Perlite is a lightweight, porous, and thermally insulating non-metallic material. After high-temperature expansion treatment, it exhibits characteristics such as low density, good air permeability, high water absorption, stable chemical properties, fire resistance, sound insulation, and environmental friendliness. It is widely used in building insulation, horticultural planting substrates, flower seedling cultivation, succulent cultivation, and soil improvement. It is also suitable for industrial filtration, sound absorption and noise reduction, fireproofing fillers, and pipe insulation. It can effectively improve soil structure, enhance water and fertilizer retention capacity, reduce building energy consumption, and meet the needs of various scenarios including engineering construction, horticulture, environmental protection, and industrial applications.
