| Packing | Polytetramethylene Glycol is packaged in 200 kg blue steel drums, featuring secure seal lids and clear product labeling for identification. |
| Container Loading (20′ FCL) | Polytetramethylene Glycol is loaded in 20′ FCL containers, typically in drums or IBCs, maximizing capacity and ensuring safe transport. |
| Shipping | Polytetramethylene Glycol (PTMG) is typically shipped in steel drums, intermediate bulk containers (IBCs), or tank trucks, depending on volume. Containers must be tightly sealed and stored in a cool, dry place, away from heat and oxidizing agents. Shipping must comply with local regulations regarding safe handling and labeling of chemicals. |
| Storage | Polytetramethylene Glycol (PTMG) should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and moisture. It should be kept away from strong oxidizing agents. Avoid freezing and contamination by ensuring containers are clean and clearly labeled. Follow local regulations and the Safety Data Sheet (SDS) for specific storage requirements. |
| Shelf Life | Polytetramethylene Glycol generally has a shelf life of 2 years when stored in tightly closed containers under cool, dry conditions. |
