“…In this study, a behavior typical of oxidative degradation was observed: increase in mean tension at maximum force in the initial phase of the process and a downward trend due to the cumulative effect of degradation (8,(10)(11) . The mean tension at maximum force increased until the third reprocessing and tended to decrease from that point onwards.…”

“…The modifications in the catheters' mechanical properties in one single cycle can be explained by the action of the hydrogen peroxide plasma in the initial phase of the oxidative degradation process, in which the chain split and crosslinking formation reactions can occur simultaneously (8,10) . In this case, the rupture of bonds may have prevailed, as the greater mobility and orientation of the chains produced optimal stiffness for the catheters, making them more ductile and flexible.…”
