The effect of polyketone thermal processing duration on the rheological properties of the melts and the physical and mechanical characteristics of the samples, obtained by injection and compression molding methods, is studied.

This article is devoted to the investigation of physicomechanical, tribological, and thermophysical properties of the polyamide antifriction composition, containing shungite and graphite with a total concentration of 2.5%. It is intended for the manufacture of elements of power hydraulic cylinders tribo-conjugation for agricultural machinery. A comparison of the characteristics of the developed composition with the characteristics of caprolon and the commercial carbon-filled composite UPA6-15A.
