Abstract: The article substantiates the effect of the concentration of polymer thickener on such basic properties of the plastic lubricant as dripping temperature (td.p., °С) and adhesive properties (ADG). It was defined that, unlike (td.p., °С), the ADG indicator is more informative for defining the optimal concentration of the polymer thickener in plastic lubricants produced from secondary raw materials. Determination of the ADG indicator was performed in a laboratory centrifuge, based on the amount of plastic lubricant that remained on the metal plate after the study. This amount should be at the level of 50 % of the initial value. Experimental studies have shown that the optimal concentration in the composition of the lubricant is: in the case of HDPE, 5.0 % for SAE15W-40 oil, 4.3 % for SAE 75W-90 oil, 6.3 % for BP Energol CS68 and HLP-46 oil ; in the case of LDPE, this concentration is equal to 7.0 % for SAE15W 40 oil, 5.2 % for SAE 75W-90 oil, 7.4 % for BP Energol CS68 and HLP-46 oil; in the case of PP, this concentration is equal to 7.5 % for SAE15W-40 oil, 6.2 % for SAE 75W-90 oil, 8.0 % for BP Energol CS68 and HLP-46 oil.
