Handling, Storage & Transport of Carbon Black

The handling of Carbon Black

Carbon Black is available in powder and bead form. Handling systems vary considerably depending on the form of the carbon black.
Carbon Black is mainly supplied in bags, big bags and silos.

Powder carbon black has a low bulk density, resulting in higher transport costs, and is usually bagged due to its relatively poor flow characteristics. Silos, economy, freight, cleanliness or specific requirements, may necessitate the use of a beaded carbon black. Beaded carbon black is much easier to handle due to its much better flow and conveying properties.

When using beaded carbon black, the wetting/pre-mixing times should be extended as much as possible so that bead dissolution is assured. A compounder can expect that dispersion will require more work when using beaded carbon black. This extra work, could be avoided by filling the beads faster into the mixing unit.

Storage

Carbon Black should be stored in a clean and dry place where it is not exposed to high temperatures, open flames and strong aromatic chemicals.

Transport

Carbon Black is not an ADR, either a flammable solid or a self-heating substance under the UN Recommendations on the Transport of Dangerous Goods and the International Maritime Dangerous Goods Code.
