Background. Recently, in many countries of the world, in the manufacture of shoe soles, increasing attention has been paid to the application of the injection molding method using efficient raw materials, such as thermoplastic rubbers (TPR) based on different types of rubbers, polyvinyl chloride (PVC) plastics, ethylene copolymer with vinyl acetate (EVA) and thermoplastic elastomers of composites. If we take into account that most of the raw materials and components used for shoes, including the finished sole, are brought to our republic from foreign countries, mainly from China, the problem of producing polymer materials using local ingredients and ingredients will be even more obvious. In this regard, we investigated injection-molded elastopolymer mixtures in the aggregate of components, especially synthetic butadiene-nitrile rubber of the SKN brand and polyolefin resins - low-density polyethylene (LDPE), a product produced by the Shurtan Gas Chemical Complex and PVC plastic compounds, followed by the creation of thermoplastic elastomers TEP) compositions for the production of shoe sole materials. Purpose. to develop the possibility of using local raw materials and components to create polymer compositions with the subsequent production of shoe-based plantar materials on their basis. Methodology. viscosimetry, injection molding. Originality. Taking into account the viscosity and technological properties of different types of rubbers, TEP of a composition of rubbers with LDPE and PVC plastic was obtained and investigated. The dependence of processing temperature and pressure on the type and composition of the elastopolymer composition was determined. Findings. The best fluidity is possessed by isoprene and butadiene-nitrile rubber. Introduction of up to 30 wt. h. LDPE in the composition increases the fluidity at the processing temperature up to four times. To prevent premature scorching, the pressure and temperature of the processing should be regulated, as well as the diameter of the nozzle of the casting unit. Highlights: - molded polymeric materials based on TEP compositions for manufacturing shoe soles were obtained; - the best fluidity is possessed by isoprene and butadiene-nitrile rubber.
