Based on the data for accelerated life and natural storage life of six rubber sealing materials including
EPDM-8101, EPDM-8106, NBR-45713, NBR-5073, FKM-7103 and CR-4103, the accelerated factors were
calculated. The results indicate that excent FKM-7103, the accelerated factors are agree with Van′Hoff factor. The
accelerated factors of aging temperature can be used to predict storage life of rubber sealing materials instead of the accelerated
factors between accelerated life and natural storage life.
