  • Thermally Conductive Polymer Compositions Containing Carbon Black
    Publication number: 20230416585
    Abstract: A composite polymer composition comprising partially crystallized carbon black. The composition exhibits superior thermal transfer properties in plastic formulations. The polymer precursor exhibits excellent rheology when compared to similar compositions comprising traditional carbon blacks. The composite polymers provide for higher loading of more thermally conductive carbon blacks in a variety of composite polymer compositions.
    Type: Application
