Abstract:
Thermoplastic elastomers (TPE) are a unique class of polymer composite materials that have garnered considerable interest in the polymer industry due to the combination of thermoplastic and elastomer properties. The elastomeric component provides high flexibility of macromolecules and the possibility of significant deformations, while the thermoplastic phase is responsible for mechanical strength and rigidity at low temperatures as well as plasticity upon heating. A fundamental difference between TPEs and traditional elastomers is the absence of chemical cross-linking, which enables to process by all common methods applied in plastics technology. Changing the chemical structure of TPE components makes it possible to achieve wide variability in the properties of materials based on them. Dynamic vulcanization is the process of simultaneous formation of a three-dimensional spatial network of elastomer and mixing with plastic. This method has discovered the path to the obtaining of thermoplastic vulcanizates (TPV) or thermoplastic rubbers (TPR) with a unique combination of properties. As a part of this work, a TPR formulation highly resistant to aggressive media based on NBR-40 and ABS-plastic was developed. It was assumed that two types of resins introduced simultaneously would demonstrate a synergistic effect, which would affect the increase in the elastic and strength characteristics of the obtaining material. The carried out physical and thermal stability tests showed that the tensile strength of a TPR with an elastomer-plastic mass ratio of 75:25 reaches 15 MPa at elevated temperatures. The developed material also passed tests for resistance to swelling in solvent environments: the degree of swelling in oils did not exceed 2%, and in gasoline it was within 10%.
