Hybrid polyolefin composites based on polypropylene and polyethylene have attracted increasing attentionbecause they combine low density, melt processability, chemical resistance, recyclability, and tunable mechanical performance.However, the structural formation of PP/PE systems remains complex because PP and PE are generallyimmiscible, and their final properties are controlled by phase separation, crystallization sequence, interfacial adhesion,and processing-induced morphology. This study investigates the structural formation mechanisms of PP/PE-based hybridcomposites containing ethylene-vinyl acetate, dioctyl terephthalate plasticizer, recycled rubber, ultra-high molecular weightpolyethylene, and a maleic-anhydride-functional compatibilizer. Six formulations were designed, including HDPE-rich,PP-rich, UHMWPE/HDPE, PVC-reference, PP/UHMWPE, and PP/rubber-rich compositions. Melt blending and extrusionwere used as the main processing route, followed by compression molding. Differential scanning calorimetry, X-raydiffraction, SEM/TEM microscopy, FTIR spectroscopy, rheological analysis, and mechanical testing were used to clarifycrystallization kinetics, phase morphology, interphase formation, and structure-property relationships. The results indicatethat PE-rich systems are governed by high lamellar crystallinity and ductile deformation, whereas PP-rich systemsexhibit higher stiffness but lower impact resistance. The PP/UHMWPE/EVA/rubber hybrid formulation provides the mostbalanced performance trend because UHMWPE domains act as heterogeneous nucleation sites and load-bearing microphases,while EVA and compatibilizer improve interfacial stress transfer. Avrami-based kinetic analysis suggests thatcompatibilization changes nucleation from predominantly homogeneous to heterogeneous behavior, reduces spherulitesize, and increases interphase continuity. The study demonstrates that controlled phase morphology and crystallizationsequence are decisive for optimizing PP/PE hybrid composites for engineering applications.
