Abstract
A method for producing a masterbatch includes feeding (e.g., continuously feeding) a first composition containing an elastomeric latex (e.g., a natural rubber latex) to a coagulation chamber; and feeding (e.g., continuously feeding) a second composition containing a particulate filler (e.g., carbon black) to the coagulation chamber. The carbon black is fed directly from a sonication chamber to the coagulation chamber and/or a sonication device facilitates ultrasonic mixing within the coagulation chamber. The first composition and the second composition are mixed in the coagulation chamber to form the masterbatch. The second composition may be fed to the coagulation chamber at a pressure of at least about 300 psig and/or a velocity of at least about 100 feet per second. The masterbatch may be dry mixed with an additional elastomer to form an elastomeric composite blend.
