Many scientific publications and articles deal with the properties of elastomeric blends (rheological properties, vulcanization characteristics, mechanical properties, etc.) regardless of the so-called thermal history of the blend depending on the mixing process (Sivaselvi et al. 2021; Jong 2019). Each elastomeric blend is created by a mixing process that merges the individual materials into a whole and partially forms the future properties of the blend itself. Mixing conditions (mixing speed, mixing temperature, etc.) of elastomeric blends can be adjusted, which affects its thermal history. In addition to the mentioned conditions, the blend itself is made up of several components (their effect is known and described), which, by their content, composition, and type, also affect the thermal history of the prepared elastomeric blend (Hasan et al. 2018). The presented work deals with the influence of the order of adding individual chemicals to the mixing process, their influence on the measured indicators of the mixing process (mixing torque, real blend temperature), and subsequently on the rheological properties, vulcanization characteristics, and mechanical properties. The influence of the order of adding chemicals to the mixing process can be an alternative to changing the recipe or adjusting the mixing parameters with an economically neutral footprint (since the time, speed, temperature of mixing, and the content of individual chemicals do not change). The obtained results show a significant influence especially in rheological properties and vulcanization characteristics, on the contrary, the tensile properties obtained minimal values change due to the change in the order of the chemicals in the mixing process.
