The Prediction of Shelf-Storage Life in Rubbers from Accelerated Heat Ageing Tests. Part I. Accelerated Oven Ageing

摘要

Oven ageing experiments in which the mechanical tests are performed at the temperature of ageing have been carried out on Nitrile, Neoprene, and Hypalon rubbers. In all cases the variation of one or more of the mechanical properties with time at a series of temperatures allows predictions to be made of shelf-storage life at ambient temperature. Comparisons drawn between these predictions and the results of actual shelf-storage tests are encouraging. (Author)
