Abstract

In this article investigates the effect of the content of plasticizers on the properties of rubbers based on rubber BNKS-18 AMN. The traditional, widely used dioctyl phthalate (DOP), as well as the more modern, environmentally friendly dioctyl terephthalate (DOTP), were used as plasticizers. It has been established that the introduction of plasticizers contributes to the production of rubbers with an improved complex of operational properties, such as elasticity, frost resistance, resistance to the corrosive media SZhR-3. At the same time, according to the research results, it was revealed that the introduction of plasticizers in an amount of 20 phr leads to the most noticeable improvement in these properties. In terms of physicomechanical and low temperature properties, the samples containing DOTP significantly exceed those of the samples containing DOP. Thus, our data showed that the use of DOTP is promising as an alternative to the widely used DOP
