As an accredited Polymaleic Acid factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Polymaleic Acid is packaged in a 25 kg high-density polyethylene (HDPE) drum, securely sealed, and labeled with product details and safety information. |
| Shipping | Polymaleic Acid is typically shipped in polyethylene or fiber drums, or intermediate bulk containers (IBCs), tightly sealed to prevent moisture absorption and contamination. It should be stored and transported in a cool, dry, and well-ventilated area, away from incompatible substances. Proper labeling and compliance with relevant transportation regulations are required. |
| Storage | Polymaleic acid should be stored in tightly sealed containers away from moisture, heat, and direct sunlight. It should be kept in a cool, dry, and well-ventilated area, separate from incompatible substances like strong oxidizers and bases. Storage containers must be labeled properly, and access should be restricted to trained personnel using appropriate protective equipment. |
