causes the trapped water molecules to turn into steam, creating a tremendous increase in volume. The resulting expanded perlite is then cooled and screened into different particle sizes for various applications.
Here are some key characteristics and uses of expanded perlite:
Lightweight: Expanded perlite is extremely lightweight due to its porous structure, making it an excellent choice for applications where weight is a concern, such as in lightweight concrete and insulation materials.
Insulating Properties: The air pockets within expanded perlite make it an effective insulator. It is used in the construction industry as an insulating material in masonry mixes, plasters, and roof insulation boards.
Horticulture: Expanded perlite is widely used in gardening and horticulture. It is added to soil mixes to improve aeration, drainage, and moisture retention. It is a popular component in potting mixes for container gardening and seed starting.
Filtering: Due to its porous nature, expanded perlite is used in various filtration applications. It is employed in the filtration of liquids, such as in the food and beverage industry for filtering beer and wine.
Construction: In construction, expanded perlite is utilized in lightweight concrete and plaster formulations. Its low density and insulating properties make it suitable for applications where weight and thermal performance are critical.
Industrial Applications: Expanded perlite finds applications in a range of industrial processes, including cryogenic insulation, as a filler in plastics and rubber, and in the production of fire-resistant materials.
The versatility of expanded perlite makes it a valuable material in multiple industries, contributing to its widespread use in various applications.
