In this work, the properties of a composite material derived from fluoroplast and bentonite are examined. The results of the investigation of tribal properties obtained on the basis of fluoroplast and bentonite filler with concentrations of 0.1% are presented; 0.2%; 0.5%; 1%; 2%; 5%. Wear resistance at 5 wt. % bentonite in PTFE increases 117 times compared to the original PTFE after 1 hour and 65 times after a three-hour test.

This paper presents the results of studying of the physics and mechanical and partially tribotechnical properties of fluoroplast-based and bentonite filler. Research has shown that elasticity increases at bentonite concentrations of 0.2% and 0.5%, then decreases sharply. The wear resistance (1h. test) at 5 wt.% of bentonite in PTFE increases 116 times relative to the initial PTFE.
