As an accredited Hindered Amine Light Stabilizers factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Hindered Amine Light Stabilizers are packed in 25 kg net weight fiber drums lined with polyethylene bags for moisture protection. |
| Container Loading (20′ FCL) | Container Loading (20′ FCL) for Hindered Amine Light Stabilizers: Typically loaded with 8–10 metric tons securely packed in drums or bags, maximizing safety. |
| Shipping | Hindered Amine Light Stabilizers (HALS) are shipped in tightly sealed, moisture-resistant containers to prevent contamination and degradation. During transit, they should be protected from direct sunlight and extremes of temperature. Standard shipping methods include drums or cartons, with clear labeling in accordance to local chemical handling regulations for safety and compliance. |
| Storage | Hindered Amine Light Stabilizers (HALS) should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from direct sunlight, heat, and sources of ignition. Protect from moisture and incompatible materials such as strong acids or oxidizers. Follow all safety protocols and use appropriate labeling to ensure safe identification and handling in storage areas. |
| Shelf Life | Hindered Amine Light Stabilizers typically have a shelf life of 2 to 3 years when stored in cool, dry, and sealed conditions. |
