Pearlite is a glassy rock formed from acidic lava erupted from a volcano, which has been rapidly cooled, and is named for its pearl-like fissure structure. Pearlite ore includes pearlite, obsidian, and pitchstone. The distinction lies in the fact that pearlite has circular arc-shaped cracks formed by condensation, known as the pearlite structure, with a water content of 2~6%; pitchstone has a unique resinous luster, with a water content of 6~10%; and obsidian has a glassy luster and a conchoidal fracture, with a water content generally less than 2%.
Expanded Perlite, after being finely and ultra-finely milled, serves as a filler in rubber and plastic products, paints, inks, synthetic glass, heat-insulating mica, and various mechanical components and equipment. It becomes a lightweight, multi-functional new material through expansion. It features low apparent density, low thermal conductivity, good chemical stability, a wide temperature range of use, low moisture absorption, and is non-toxic, odorless, flame-retardant, and sound-absorbent. It is widely used in various industrial sectors.
Widely used in: concrete aggregates; lightweight, thermal insulation, heat-insulating and sound-absorbing boards; fire-resistant roof materials and fillers, mortars, etc., for high-rise building structures that require fire, frost, seismic, fire, and radiation protection; various industrial equipment and pipeline insulation materials; inner walls for deep-freeze and cold storage facilities; inner walls for storage and transportation of low-boiling-point liquids and gases.
