The paper presents the results of a study of the influence of various concentrations of furnace low-level carbon black of the P-803 brand on the physical, mechanical and temperature properties of elastomers based on frost-resistant butadiene rubber of the SKD-V brand. With an increase in the carbon black content in the elastomeric matrix, the relative elongation, conditional tensile strength, and residual deformation compression increase to the optimal concentration. According to the results of the study, it can be concluded that the optimal content of technical carbon P-803 is in the range from 90 to 130 wt.h. in a rubber compound based on SKD-V rubber.

The effect of electrically conductive carbon black CH600 produced by Omsk Karbon Group on the electrical conductivity and mechanical properties of composite materials based on linear low-density polyethylene has been studied. It has been established that the filler provides high electrical conductivity of the studied composites in the range of 10–20 wt.%, significantly increases their modulus of elasticity and tensile strength, but at the same time reduces the relative elongation at break. Despite the ambiguous effect of the studied filler on the mechanical characteristics of composite materials, carbon black CH600 proved to be a highly efficient and promising filler for creating electrically conductive polymer composite materials based on linear low-density polyethylene.

The article presents the results on the selection of the composition of new materials for the production of fuel cans. The choice of components was carried out in order to ensure the import substitution of raw materials currently used on the technological line of Sakhaneftegazsbyt JSC. The developed materials are characterized by the required level of physical, mechanical and electrical conductive properties, and are also resistant to the influence of transported media and climatic factors of the Republic of Sakha (Yakutia).
