The 100,000-ton/year high-cis polybutadiene rubber unit of Yangzi Petrochemical was temporarily shut down from February 5, 2026, with the restart time to be determined. PriceSeek's analysis of polybutadiene rubber shows a bullish-bearish score of 1. The temporary shutdown of Yangzi Petrochemical's polybutadiene rubber unit has led to a reduction in supply, which is expected to drive up spot prices. The latest butadiene rubber futures data indicates that the main contract 2605 closed at 12,850 yuan/ton, with a change of -65. However, the supply disruption event may strengthen bullish expectations and boost futures prices, especially as changes in open interest for near-month contracts indicate a positive market response to supply tightness.
