  • Patent number: 6132876
    Abstract: Carbon black pellets which can be produced by the addition of wax during dry granulation of carbon black powder. The carbon black pellets are distinguished by a pellet hardness of at least 0.15 N with a wax content of less than 10 wt. %, based on the total weight of the carbon black pellets.

  • Patent number: 6056933
    Abstract: Inversion carbon blacks and a method for their manufacture and disclosed. The inversion carbon blacks have a smaller rolling resistance with identical or improved wet sliding behavior. The particle size distribution contains a smaller proportion of particles with large diameters. This leads to an improved abrasion behavior of rubber compounds which were prepared using these carbon blacks. The inversion carbon blacks can be manufactured in conventional carbon black reactors by controlling the combustion in the combustion chamber in such a manner that carbon black nuclei form, which are immediately brought into contact with the carbon black raw material. The carbon blacks present a lower proportion of larger particles if the additions of combustion air and carbon black raw material are increased in an appropriate manner.
