Expanded Perlite is a lightweight, white or light-colored material derived from volcanic glass. It is formed by the rapid cooling of acidic lava, which traps water within its structure, creating a porous and lightweight material with a high thermal insulation capability. The product is non-toxic, odorless, non-flammable, and resistant to acids, alkalis, and high temperatures.

Physical Properties:

• Density: 40-120 kg/m³

• Water Absorption Rate: ≤0.5%

• Thermal Conductivity: ≤0.22 W/M·K

• pH Value: Neutral

• Color: White

• Main Components: SiO2 (75%-80%), Al2O3 (12%-13%), K2O (4%-5%), Na2O (1%-2%), Fe2O3 (1%-3%)

Applications:

• Building Insulation: Used as an ideal insulation material in construction due to its low density and high thermal resistance.

• Agricultural Use: Enhances soil structure, improves drainage, and supports plant growth.

• Water Treatment: Acts as a filter aid and adsorbent in water purification processes.

• Industrial Applications: Utilized as a lightweight aggregate in concrete and as a refractory material in high-temperature environments.

Processing Methods:

• Perlite ore is crushed and screened to obtain particles of various sizes.

• The particles are then heated at temperatures between 800°C to 950°C to expand them into lightweight, porous structures.

• The expanded Perlite can be further processed with binders like cement or water glass to create products such as Perlite blocks or Perlite boards.

Packaging:

• Available in bags ranging from 1kg to 50kg, depending on the application requirements.

Storage:

• Store in a dry place away from direct sunlight. Avoid exposure to moisture to maintain product quality.
