A Preliminary Study of Some Methods for Following the Accelerated Aging and Life Prediction of Rubbers
Abstract
Forty three rubber samples aged at temperatures between 70 C and 150 C for periods up to three hundred days were investigated using hardness tests, dynamic mechanical analysis and pyrolysis-gas chromatography-mass spectrometry to determine if these techniques might be useful in monitoring the aging of the samples. The samples were formulated and aged at ARE Holton Heath and included twenty seven acrylonitrile-butadiene rubber samples, twelve polychloroprene rubber samples, and four polyisoprene rubber samples. All three techniques were capable of monitoring changes in the rubbers which correlated with the time and temperature of exposure of the samples. However, successful application of these techniques to the quantitative prediction of lifetime of elastomers from accelerated tests will require further experimentation. Canada.
