Chemical stress relaxation of ethylene-propylene copolymer rubber by heat and radiation

In an attempt to shorten the evaluation time for the deterioration under various conditions caused by chemical reactions, we tried to extend the time-temperature superposition principle for the stress relaxation of rubber. In the case of deterioration by radiation instead of by heat, a time-dose rat...

Summary:In an attempt to shorten the evaluation time for the deterioration under various conditions caused by chemical reactions, we tried to extend the time-temperature superposition principle for the stress relaxation of rubber. In the case of deterioration by radiation instead of by heat, a time-dose rate reduction is proposed and the master curves obtained for chemical-stress relaxation of rubber. A new method which contains a numerical analysis of stress decay curves is proposed to obtain the rate of crosslinking and scission under irradiation for already crosslinked samples.
