The improvement of thermal and structural properties of PP and HDPE is very important for aging processes. For this purpose, powdered waste urea–formaldehyde was added to PP and HDPE at 5 wt%, 10 wt%, 20 wt% and 30 wt% ratios. The thermal, structural and morphological properties of the produced samples were observed by using thermogravimetric differential thermal analyser, oxygen induction time tests, fourier transform infrared spectrophotometry, X-ray diffractometer and scanning electron microscopy. By the results of the relevant study, the thermal and oxidative stability of the composites was improved by the incorporation of WUF into the polymer matrices. In conclusion, powdered urea–formaldehyde can be a cost-effective and good filler for PP and HDPE.
