Improving the impact strength of recycled HIPS by increasing the rubberphase proportion and studying mechanical properties

The use of post-consumer plastics in the development of polymer products and the reduction of theenvironmental effects of plastic waste have attracted the attention of industrialists in this field.However, it is of great importance to employ a suitable strategy to improve the mechanical propertiesand impact strength, considering the final performance of the recycled polymer. This work focuseson enhancing the impact strength of r-HIPS (recycled high impact polystyrene) using differentpercentages ( ۱۰, ۲۰, and ۳۰%) of TPE (thermoplastic elastomer), POE ( polyolefin elastomer), andr-SBS (recycled styrene-butadiene-styrene). Blends were prepared through the melt process using atwin screw extruder and the final properties of the prepared blends were studied. The sample withstyrene-based TPE showed a higher increase in impact strength due to better compatibility andinteraction with the polymer matrix.
