Report Title - Synthetic Rubber Weekly Report [1] Report Date - February 8, 2026 [1] Report Industry Investment Rating - Not provided Core Viewpoints - Short - term, the shock center of synthetic rubber moves down, while there is support in the medium - term [2][4] - The short - term of butadiene has limited drivers and will fall from a high level, with support in the medium - term [8][9] Summary by Directory Synthetic Rubber Supply - This cycle, the output of high - cis butadiene rubber is 31,700 tons, an increase of 1,000 tons compared with the previous cycle, a month - on - month increase of 3.25%, and the capacity utilization rate is 78.86%, a month - on - month increase of 2.48 percentage points. Next cycle, it is expected that the butadiene rubber plants of Yangzi Petrochemical and Shandong Yihua will resume normal production, and the capacity utilization rate will increase [4] - As of February 4, 2026, the inventory of domestic butadiene rubber sample enterprises is 33,100 tons, a decrease of 1,300 tons compared with the previous cycle, a month - on - month decrease of 3.78% [7] Demand - In terms of rigid demand, the capacity utilization rate of sample enterprises decreased to varying degrees this week. Next cycle, the capacity utilization rate of tire sample enterprises will further decline. The overall decline of the capacity utilization rate of all - steel tire sample enterprises will be greater than that of semi - steel tire enterprises [7] - In terms of alternative demand, the spread between the main contracts of NR - BR has turned from positive to negative, and it is expected that the alternative demand for synthetic rubber will gradually weaken [7] Valuation - The static valuation range of the butadiene rubber futures fundamentals is 12,300 - 13,200 yuan/ton. The speculative nature has weakened, and the upward valuation pressure has gradually increased. The effective support level is the cost line of butadiene rubber, and butadiene is expected to support the butadiene price from the cost side [4] Strategy - Unilateral: After over - buying, short on rallies according to the valuation; the upper pressure is 13,200 - 13,300 yuan/ton, and the lower support is 12,500 - 12,600 yuan/ton (supported by the NR - BR spread and butadiene cost) - Cross - variety: The NR - BR spread gradually enters a low - level shock, and it is recommended to pay attention to the position of widening the spread later [6] Butadiene Supply - This cycle (January 30 - February 5, 2026), the estimated weekly output of Chinese butadiene industry sample enterprises is 116,500 tons, an increase of 3,000 tons compared with the previous cycle, a month - on - month increase of 2.61%. Next week, it is expected that the weekly output of Chinese butadiene sample enterprises will be about 119,500 tons, continuing to increase compared with this cycle [10] Demand - In the medium - term, the operating rates of butadiene rubber and styrene - butadiene rubber remain high, and the demand for butadiene remains at a year - on - year high. In the short - term, with the decrease of butadiene rubber plant overhauls, it is expected that the rigid demand for butadiene in synthetic rubber will remain high [10] - In the ABS sector, the inventory pressure is relatively large, and it is expected that the demand for butadiene will only maintain a constant amount, with relatively limited increments [10] - In the SBS sector, the operating rate has increased slightly, and the rigid demand for butadiene remains unchanged [10] Inventory - This cycle (January 29 - February 4, 2026), the domestic butadiene inventory decreased, with the total sample inventory decreasing by 4.20% compared with last week. Among them, the sample enterprise inventory decreased slightly by 2.86% month - on - month, and the sample port inventory decreased by 5.19% month - on - month [10]
