Polymer materials with low-temperature characteristics must ensure the reliability of machinery, structures and structures when exposed to both external and internal factors capable of destroying the material. Analyzing the scientific and technical literature in the field of materials science, in particular elastomeric materials that can work in various hydrocarbon environments in cold climates, it was decided to continue research aimed at increasing the frost resistance and durability of elastomeric materials resistant to fuel. The paper describes the results of a study of nitrile butadiene rubbers by modification with vulcanization agents and polymer additives in order to improve the complex of operational properties of elastomeric sealing materials. The properties of vulcanizates of standard rubber compounds based on butadiene-nitrile rubbers with different contents of nitrilacrylic acid are investigated. Organic 2di-(2-tretbutylperoxyisopropyl)-benzene peroxide of the Luperox F-40 trademark and a combination of sulfur with an accelerator were selected as vulcanization agents. Their rheological properties are determined depending on the type of vulcanizing agent. The physicomechanical and low-temperature properties of the obtained vulcanizates have been studied. The effect of a type of vulcanizing agent in a rubber compound based on polar rubbers on the low-temperature properties of vulcanizates has been studied. Formulations of rubber compounds based on butadiene-nitrile rubber modified with semi-crystalline and styrene-butylene-styrene block copolymer for increasing low-temperature properties are studied. The physicomechanical properties of the obtained materials have been studied. Formulation and technological solutions are proposed to increase the frost resistance of polymer composite materials based on elastomers operated at low temperatures. Research aimed at developing new methods for modifying elastomeric materials based on BNC will effectively solve the problems of creating multifunctional rubbers for regions with a cold climate.
