Unsaturated polyester resin prices in China declined during the first half of May 2026 due to falling feedstock costs, weak downstream demand, and bearish market sentiment. Lower ethylene glycol, maleic anhydride, and n-butane prices reduced production costs, while easing US-Iran tensions weakened crude oil premiums. Demand from construction, fiberglass, and manufacturing sectors remained sluggish, limiting procurement activity for unsaturated polyester resin. Downstream operating rates also declined, with buyers purchasing only for immediate needs. Despite some maintenance shutdowns, overall supply remained sufficient, increasing market competition and discounting pressure. Looking ahead, weak demand and stable supply are expected to keep unsaturated polyester resin prices under pressure.
