Elastomeric composites based on propylene oxide rubber with a high filling degree (more than 10 phr) of ultrafine polytetrafluoroethylene (UPTFE) were studied. It was shown that with an increase of the fluoropolymer component content, the values of the physical and mechanical properties and frost resistance coefcient decrease. At the same time, the values of oil resistance and “surface” properties of materials, such as wear resistance and friction coefcient were improved up to 50%, 22% and 30% respectively. As shown by tribological testing of rubber containing 50 phr UPTFE, the elastomeric compo-sites operate stably under wear conditions in a wide range of loads and sliding speeds at -25 ° С.
