Thermoplastic elastomers (TPEs) are materials possessing a unique two-phase structure that combines the elasticity of rubbers with the processability of thermoplastics. Today, TPEs produced by dynamic vulcanization (thermoplastic vulcanizates, TPVs), which demonstrate superior performance characteristics, are of particular importance. The aim of this work was to create dynamically vulcanized TPEs based on nitrile butadiene rubber (NBR-40 AMN) and polyvinylidene fluoride (PVDF) containing a peroxide curing system, as well as to study the influence of the peroxide system concentration on the structure and properties of the resulting materials. The microstructure of the obtained materials was studied using FTIR spectroscopy and differential scanning calorimetry. It has been shown that an increase in the degree of vulcanization of the elastomeric phase leads to an improvement in the complex of operational characteristics: tensile strength, elongation at break, thermal stability, and resistance to aggressive media. The materials demonstrate excellent resistance to water, oil, and petroleum, as well as good resistance to gasoline. Samples with a curing agent content of 0.75 phr possess the best characteristics and the target morphology, where the thermoplastic forms a continuous matrix and the cross-linked elastomer is dispersed within it as particles. For these samples, resistance to thermal aging and recyclability were additionally determined. It was found that the change in key performance characteristics after recycling does not exceed 10%. The obtained materials meet the requirements for oil- and fuel-resistant compositions and may be of interest for use in the automotive, oil, and gas industries. The use of domestic raw materials for their production (nitrile butadiene rubbers are produced by PJSC "SIBUR Holding," and PVDF is produced by JSC "GaloPolymer") ensures the import substitution potential of the development.
