Handling, Storage & Transport of Carbon Black
Handling of Carbon Black
Carbon Black is available in powder and beaded form. The handling systems vary significally depending on the form of carbon black. Carbon Black is mainly delivered in small bags, big bags and bulk trucks.
Powder Carbon Black has a low pour density, which leads to higher transportation costs. Due to its relatively poor flow characteristics, powder Carbon Black is usually packed in bags. Bulk handling, economics, freight, cleanliness or a particular required property may mandate the use of a beaded black. Pelletized Carbon Black is much easier to handle due to significantly better flow and conveying properties.
When using beaded blacks, wetting/premix times should be extended as much as possible to ensure that the beads have been broken down. A compounder can anticipate dispersion to require more work when using a beaded black. However, this additional work can be offset by faster incorporation of the beaded black into the vehicle and significant improvements in handling and housekeeping.
Carbon black should be stored in a clean, dry space away from exposure to high temperatures, open flames, and strongly aromatic chemicals.
Carbon Black is not ADR. Rather a flammable solid, or classifiable as self-heating substance as defined by UN Recommendations on the Transport of Dangerous Goods and the International Maritime Dangerous Goods Code.
Commercial Carbon Black is not classified as a hazardous material by the following agencies:
- Brazilian Ministry of Transport – GEIPOT
- Canadian Transport of Dangerous Goods Regulations – TDG
- European Transport of Dangerous Goods Regulations by RAIL – RID, by Road – ADR or on the Rhine – ADN
- International Air Transport Association (IATA) United Nations (no UN number)
- U.S. Department of Transportation Hazardous Materials Regulation DOT, GGVS and GGVE
