As an accredited Pyromellitic Anhydride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Pyromellitic Anhydride is packed in a 25 kg fiber drum with a sealed polyethylene liner, clearly labeled with safety information. |
| Shipping | Pyromellitic Anhydride should be shipped in tightly sealed containers, protected from moisture, and stored in a cool, dry, well-ventilated area. It is classified as a hazardous material and must be labeled appropriately. Transport according to relevant regulations (e.g., DOT, IMDG, IATA) and avoid contact with incompatible substances such as strong bases and water. |
| Storage | Pyromellitic anhydride should be stored in a tightly sealed container in a cool, dry, well-ventilated area, away from moisture, heat, and incompatible substances such as strong bases and oxidizing agents. Keep container tightly closed when not in use and protect from humidity, as pyromellitic anhydride is hygroscopic and can hydrolyze to form pyromellitic acid upon exposure to water or moisture. |
