1. Does carbon black have a shelf life?
First of all, the main component of carbon black is C, which has relatively stable chemical properties and generally does not undergo chemical reactions. If it is in a relatively dry, cool, and ventilated environment, the shelf life of carbon black is not limited. Carbon black, however, absorbs moisture until an equilibrium value is reached. If the environmental humidity has a great influence, it will still affect the carbon black.
2. How to save carbon black
Keep away from high-temperature heat sources, avoid putting them together with strong oxidants and volatile substances, keep a well-ventilated, dry environment, and a cool and light-proof environment, and seal the carbon black as much as possible.
