Impact of Storage Condition Factors Influencing Aging of Unvulcanized Natural Rubber Compound, Based on Fatigue Life of Compound, Using Taguchi Method

In this study four relevant factors, temperature, time, humidity and storage atmosphere were selected and the effect of each factor on aging of unvulcanized NR compound were studied at three different levels, based on measuring the ozone resistant and fatigue life time of rubber blends to monitor the extent of degradation. The optimal combination of mentioned factors was determined based on Taguchi protocol, and maximum fatigue life was obtained. Taguchi experimental design reduces cost and improves quality. The result of this work can be useful for rubber industries who storage their final compounds more than one day in the production lines.
