Lightweight Aggregate: Perlite is used as a lightweight aggregate in concrete and plaster to reduce the overall weight of structures while maintaining strength.
Insulation Material: Perlite is utilized in insulating materials for walls, roofs, and floors, providing thermal insulation and improving energy efficiency.
Horticulture and Agriculture:
Soil Amendment: Perlite Perlite applications is a popular soil amendment that improves aeration, drainage, and water retention in potting mixes. Its neutral pH and sterile nature make it ideal for growing a variety of plants.
Hydroponics: In hydroponic systems, perlite is commonly used as a growing medium due to its lightweight nature and ability to provide support for plant roots while allowing water and nutrients to reach them.
Filtration and Water Treatment:
Filter Aid: Perlite is used as a filter aid in various industries, such as food and beverage processing, to clarify liquids by removing solid impurities. It is an effective and inert filtration media.
Water Filtration: Perlite is employed in water filtration systems to remove impurities and suspended solids, ensuring cleaner water.
Cryogenic Insulation: Perlite’s low thermal conductivity makes it suitable for cryogenic insulation applications, such as in the storage of liquefied natural gas (LNG).
Fireproofing: Perlite is used in fireproofing materials, such as plasters and coatings, to enhance fire resistance in buildings and industrial structures.
Personal Care and Cosmetics:
Exfoliant in Cosmetics: Perlite is used in cosmetics and personal care products as a gentle exfoliant due to its finely milled texture, helping to remove dead skin cells.
Absorbent Material: Perlite is employed as an absorbent material in industrial cleaning products, such as oil spill cleanup agents, due to its ability to absorb liquids rapidly.
Slag Coagulant: In metallurgical processes, perlite is used as a slag coagulant to facilitate the removal of impurities from molten metal.
High-Temperature Insulation: Perlite’s resistance to high temperatures makes it suitable for insulation in applications like refractories, foundry work, and furnace linings.
Absorbent Bedding: Perlite is used in animal bedding, such as for horses and small animals, due to its absorbent properties and lightweight nature.
Textured Finishes: Perlite is sometimes added to paints and coatings to create textured finishes on walls and ceilings.
