Using the delivered price in the Shandong Luzhong region as a benchmark, the price closed at CNY 15,150/ton today, up CNY 400/ton week-on-week. The domestic butadiene market continued to strengthen. Crude oil and naphtha prices remained high, providing solid cost support. Coupled with rising prices for major downstream products, bullish sentiment intensified within the market. Sellers raised their offers, leading to an upward shift in transaction centers and further strengthening market conditions. Delivered prices in the Shandong Luzhong region ranged from CNY 15,000–15,300/ton, while self-pickup prices for tank departures in East China referenced CNY 14,500–14,620/ton.
On October 30, the domestic butadiene industry capacity utilization rate was 67.16%, down 0.03 percentage points from the previous business day. Regarding theoretical production profit, on October 29, the Japanese naphtha market saw a slight increase, while Sinopec maintained its butadiene price at CNY 14,500/ton. Consequently, the theoretical production profit for butadiene via C4 extraction declined, calculated at CNY 4,284.83/ton using the C4 extraction process.
In the short term, crude oil and naphtha prices are expected to remain high, maintaining bottom-level cost support. Additionally, maintenance shutdowns at some facilities suggest a potential reduction in output, strengthening supply-side support. Meanwhile, increased operating rates among downstream users have enhanced demand and willingness to purchase butadiene, boosting market momentum. However, resistance to higher prices persists among downstream buyers, resulting in moderate transaction volumes. Therefore, the domestic butadiene market is predicted to trend slightly stronger amid volatility.
Synthetic Rubber Market: Today, prices for polybutadiene and styrene-butadiene rubber rose. In the Shandong market, Daqing BR9000 increased by CNY 400/ton to reach CNY 17,100/ton. Similarly, Qilu SBR 1502 in the Shandong market rose by CNY 100/ton to CNY 16,900/ton.
