Polyether L-64 (Pluronic L64 / Poloxamer 184) is a non-ionic high-molecular surfactant with certain hygroscopicity. Therefore, moisture-proof sealing is the core point of its storage management. The product should be packaged in clean, dry plastic drums or composite intermediate bulk containers (IBC totes). After opening and use, the container must be immediately re-sealed tightly to prevent moisture from entering and causing product deterioration.
The storage environment should be away from heat sources, sparks, open flames, and direct sunlight. It is recommended to maintain storage temperature within the room temperature range (usually 5°C~35°C), avoiding extreme low or high temperatures. Extreme low temperatures may cause increased viscosity or even solidification, while extreme high temperatures may accelerate oxidation or color changes. At the same time, it should be stored separately from incompatible substances such as strong oxidizers, strong acids, and strong bases to prevent cross-contamination.
Regarding shelf life, according to product data from Guoli Chemical, this product has a stable shelf life under normal temperature and sealed conditions. Generally, for unopened Polyether L-64 stored under recommended conditions, the shelf life can reach 24 months from the date of production (specifically subject to the product's COA or outer packaging label). It is recommended to follow the first-in-first-out principle and regularly inspect the appearance of inventory products.

It is recommended to establish an inventory management system and follow the "First In, First Out" (FIFO) principle. Before each use, quickly visually inspect the appearance of the product. Under normal conditions, it should be a colorless to light yellow transparent liquid. If any abnormalities such as turbidity, stratification, or significant color deepening occur, stop use and perform quality verification. Use clean and dry tools when taking materials to avoid introducing impurities or moisture into the container.
