This study investigates hydrogenated nitrile butadiene rubber (HNBR) as the research object, using polytetrafluoroethylene (PTFE) combined with different amounts of zinc dimethacrylate (ZDMA) as variables. The behavior of hydrogenated nitrile butadiene rubber was analyzed through mechanical property tests, compression set tests, dynamic mechanical property tests, SEM tests, MTS compression fatigue tests, and supercritical carbon dioxide aging tests, and a comparison of four formulations was conducted. The results show that the mechanical properties of HNBR compounds containing only PTFE did not improve significantly, and performance even slightly decreased under tensile testing. The compression set and compression fatigue performance of HNBR compounds containing ZDMA decreased. The HNBR compound containing both PTFE and ZDMA showed optimal dynamic mechanical properties and performance after supercritical carbon dioxide aging. The experimental findings indicate that hydrogenated nitrile butadiene rubber containing 10 parts of PTFE and 10 parts of ZDMA exhibits superior mechanical properties and resistance to supercritical carbon dioxide aging under the same conditions.
