Study on Thermal Oxidative Aging of Nitrile Rubber

Abstract:

This paper studies the changing regularity of hardness and tensile strength, through accelerated aging test of NBR in hot air. The tensile fracture appearance of test samples aging for different time is observed. The results indicate that NBR’s hardness increases firstly and then decreases and finally increases again, tensile strength presents escalating trend and the change of tensile fracture corresponds with polymer fracture mechanism of elastic material.
