The work aims to generalize the existing theoretical studies into the influence of geometrical dimensions of the Maddock element installed on the extruder screw on the mixing quality of polyethylene composition with a silicone rubber in order to establish theoretical laws of the process and to verify them experimentally. A mathematical model of the flow of polymer melts in the working gaps of a single-extruder screw with a Maddock mixing element is formulated. Numerical and simulation experiments were carried out, a technological scheme for producing a composition for an antifriction layer of protective tubes of fiber optic communication cables is proposed, and samples of the new composition were obtained.
