Storage Conditions:

1. Temperature control: EPDP should be stored in a dry, cool, and well ventilated place, avoiding direct sunlight. The ideal storage temperature is usually between 5 ° C and 30 ° C. High temperature may cause polymer decomposition, while low temperature may cause polymer crystallization or become viscous.

2. Humidity control: As EPDP is a hygroscopic material, it should be ensured that the relative humidity of the storage environment is low to prevent the polymer from absorbing moisture. High humidity may cause polymer hydrolysis, affecting its performance.

3. Avoid pollutants: EPDP should be stored in a clean environment to avoid contact with dust, dirt, or other pollutants. These pollutants may affect the performance and appearance of polymers.

4. Packaging and sealing: EPDP should be stored in sealed containers to prevent oxygen, moisture, and other pollutants from entering the air. The selection of containers should take into account the characteristics of the polymer and the storage environment.

5. Avoid mechanical stress: During storage and handling, excessive mechanical stress should be avoided on EPDP, such as compression, collision, or strong vibration. These stresses may cause structural damage or performance degradation of polymers.

6. Fire safety: Although EPDP itself is not a flammable material, it may cause fires at high temperatures or near fire sources. Therefore, it is necessary to ensure that the storage area is away from fire sources and equipped with appropriate fire-fighting facilities.

7. Inventory management: The inventory status of EPDP should be regularly checked to ensure that it is used within its validity period. Expired polymers may experience performance degradation or no longer be suitable for use.

8. Record management: It is recommended to keep detailed records of the storage status of EPDP, including storage date, temperature, humidity, pollutant situation, and other information. These records help track changes in polymer performance and the source of issues.
