As an accredited PBTCA factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | PBTCA is typically packaged in 250 kg net weight blue or white plastic drums, sealed for safe transportation and storage. |
| Shipping | PBTCA is typically shipped in 250 kg plastic drums or 1250 kg Intermediate Bulk Containers (IBCs). It should be stored tightly sealed in a cool, dry, well-ventilated area, away from strong oxidizing agents. During shipping, the containers must be protected from damage, direct sunlight, and extreme temperatures to ensure safety and stability. |
| Storage | PBTCA (2-Phosphonobutane-1,2,4-tricarboxylic acid) should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances such as strong oxidizing agents. Containers must be tightly sealed to prevent contamination and moisture absorption. Store in corrosion-resistant packaging and clearly labeled containers. Avoid storing near food or drinking water sources to prevent accidental contamination. |
