China Plasticizers, Chlor-Alkali and Polyols: Weak Demand Limits Cost-Led Rallies

Across Chinese plasticizers, chlor-alkali and polyols, rising feedstock costs created short-term price support, but weak downstream demand remains the larger market force.

Key Takeaways

• Oxo alcohol and plasticizer prices declined for several months as supply exceeded demand.
• Liquid chlorine demand weakened after the seasonal peak, forcing producers to cut prices to manage inventories.
• Flexible- and rigid-foam polyether polyol prices fell with propylene oxide before producers attempted increases in July.

Oxo Alcohols and Plasticizers Rebound with Propylene

Oxo alcohol and plasticizer prices declined for several months as supply exceeded demand. In early July, higher crude and propylene costs lifted 2-ethylhexanol and supported a rebound in DOP and DOTP. By July 16, DOP and DOTP were assessed around RMB 8,350–8,800 per metric ton.

Chlor-Alkali Remains Oversupplied

Liquid chlorine demand weakened after the seasonal peak, forcing producers to cut prices to manage inventories. EDC, VCM and PVC values also declined as feedstock costs and demand softened. Higher crude and ethylene prices generated only a modest PVC rebound in early July.

Polyether and Polyester Polyols Face Buyer Resistance

Flexible- and rigid-foam polyether polyol prices fell with propylene oxide before producers attempted increases in July. Buyers remained cautious in the seasonal slowdown, and transactions were limited to small, immediate-need volumes. Polyester polyols also remained oversupplied as weak synthetic-leather and footwear orders constrained purchasing.

H2 Implications

Cost inflation can create temporary rebounds, but producers will need stronger downstream demand or disciplined operating rates to sustain them.
