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

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