Abstract:
Recycling polymeric waste is a growing strategy to reduce environmental impact and support sustainable material development. Among various polymers, ethylene-vinyl acetate (EVA) and polyvinyl chloride (PVC) wastes are abundant yet challenging to combine due to their chemical and morphological differences. This study investigates the interfacial and morphological behavior of recycled ethylene-vinyl acetate (EVA) and polyvinyl chloride (PVC) composites processed under varying EVA contents (10-30 wt%). Using experimental data from mechanical and physical characterization, the analysis focuses on structural interactions, phase distribution, and the influence of additives on the composite interface. Results indicate that moderate EVA content (20 wt%) optimizes interfacial adhesion and phase dispersion, yielding enhanced flexibility and balanced tensile strength. Excessive EVA loading leads to morphological separation and density reduction due to weak interfacial bonding. The research highlights the morphological control of recycled EVA/PVC systems as a viable route to achieve sustainable, lightweight composites without additional processing.
