Lightweight Expanded Perlite Insulation: Top China Suppliers & Reliable Factory Solutions for Industrial Applications

Perlite is an amorphous volcanic glass with a high water content, primarily formed by the hydration of obsidian. Found naturally, this unique industrial mineral significantly expands when heated to temperatures between 850–900 °C (1,560–1,650 °F). As the water within its structure vaporizes, perlite expands to 7–16 times its original volume, resulting in a strikingly white material due to the reflective trapped bubbles, In its raw state, perlite has a bulk density of around 1100 kg/m3 (1.1 g/cm3), while the expanded version has a much lower density of approximately 30–150 kg/m3 (0.03–0.150 g/cm3). This low-density expanded perlite is commercially valuable, making it a preferred choice among suppliers in various industries, As one of the leading perlite suppliers and manufacturers in China, our factory ensures top-quality perlite products that cater to diverse applications. Whether for horticulture, construction, or insulation, our expanded perlite is ideal for enhancing performance while reducing weight.
