Abstract
Becton Dickinson company which makes and sells syringes needs to expand the shelf-life of a specific product. A brief evaluation of this statement conducts to the study of the impact of ozone on the rubber part of the syringe tip cap which is considered as the most prone to degradation. The formulation of the elastomer makes its susceptibility to ozone degradation high. As a result, a visual, material, and functional characterization is needed to estimate the impacts of ozone. Some theoretical elements were confirmed such as the impact of stress on the rubber, but others remain unclear like the impact on the mechanical properties. Thus, this thesis led to a greater understanding of ozone impact and enlighten further questions and analysis.Description
