A comparative analysis of the effect of new complex fillers of natural origin on the process of thermal aging of high-pressure polyethylene is carried out. During the research, it was found that the studied fillers have a stabilizing effect, inhibiting the processes of thermal oxidation of high-pressure polyethylene. The stabilizing effect of fillers is due to the presence in their composition of metal oxides capable of chemical interaction with oxygen-containing groups in oxidized polyethylene. It has been established that the carbon-mineral filler has a higher thermostabilizing effect than the carbon-silicon filler from carbonized rice husk.
