Product Description
Expanded Perlite
In order to make the familiar perlite, we need to mine the gray to Black Obsidian rock, crush it into smaller pieces, and then heat it to a very high temperature. Once the temperature reaches 850-900 ℃, perlite will become soft. Water trapped in the rock evaporates and tries to escape, swelling the rock to more than 10 times its original volume, and turning the color or perlite white. It's very similar to popcorn.

The resulting expanded perlite is a lightweight material filled with tiny air pockets. It is clean, sterile and resistant to compaction. The outer pocket absorbs moisture and prevents it from entering the center of the perlite block.

Expanded perlite has the properties of sound absorption, low moisture absorption and strong frost resistance, so it is widely used as the heat preservation and sound insulation materials for buildings, as well as the materials for agricultural soil improvement and increasing the capacity of moisture preservation.
In addition, it can also be used as auxiliary materials in industrial casting, brewing, filtration, washing and other processes.
Expanded perlite can be added to a soilless mixture to improve drainage and aeration, providing more oxygen to the roots of plants. It is also added to the garden as a soil additive to improve the soil structure. Perlite also helps to reduce the compaction of clay in the soil.
Perlite has been used as aggregate in lightweight thermal insulation concrete, and as loose filling thermal insulation material for concrete blocks, hollow walls and residential buildings. It can also be used in various special applications, such as fire spray, chimney filler, gap floor, acoustic spray, etc.
Perlite filter aids are widely used in water and wastewater treatment, food processing, industrial oil and solvent recovery, purification of chemicals, resins, polymers, waxes, oils, adhesives, paints and more due to it low density, availability, performance, economy and environmental footprint.
As a thermal insulation material of Perlite is widely used in iron and steel and casting industry. It is used as a compound of ladle sprue, hot sprue and riser in the form of heat prevention and insulation, such as buffer, for the manufacture of molding sand and refractory brick.
