The Mooney viscosity of raw natural rubber

Abstract

Non-standard Mooney test parameters have been derived for a range of raw natural rubber grades in an attempt to obtain information other than a simple assessment of viscosity. Increasing the pre-heat time to 5 tnin and observing the torque-time relation over 1-4 min give readings which prove characteristics of the source materials used in the production of the sample and can distinguish therefore between samples of latex grade (e.g. SMR L) and field coagulum grade (e.g. SMR 10) rubbers.
