Polyether F-38 (Poloxamer 108) is a nonionic surfactant with good chemical stability. It is stable under normal storage and handling conditions, non-flammable, non-explosive, and is classified as a general chemical product. The key to storage management lies in moisture prevention, contamination control, and temperature regulation to ensure the product maintains optimal performance before use.
This product may solidify or become turbid under low-temperature conditions, which is a normal physical change. Simply raise the material temperature above room temperature and stir evenly to restore its original state, without affecting product quality. Therefore, even if appearance changes occur during winter storage and transportation, there is no need to worry about product failure.
| Storage Element | Specific Requirements |
|---|---|
| Warehouse Environment | Cool, dry, well-ventilated, away from ignition sources, heat sources, and incompatible substances (such as strong oxidizers) |
| Temperature Range | Recommended 5°C – 40°C |
| Packaging Management | Keep containers tightly sealed to prevent moisture and contamination; empty containers must not be repurposed without proper treatment |
| Shelf Life | Under recommended storage conditions, the shelf life of unopened original packaging is typically one year |
| Low-Temperature Treatment | If solidified or turbid, warm up and stir evenly to restore; does not affect quality |
After opening, use as soon as possible. Avoid introducing moisture and impurities when taking material. For long-term storage, it is recommended to immediately seal the container after each use and regularly check packaging integrity. If the product has exceeded its shelf life, perform small-sample performance verification before use to confirm that key indicators (such as hydroxyl value, cloud point, surface activity, etc.) still meet process requirements before deciding whether to continue using.
