The article considers the issues associated with the elastic and plastic properties of fluoroplastic in the state of delivery and radiation hardened. The statement about the radiation hardening of fluoroplastic improves thermal deformation characteristics is substantiated. The results of kinetic microindentation are studied in comparison with the initial state in the temperature range of 80 - 400 0C. The effect of temperature on the ratio of the work of the elasticity and plasticity forces is analyzed. Particular attention is paid to the elastic properties of fluoroplastic. The assumption is substantiated that it is possible to improve the elastic properties of fluoroplastic by radiation treatment at elevated temperatures, which are typical for high-speed axial piston pumps. On the basis of the study, it was found that the use of radiation hardening treatment of fluoroplastic is promising for increasing the durability of movable seal rings.
