As an accredited Precipitated Silica factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging for Precipitated Silica is a 25 kg multi-layer kraft paper bag with an inner polyethylene liner for moisture protection. |
| Container Loading (20′ FCL) | Precipitated Silica is loaded into 20′ FCL containers, typically packed in 10-20 kg bags, totaling around 16-18 metric tons. |
| Shipping | Precipitated Silica is typically shipped in multi-layer kraft paper bags, polyethylene-lined bags, or bulk bags, each sealed to prevent moisture absorption. It should be transported in dry, well-ventilated containers, away from direct sunlight, heat sources, and incompatible substances. Proper labeling and handling precautions ensure safe delivery and compliance with regulatory standards. |
| Storage | Precipitated silica should be stored in a cool, dry, well-ventilated area within tightly sealed containers to prevent moisture absorption and contamination. Keep away from sources of water, strong acids, and oxidizing agents. Avoid generating dust during handling. Ensure storage conditions are free from direct sunlight and heat sources. Appropriate labeling and segregation from incompatible materials are recommended for safety. |
| Shelf Life | Precipitated Silica typically has a shelf life of 2 years if stored in sealed, dry, and cool conditions, avoiding moisture exposure. |
