520			_aSkim rubber samples from four processing units were analysed for raw rubber properties. Mplecular breakdown characteristics were studied using a torque rheometer. Both skim crepe and skim block were employed for the studies. Skim rubber showed higher level of inconsistency in raw rubber properties, except for Wallace plasticity. Plasticity of skim rubber was found to be the major factor influencing energy consumption during initial breakdown. The rate of breakdown of skim blocks was higher than that of skim crepe. Plasticity retention index was found to be inversely related to the initial rate of breakdown. The effect of peptiser was found to be less in skim rubber compared to ISNR 5.
