| Opis: | The aim of this study is to compare the structure as well as the mechanical and thermomechanical properties of polyethylene stabilized with a petrochemical additive (Irganox 1010) and a sustainable alternative, antioxidant-rich black tea waste leaves (BTW). The influence of both stabilizers was evaluated for samples produced by compression, injection, and rotational molding (CM, INM, and RM). The polymer ma- trix used was low-density polyethylene LDPE SBC 818 I’m Green® (Braskem), modified with 5 wt% BTW and an equiva- lent amount of Irganox 1010 based on the total phenolic con- tent in BTW. Stabilization efficiency was assessed using Fourier transform infrared spectroscopy (FTIR) and calori- metric techniques, including oxidation induction time (OIT) and oxidation onset temperature (OOT), both measured by differential scanning calorimetry (DSC). Additionally, porosity, mechanical performance in static tensile testing, and Vicat softening temperature (VST) were determined to provide a comprehensive comparison of the stabilization systems. |
