Özet
Natural rubber constitutes a critical and largely irreplaceable raw material for the tire industry due to its sustainability, its broad applicability across diverse compound formulations in various tire components, and its relatively lower cost compared to alternatives. In recent years, the demand for natural rubber has steadily increased, primarily driven by rising production and consumption in the tire sector as well as in related industries. However, the environmental challenges associated with this growing demand have intensified concerns. Consequently, research efforts aimed at sourcing natural rubber from alternative and locally available resources have gained significant momentum and prominence. The rubber-based material used in this study was obtained from Gundelia tournefortii, which is an endemic herb raised mainly in the eastern part of T & uuml;rkiye. Initially, the latex from Gundelia tournefortii was collected from the cut body, the impurities were removed, and it was dried till solid form remained. The remaining solid form, as a rubber-based material, was then analyzed by various instrumental techniques and compared with commercial natural rubber obtained from the latex of the Hevea Brasiliensis tree. In the second part of the study, the rubber-based material was used in a standard compound recipe (ASTM D3184) by partially replacing natural rubber in varying proportions. Trial compounds containing the rubber-based material were evaluated in terms of their curing, mechanical and dynamic mechanical properties and compared with the control compound prepared by natural rubber only. Although amorphous, likely resinous, secondary structures reduce the reinforcement imparted by the rubber-based material, DMA analysis showed that rubber-based material at 10-20 phr levels in the standard compound recipe provided improvements in grip and structural response, while maintaining or reducing tan delta at 60 degrees C did not worsen rolling resistance.
