This study the effect of alkaline treatment on the tensile properties of LDPE/BSS and LDPE/BSSNaOH composites at various loadings (5–25 phr). The composites were fabricated through a Z-blade mixer and compressed at the temperature of 160oC. The tensile strength increased with filler loading up to 15 phr but decreased at 20 phr due to filler agglomeration. Alkali treatment enhanced filler-matrix adhesion, resulting in higher tensile strength and Young’s modulus for LDPE/BSSNaOH composites. Elongation at break decreased with filler content, indicating improved stiffness but reduced ductility. The findings highlight the role of filler loading and surface treatment in optimizing mechanical performance, offering insights for developing high-performance, sustainable polymer composites.
