  • Oxidized Wet Beaded Carbon Black
    Publication number: 20250145834
    Abstract: The present invention relates to a process for the production of oxidized wet beaded carbon black. It has been found that carbon black can be wet beaded and oxidized subsequently. This process allows a better control of the degree of oxidation without damaging the beads. Moreover, the oxidized wet beaded carbon black can be beneficially used in a rubber composition to increase the properties of the resulting rubber product.

  • Method for Controlling the Oxidation of Wet Beaded Carbon Black
    Publication number: 20250034399
    Abstract: The present invention relates to a method for controlling the oxidation of wet beaded carbon black in a screw conveyor. It has surprisingly been found that the motor current used to drive the conveyor screw is an indicator for the destruction of the wet beaded carbon black during the oxidation. The inventive method as well as control device utilize said motor current and adepts the rotational speed of the screw.

  • Pulverulent Acetylene Black Material, Process for Its Production, and Compositions, Manufactured Articles and Uses Thereof
    Publication number: 20240240026
    Abstract: A process is provided for producing a pulverulent acetylene black material including (a) providing an initial acetylene black, (b) densifying the provided initial acetylene black to form a densified acetylene black, and (c) pulverizing the densified acetylene black to form the pulverulent acetylene black material. The pulverulent acetylene black material obtainable by this process exhibits inter alia enhanced dispersibility and yields dispersions that show improved stability over time rendering them useful as conductive or antistatic agent, reinforcing filler and/or coloring agent in compositions for various applications such electrodes and other components of energy storage and/or conversion devices, plastic articles, coatings, paints or inks.
