Report Summary 1. Report Industry Investment Rating - No information provided in the report. 2. Core View of the Report - The production of domestic cis - butadiene rubber has increased due to the restart of previously - shut - down devices, and the supply is expected to rise significantly. The inventory level of finished products is likely to increase. In terms of demand, the capacity utilization rate of domestic tires fluctuated slightly last week. Some semi - steel tire enterprises' maintenance plans dragged down the overall capacity utilization rate, while the resumption of work of all - steel tire maintenance sample enterprises drove up the capacity utilization rate. Although there is still room for a slight increase in capacity utilization rate, the general order performance and enterprise production control will limit the increase. The br2510 contract is expected to fluctuate in the range of 11,600 - 12,000 yuan/ton in the short term [2]. 3.
