Storage requirements for soft and hard films mainly include the following aspects:
Temperature control: Soft and hard films should be stored in an environment with suitable temperature. The ideal storage temperature range is 5°C to 25°C, avoiding high temperature and direct sunlight to prevent rubber aging or deformation.
Humidity control: The relative humidity of the storage environment should be less than 70%, avoiding quality problems caused by excessive humidity or dryness. In some cases, such as storing polyurethane products, the humidity even needs to be lower than 65%.
Light protection: Avoid sunlight and strong ultraviolet rays and artificial light. You can use anti-ultraviolet packaging bags for protection, or paint the windows of the storage room with red or orange paint.
Radiation protection: Avoid contact with ionizing radiation sources, such as X-rays, gamma rays, etc., which may damage the molecular structure of rubber and affect performance.
Oxygen and ozone protection: Avoid exposure to circulating air to reduce the occurrence of oxidation reactions. Equipment that may produce ozone, such as mercury lamps, high-voltage electrical appliances, etc., should be avoided in the storage room.
Avoid contact with harmful substances: Avoid contact with solvents, oils or other semi-solid materials, which may react chemically with rubber and cause performance degradation or damage.
Packing requirements: Use materials that will not damage rubber, such as paper or polyethylene. The packaging should be tight to prevent dust, moisture and other impurities from entering.
