Used primarily for drying gases and liquids, they effectively remove water molecules due to their uniform pore size. Commonly applied in the petrochemical industry to purify natural gas and refine petroleum products. In laboratories, they are essential for maintaining anhydrous conditions during sensitive reactions, including as packing material in gas and liquid chromatography columns (20-40 mesh). They also play a critical role in the packaging industry to protect moisture-sensitive products, such as electronics and pharmaceuticals. Additionally, they are utilized in air brake systems for heavy vehicles to prevent freezing and corrosion caused by moisture.
