In this study, the effect of glass spheres on the physical and mechanical properties of NR-SBR elastomer-based shoe sole material was investigated. In the experiment, the blend of natural rubber (NR-RSS3) and styrene butadiene rubber (SBR 1502) in certain amounts were considered to use. Therefore, 2 newly developed glass sphere blends were prepared and tested. The new blends exhibited much better mechanical properties than the traditional ones. The results showed that glass spheres between 5 -13.5% in the new blends resulted in 23 to 31% decrease in the material cost. Additionally, the new blends exhibited higher mechanical properties compared to that of traditional ones.
Key words: Elastomers and rubber, vulcanization, physical properties.
