| Join own Chris Moran, PHD during his conference about “Influence of stabilizers on property retention of thin wall tubing”
Degradation on the surface of thin wall medical tubing influences bulk mechanical properties more so than in standard test specimens. This study aims to characterize the degradation behavior of tubing with 0.004” wall thickness made from PEBA and TPU, with and without stabilization packages. Tubing is aged under various conditions to elucidate the relative contributions of thermal-oxidation, photo-oxidation, and hydrolysis degradation mechanisms on mechanical performance. Tensile testing and GPC are used to observe degradation over time of stabilized and non-stabilized tubes, and to relate their molecular weight distributions to their mechanical integrity. To calculate the Arrhenius parameters of this system, in which multiple reactions occur with spatial variability, time-temperature superposition is shown to be a superior to the typical approach of using Q10 factors. Compounding stabilizers into PEBA and TPU resins prior to extruding tubing is shown to drastically improve shelf life and resistance to oxidation and UV light. |
