Description

Additional artificial aging based on Wear-out Approach is applied to ethylene-propylene-diene rubber insulation service used in boiling reactor-type containment for 16 years. The observed aging trend is slower than the one expected from acceleration aging results. Carbonyl formation estimated by infrared spectroscopy supports this result. According to the trajectory of relation between elongation at break and tensile strength, cross-linking seems to be proceeded in service-used samples during the additional aging to mitigate their degradation
