Sumitomo Rubber has developed Tire Aerodynamics Simulation, a simulation technology for the tire development process. In addition to reducing rolling resistance of tires, it is extremely important to reduce aerodynamic drag around tires in order to improve fuel efficiency (electric power consumption) of EVs. By visualizing the airflow near the tires of a moving vehicle through a proprietary simulation that...
Ube will expand its silicon nitride production facility at its Ube Chemical Factory to meet a sharp increase in demand, especially for bearings and substrates for electric vehicles (EV). The company’s silicon nitride is a high-grade powder produced using a proprietary imide thermal decomposition method. It is characterized by uniform grain size and low impurity content, and its fine structure...
