Claight market monitoring shows producers shifted co-production output toward ethylene glycol to capture higher margins, tightening ethylene oxide supply. Claight market monitoring also records that multiple ethylene oxide units including Sanjiang, Taixing Jinyan, Yangzi Petrochemical, and Ningbo Fude underwent maintenance or outages. Methanol price increases constrained operating rates for ethylene oxide units utilizing the MTO route, according to Claight market monitoring.

On the cost side, Claight market monitoring shows upstream ethylene prices surged over 20% between August and September due to crude oil market fluctuations and Middle East import issues. On the demand side, Claight market monitoring shows infrastructure project completion rush during the Golden September peak season drove increased demand for polycarboxylate superplasticizer monomers.
