① Raw Materials: Ethylene oxide (EO) prices in East China reached 9,700 RMB/ton, while domestic ethylene prices rose to 8,875 RMB/ton.
② Demand: Spot transactions were driven by rigid demand; downstream buyers entered the market cautiously, purchasing selectively at lower price points.

Domestic polycarboxylate superplasticizer monomer prices remained stable today. In the raw material sector, supply and demand for ethylene oxide showed no significant conflict; downstream consumption remained steady, supporting firm prices. Regarding ethylene, after aggressive shipping in previous periods, available inventory among production enterprises in East China is currently limited. Additionally, an MTO unit in Nanjing shut down over the weekend and today, providing bullish support to the supply side and driving prices higher. The fundamental outlook for the ethylene oxide market remains decent. Monomer holders primarily maintained stable pricing while shipping goods, whereas downstream buyers replenished inventory based on rigid spot demand. Consequently, the price of EPEG in the key East China market is projected to remain at 10,000–10,200 RMB/ton on the next working day.
Today, the operating rate of the domestic polycarboxylate superplasticizer monomer industry stood at 30.01%, a week-on-week decline. The gross margin for HPEG was -484 RMB/ton.
On the next working day, domestic polycarboxylate superplasticizer monomer prices are expected to remain largely stable. Key raw material ethylene oxide may also stay stable as the market adopts a wait-and-see approach. Trading will likely continue to be driven by rigid demand, with downstream industries consuming contracted volumes. Pressure to ship ethylene has eased, with some high-priced transactions gaining volume, suggesting a high probability of short-term price stability supported by fundamentals and cost floors. In the monomer market, steady shipping remains the norm; sellers are reluctant to offer low-priced inventory, while downstream buyers engage in small-volume spot replenishment with low willingness for bulk purchases. Transactions are negotiated based on volume. Overall, the price of EPEG in the key East China market is forecast to range between 10,000 and 10,200 RMB/ton.
① Ethylene Oxide (Raw Material): Ethylene oxide prices are expected to trade stably. Monoethylene glycol (MEG) prices have retreated, raising expectations for co-production units to shift product mix. Combined with the fact that trading is dominated by contract orders and spot availability is limited, the supply situation within the market remains tight in the short term. On the demand side, major downstream industries have stocked up ahead of scheduled maintenance, leading to rigid follow-through in market demand. Regarding costs, domestic ethylene prices are stable, though available ethylene inventory in the market has increased. Overall, the supply side provides floor support, so ethylene oxide prices are expected to remain stable. Continued monitoring of upstream and downstream developments is required.
