Report Summary 1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - The overall supply of domestic butadiene rubber is sufficient. Although there are some production device overhauls, the production has recovered and increased. Next week, the reduction in supply will gradually be reflected, and the spot offer may decline after the price cut of butadiene rubber and butadiene, which may drive some downstream stocking. The inventory of producers and traders may slightly decrease. In terms of demand, the overall capacity utilization rate will increase as the production scheduling of overhaul enterprises gradually resumes this week, but the increase may be limited due to the production control plan of some enterprises. The short - term forecast range of the br2511 contract is between 11,600 - 12,300 [2] 3.
