Abstract

The article is dedicated to studying the potential for enhancing the durability of elastomeric materials based on ethylene–propylene–diene rubber, containing modified aluminosilicate microspheres, against the effects of tropical climates, which include elevated temperatures, humidity, and ultraviolet radiation. The research findings will improve the reliability and extend the service life of rubber products used in tropical regions, which is significant for various industrial sectors—from automotive to construction and energy. Annual field tests of the developed rubbers were conducted in climatic conditions at the Kon Zo and Dam Bay stations in Vietnam. Analysis of the results shows that the addition of unmodified aluminosilicate microspheres to the elastomeric materials has little effect on their resistance to tropical climates. However, the created compositions demonstrated greater durability during testing at the Dam Bay station, where both ultraviolet radiation and high humidity are present. It was shown that the combined treatment of aluminosilicate microspheres with an organoelement modifier and low-temperature plasma contributes to an increased retention of physical and mechanical properties—the samples lose 10–19% less strength and experience virtually no loss in hardness compared to the control sample.
