The thermal characteristics of the initial UHMWPE and its composites with QGP and MDF, as well as those obtained by explosive pressing (VP), have been investigated. It has been established that explosive pressing leads to hindering the processes of melting and thermal destruction, which may be associated with chemical interaction, the formation of inter- and intramolecular cross-links characteristic of this polymer. UHMWPE and its compositions with 3% CHP after VP have higher melting points of the crystalline phase, thermal oxidation and thermal destruction in comparison with the starting materials of similar composition. In the UHMWPE composition with 10% MDF, no increase in thermal properties after VP was observed, similar to the original fluoroplastic.
