化工日报：青岛港口库存环比继续回升-20251111

1. Report Industry Investment Ratings - RU and NR: Neutral [12] - BR: Cautiously bearish [12] 2. Core Views of the Report - For natural rubber, the supply of raw materials is expected to increase significantly as rainfall decreases in major production areas, which may lead to a decline in raw material prices. Although the cost support is strong, the supply - demand drive is weak. The supply pressure of RU may be less than that of NR in the later stage, which is beneficial for the spread between RU and NR to continue to widen. [12] - For butadiene rubber, the supply is expected to increase this week, while the downstream demand is lackluster and the downstream production is restricted in some areas. The supply - demand situation has weakened, and the price is expected to follow the weak trend of butadiene. [12] 3.
