On January 30, the bidding and sales situation of some domestic butadiene enterprises: Dongming Petrochemical sold 336 tons externally with a base price of 10,500 yuan/ton; Satellite Chemical raised the price by 200 yuan/ton, implementing 10,600 yuan/ton; Yantai Wanhua auctioned 196 tons with a base price of 10,400 yuan/ton. The restart of domestic butadiene maintenance units led to a slight increase in production. However, tight spot supply and the rise in downstream synthetic rubber futures boosted the market, with merchants showing strong price support. The short-term market is expected to be strong, and subsequent transactions will be closely monitored. PriceSeek analysis of butadiene, long-short score: 1.5. The article indicates that the spot supply of butadiene is tight, and merchants have a strong price support mentality. Enterprises such as Dongming Petrochemical, Satellite Chemical, and Yantai Wanhua either set base prices for auctions or raised prices (e.g., Satellite Chemical increased to 10,600 yuan/ton). Coupled with the rise in downstream synthetic rubber futures boosting demand, the short-term market is expected to be strong. Combined with butadiene rubber futures data (e.g., contract 2701 closing price of 13,585 yuan/ton, up 295 points), the rise in downstream futures further supports butadiene demand, benefiting the upward trend of spot prices. Although the restart of units led to a slight increase in production, overall bullish factors dominate. A score of +1.5 reflects a relatively strong positive impact.
