2026 Q2 Outlook

ABS/GPS/EPS

Supply of raw materials has been hit hard by Middle East geopolitical conflicts and the equipment failure of CPC’s New No. 3 Naphtha Cracker. In Q2, the ABS/GPS/EPS markets are characterized by High costs, Supply disruptions and Spread realignment.

• High costs and supple shortages have widened spreads, but reduced output are squeezing overall profits.
• Chinese over-supply and low-price competition have caused narrowing spreads.
• Market trends for ABS/GPS/EPS will be driven by the raw material supply dynamics.
