The raw rubber such as EPDM and CR were first mas- ticated on the laboratory open two roll mill (XK 160) for ten minutes. The required amount of MgO was incorpo- rated with CR on a two roll mill at first. Zinc oxide, stearic acid and other rubber additives were added sequentially in masticating EPDM rubber. Finally, CR rubber with mag-

The initial mastication of natural rubber (NR) can be performed in an open two-roll rubber mill or in an internal mixer. Repetitive mechanical deformation in the presence of atmospheric oxygen causes a reduction in the MW of the rubber, and it becomes increasingly plastic. At this stage, rubber compounding ingredients can be

The rolls can be heated or cooled as necessary. The rubber is placed on the rolls and mixing is achieved by the shearing action induced at the "nip" between the rolls. Additives are added in carefully weighed quantities during the mixing process. After the mixing operation is complete, the compound is removed from the mill in the form of sheet.
