| Sumario: | Recycled polymers offer opportunities for circular material use, yet their mechanical performance is often limited by feedstock variability. This study provides a controlled comparison of neat recycled PVC and WPC (PVC + 20 wt.% wood flour) processed under identical extrusion and compression-molding conditions. Tensile, flexural and hardness tests were conducted according to ASTM standards, and results are reported as mean ± standard deviation (n = 5). The WPC exhibited modest but measurable increases in tensile strength (~12%), flexural strength (~8%), and Shore D hardness (~8.5%), while tensile and flexural moduli remained statistically comparable between the two materials. Flexural modulus exceeded tensile modulus for both materials, consistent with surface-dominated stress distributions in bending. The findings demonstrate that incorporating 20 wt.% wood flour into recycled PVC can enhance selected mechanical properties without compromising stiffness, offering a performance profile consistent with material-substitution pathways in circular-economy strategies. The study also highlights the influence of recycled feedstock variability and identifies the need for future microstructural characterization to confirm the hypothesized deformation and failure mechanisms. |
