Description	Journal: Iop Conference Series: Materials Science and Engineering Operation of elastomeric materials in the extreme climatic conditions of the North is complex and expensive, since not always existing materials can provide the required level of low-temperature characteristics (down to - 60 °C). This leads to failure of machines and mechanisms, equipment downtime, additional costs for repair or replacement of elastomeric parts. This study investigates the features of elastomeric composites operation in cold climates and the results of full-scale tests with simultaneous exposure to naturally low temperatures and hydrocarbon environments in Yakutia (Siberia, Russia). It presents the main principles of creating elastomeric composites for sealing purposes with high frost resistance and examples of recent developments. To obtain elastomeric materials of high frost and oil resistance new rubbers of high frost resistance as Hydrin T6000 epichlorohydrin rubber $(T_{g}$ = - 60 °C), and traditional rubbers (nitrile etc) were used. For elastomer modification we used carbon nanotubes, collagen hydrolysate and polymer mixtures. Different type of developed materials is a double-layer material based on ultra-high-molecular-weight polyethene (UHMWPE) and nitrile-butadiene rubber-based elastomeric composite. The effect of diphenylguanidine on the interaction of UHMWPE with elastomeric composite based on nitrile butadiene rubber and adhesion at the interface was investigated. The operating properties were studied by standard methods and the structure of the obtained materials was studied using electron microscopy.
