The paper presents a comparative estimation of technological capabilities of domestic polymer quenchants with different chemical composition such as UZSP-1, Kamgidrol-ZAK and Acresol. The influence of polymer concentration on cooling ability is presented. Intervals of working temperatures for each quenchant were defined and the influence of industrial pollution on the cooling ability was estimated. The paper makes evaluation of the operational stability and the effect of anti-corrosion additives on the cooling ability of each to the quenching medium. There are practical recommendations on application of quenchants in the industry.
