| Abstract: | The high-density polyethylene, thermoplastic widely-used in the production of industrial domestic utilities, was collected
in two situations: virgin high-density polyethylene (JV 060) and post-consumption high-density polyethylene (with features
of low-density polyethylene). After collecting the samples, they were submitted to natural aging with the quantification of
the incident solar radiation for 180 days. The samples were characterized by melt flow index, differential scanning calorimetry,
tensile strength, rupture load, elongation at break and infrared. The results showed that after 180 days of exposure the virgin
high-density polyethylene presented physical properties similar to the post-consumption polyethylene.
