In recent years, performance requirements for tires have led to sophisticated and complex due to technological changes in the automotive industry, such as electrification, and the trend toward further reduction of environmental impact to realize a sustainable society. Responding to these new market demands, we have developed a new hydrogenated SBR (HSBR). This HSBR shows significant improvement in tensile strength, ozone durability, and wear resistance compared with conventional SBR.
