Latest Patents
One of his latest patents focuses on radial tires that incorporate short fibers. This design features a cap tread with a tan delta peak temperature of not less than -30 degrees Celsius. The base tread consists of at least 30 parts of carbon black with an iodine adsorption number of 30 to 90 mg/g and a minimum of 10 parts of short fiber oriented in the axial direction. The side wall includes no more than 30 parts of carbon black and at least 10 parts by weight of short fiber oriented in the peripheral direction. Additionally, the bead apex comprises at least 65 parts by weight of carbon black with an iodine adsorption number of 60 to 100 mg/g and at least 20 parts by weight of short fiber oriented in the axial direction or a direction crossing the axial direction. This innovative radial tire is lightweight, has low energy loss, and provides excellent steering stability.
Another notable patent is for a rubber composition for tire treads. This composition consists of a rubber component that includes 20 to 100% by weight of a solution-polymerized styrene-butadiene copolymer rubber. This rubber has a Mooney viscosity ML1+4 of 30 to 200 at 100 degrees Celsius, prepared through copolymerization of styrene, butadiene, and a polyvinyl aromatic compound, followed by coupling with a trifunctional or tetrafunctional coupling agent. The composition also allows for good dispersibility of carbon black, resulting in tires with low rolling resistance and high grip characteristics.
