Description
Summary:Polypropylene (PP) and its derivatives are widely used to produce molded plastics due to their lightweight and impact resistance. Polyethylene terephthalate (PET) is considered one of the essential engineering polymers for its applications, widely used to manufacture containers for liquids such as water, oil, etc. The compatibility of PP/PET increases the impermeability, thermic and mechanical properties. The present study shows the blend binary of recycling PET as refill into a v-PP matrix extruded in filament analyzing the specific density and XRD. The result XRD pattern exhibited the presence of miscibility of monoclinic α-form phase v-PP/r-PET peaks predominantly attributed to the crystallinity of baseline material. Likewise, crystallinity, and amorphous peaks are attributed to the semi-crystalline phase of r-PET with a triclinic structure. In the impact strength test, all specimens tested showed partial failure on the surface, majorly presenting cracks, and fractures.
