Rubber, raw natural — Determination of plasticity retention index (PRI)
Preview
Summary
This document 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.
