NBR’s Storage Life Prediction Based on the Accelerated Life Test

Based on the nitrile rubber accelerated life tests, using the stress relaxation coefficient changes as the aging performance indicators, the relationship between NBR’s stress relaxation and aging time was given ,and also the NBR’s aging dynamic equation was established to predict of the material’s storage life in the normal storage temperature and storage time ,which can be used as reference to predicte NBR’s storage life .
