PIXE, micro-PIXE and RBS analysis of thermal aged rubber material: On the additives behaviour versus aging time

PIXE, micro-PIXE and RBS techniques were employed to monitor the behaviour of additives in formulated industrial rubber material as affected by thermal aging at 152 °C in oxidative ambient for a period of time ranging between 0 to 39 weeks. It was found that, with aging time, the rubber looses gradually some of its additives by surface segregation followed by thermal destruction of the segregated species. The comparison of the variation in the relative concentrations of additives and the variation in the mechanical properties as aging time increases can highlight some aspects related to the aging process of the rubber material itself.
