  • Publication number: 20230203255
    Abstract: Methods for producing an uncured masterbatch material from a solution masterbatch that includes an uncured polymer, for example a polydiene such as present in a guayule cement, a diluting liquid and a particulate filler. The solution masterbatch is subjected to resonant acoustic mixing which provides excellent dispersion of the solution components and leads to a masterbatch material having desirable properties. After resonant acoustic mixing, the solution masterbatch can be dried and further processed with other components and a curative to prepare a vulcanized composition.
