    Packing Hydrophobic Fumed Silica is packaged in a 10 kg double-layer paper bag with inner polyethylene liner for moisture protection.
    Storage Hydrophobic Fumed Silica should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from moisture and sources of ignition. Avoid exposure to strong acids, bases, and oxidizing agents. Prevent dust generation and accumulation. Store away from incompatible materials to maintain chemical stability and to avoid potential hazards during handling and storage.
    Shipping Hydrophobic Fumed Silica is shipped in tightly sealed, moisture-resistant bags or drums to prevent contamination and moisture absorption. Containers are clearly labeled and handled as non-hazardous, but dust generation should be minimized. Store and transport in a cool, dry place, away from strong oxidizers and incompatible substances.
