Morris M.D., . Contribution of storage hardening to plasticity retention index test for natural rubber. pp. 96-104. ISSN 0127-7065
Abstract
Two experiments were designed to investigate the influence of natural or storage hardening on Plasticity Retention Index (PRI) test results. The first experiment involved ageing of PRI test-pieces under vacuum and the second made use of sequential hardening and ageing of the rubber. Results from both experiments showed that storage hardening had a marked effect on PRI test results even for natural rubber samples which were not freshly prepared. Quantitative estimates of the contribution of hardening to the PRI test were correlated with accelerated storage hardening test results. The correlation indicated that approximately half of the total potential of a rubber sample for storage hardening occurs during the PRI ageing treatment.
