Abstract
ISO 2930:2017 specifies a method for determining the plasticity retention index (PRI) of raw natural rubber.
The PRI is a measure of the resistance of raw natural rubber to thermal oxidation. A high resistance to thermal oxidation is shown as a high value of the index. PRI is not an absolute value and cannot give an absolute classification of plasticity number of different natural rubber after oxidation.
