On February 10th, the bidding and sales situation of some domestic butadiene enterprises: Dongming Petrochemical sold 392 tons externally with a base price of 10,000 yuan/ton; Satellite Chemical raised the price by 200 yuan/ton, implementing 10,200 yuan/ton; Yantai Wanhua's listed price is 10,040 yuan/ton. Recently, domestic butadiene production has slightly increased, but pre-holiday spot supply is tight, with limited supply from producers, and downstream demand remains firm. Coupled with the strong performance of synthetic rubber futures, the market is expected to maintain a slight upward trend, with a focus on post-holiday supply. PriceSeek analysis of butadiene, long-short score: 1.5. The article analysis shows that the spot market for butadiene is tight, with limited supply (Dongming Petrochemical base price 10,000 yuan/ton, Satellite Chemical raised to 10,200 yuan/ton), supported by downstream demand. Combined with limited pre-holiday production increases, prices are expected to maintain a slight upward trend. Butadiene rubber futures (such as the main contract 2611 closing at 12,990 yuan/ton, up 150 yuan) performed strongly, boosting confidence in the butadiene raw material market. Considering the tight supply-demand situation in the spot market and the linkage effect with futures, there is strong positive support for butadiene prices.
