Environmental Factors on Aging of nitrile Butadiene Rubber(NBR)A Review
Nitrile rubber(NBR)is widely used due to its excellent properties,but it is prone to aging during storage and use.This article mainly summarizes the external factors that affect the aging process of nBR,including the aging of nBR in liquid and non liquid environments(thermal oxidative aging,ozone aging,stress aging,radiation aging,etc.).The focus of this study is on the physical and mechanical performance testing of nBR.The coupling effect of various factors discussed in this article is an important direction for future research on nBR aging,and subsequent studies should also pay attention to microscopic analysis.
