Investigation of Rheological and Mechanical Properties of Rubbers Produced by Sulfur Vulcanization from EPDM Rubbers with Different Ethylene Ratios

Öz

In this study, the effect of ethylene on the rheological and mechanical properties of rubbers was investigated. For this purpose, rubbers were produced by mixing EPDM rubbers containing ethylene in different ratios and curing with sulfur. The formulations were modified so that all samples had the same hardness. Rheometer analysis results revealed that the flow consistency of the Suprene 512 F sample was higher than the other two samples. The curing time of 90% of the sample was later than the other two samples. As a result of the tensile-elongation analysis, it was observed that the Ts/MPa and Eb/% ratios of Suprene 512 F rubber with the highest ethylene content were substantially higher. The hardness analysis revealed that the increase in the amount of ethylene in the rubber was directly proportional to the increase in the tensile breaking strength. In addition, it was observed that the ethylene ratio in rubber linearly affected the hardness change after vulcanization. While making rubber blend formulations, it should be considered that the ethylene ratio in the mixture will directly affect the change in the hardness of the product formed as a result of vulcanization.
