China to build 620,000 t/y new butadiene capacity in 2026

In 2026, China is set to add 620,000 t/y new butadiene capacity, and the startup schedule is concentrated in Q4. Demand growth is projected to outpace supply in the first three quarters, before supply accelerates and exceeds demand in Q4. Note that actual commissioning may vary depending on construction progress and profitability, differing from current forecasts.

In 2026, China plans to start up 4 new butadiene units with a total capacity of 620,000 tonnes/year. Downstream capacity expansions in SBS, PBR, SBR, ABS, and SBR latex are expected to raise butadiene consumption by 28,000 t/y.
