Yanshan Petrochemical's 120,000-ton/year high-cis polybutadiene rubber (BR) unit is operating normally, with a planned production volume of 5,400 tons for February 2026. PriceSeek analyzes polybutadiene rubber, giving a bullish-bearish score of -1. The article reports that Yanshan Petrochemical's BR unit is operating normally, with a planned production volume of 5,400 tons for February 2026, indicating a stable increase in supply, which may exert downward pressure on spot prices as ample market supply could suppress prices. Combined with butadiene rubber futures data (e.g., the Shanghai Futures Exchange contract 2603 settlement price of 13,570 yuan/ton, with a change of +350), although recent prices have risen, the new production plan suggests future supply increases, which may weaken the upward momentum of futures prices, constituting a bearish influence.
