Lightweight Expanded Perlite for Industrial Applications | China Suppliers & Factory

Perlite is an amorphous volcanic glass, known for its high water content, typically formed through the hydration of obsidian. This natural mineral possesses unique properties, particularly its ability to expand significantly when subjected to high temperatures. At our factory in China, we process perlite to enhance its low density, making it a highly sought-after commercial product, When heated to temperatures between 850–900 °C (1,560–1,650 °F), perlite undergoes a dramatic transformation. The water trapped within its structure vaporizes, causing the material to expand to 7–16 times its original volume. The resulting expanded perlite displays a brilliant white color, attributed to the reflectivity of the trapped air bubbles. While unexpanded (raw) perlite has a bulk density of around 1100 kg/m3 (1.1 g/cm3), the typical bulk density of expanded perlite ranges from 30–150 kg/m3 (0.03–0.150 g/cm3), As a leading supplier of perlite in China, we ensure that our customers receive high-quality products that meet various industrial needs, from horticulture to construction.
