Advanced technology in ENEOS-SBR: driving tire performance and ecological impact

To reduce CO2 emissions, the automotive and tire industries seek to improve rolling resistance, wear resistance, durability and grip in compounds, raw materials and synthetic rubber, along with using sustainable and recycled materials. Research on styrene-butadiene rubber (SBR), the main tread compound material, has focused on modification technology, increasing molecular weight to improve tensile strength and wear resistance. In this study, we utilize Eneos's accumulated expertise in polymer technology to introduce various chemical modifications to the backbone of SBR, investigating how these changes impact the physical properties and composition of the compound, and explaining their contribution to reducing CO2 emissions.
