Background. Currently, the rubber industry of the Republic of Uzbekistan is mainly based on imported raw materials, including rubbers and ingredients brought from the outside. All this, ultimately, affect the cost of production. Despite the huge reserves of mineral raw materials available to the Republic, in particular kaolin from various deposits, they still do not find proper use in the production of plastics and rubber. This is primarily due to the lack of a scientifically based approach to solving the tasks. In this regard, a comprehensive study of enriched kaolin "Alliance" as a filler for composite elastomeric materials for various purposes is of considerable scientific and practical interest and allow the solution of problems of import substitution. Purpose. The rationale for the use of enriched kaolin "Alliance", instead of imported expensive kaolin, in the formulation of multi-purpose rubber mixtures. Methodology. We used modern rotary viscometer type MUNI to estimate the viscosity of rubber compounds, as well as a rheometer type M-3000A, designed to study the kinetic parameters of vulcanization. Originality consists in determining the role of the mineralogical composition and peculiarities of the Alliance kaolin structures in the formation of composite elastomer materials with improved processability. Findings. The effect of the kaolin content on viscosity, plasticity, and scorch speed, the optimum vulcanization of rubber compounds based on styrene-butadiene rubber, has been comprehensively described. Highlights: * the possibility of improving the viscosity and plasticity of rubber compounds; * slowing the speed of vulcanization of rubber compounds.
