Mixing of Rubber Compounds - Carl Hanser Verlag

74 3 Mixing Characteristics of Polymers in an Internal Mixer The high viscosity of NR allows to “overfill” the mixer to a certain level. It means that even when the ram is still about 10 to 25 mm away from its end position, an effective mixing at the ram bottom takes place. Figure 3.2 also shows a typical low viscous NR mixing procedure.
