To develop the technology of explosive pressing of ultrahigh molecular weight polyethylene (UHMWPE) and its powder composite mixtures with inorganic fillers, the thermomechanical properties of an unfilled polymer and a composite containing 3% coke graphite powder (KGP) after explosive pressing were studied. It was found that explosive pressing with a pressure of 0.25-1.3 gpa provides high heat resistance of UHMWPE and the studied composite (154-156 °C), and the filler restrains the thermal deformation expansion of the polymer, which is associated with increased intermolecular and adhesive interaction at the phase boundary. Thus, the method of explosive pressing can be recommended for industrial processing of UHMWPE and its composite mixture with 3 % KGP.
