Abstract. Polymer composites based on high-density polyethylene, carbon black and low-molecular-weight polyethylene were obtained. The addition of low molecular weight polyethylene increases the melt flow index and helps to reduce the particle size of the dispersed phase in the composition. XRD analysis showed changes in the structure of both carbon black and high-density polyethylene in the presence of low molecular weight polyethylene in the composition. At the same time, the tensile strength at yield, elongation at break and thermal stability of the composition meet the requirements for raw materials for the production of pipes based on polyethylene.

Key words. Low-molecular-weight polyethylene, lubricant, high-density polyethylene, carbon black, melt flow index, structure.
