✦ Synopsis
An experimental study of mixing silica, carbon black, and talc into elastomers in an internal mixer with intermeshing and traditional separated/tangential double-flighted rotors is described. The dispersion in the compound was characterized by measuring the agglomerate size of filler at various mixing times by a scanning electron microscope and image analysis. The distributive mixing was investigated by measuring the incorporation time by a flow visualization technique. The viscosities of compounds were measured in a pressurized rotational viscometer. The intermeshing rotors were found to provide more effective dispersive mixing and their compounds possessed lower viscosities.
