① Raw Materials: East China ethylene oxide prices remained stable at 9,200 yuan/ton; domestic ethylene prices rose to 9,300 yuan/ton.
② Demand: Downstream buyers were cautious about chasing higher prices for restocking, with purchases limited to rigid demand in small volumes.

Today, domestic prices for polycarboxylate superplasticizer (PCE) monomers continued to rise. Related product ethylene glycol prices also strengthened. The spot supply of ethylene oxide remains tight, keeping its price firm at high levels. In the ethylene market, supply in East China remained tense, and some major producers raised their quotation prices. However, key downstream markets such as styrene showed stagnant trends with weak profitability, resulting in limited acceptance of high-priced goods. Fundamentals in the ethylene oxide market provided support, with prices running high due to cost-side backing. Monomer producers focused on fulfilling existing orders and were reluctant to sell at low prices. Downstream consumers drew down inventories and made rigid-demand restocks, with a strong wait-and-see sentiment prevailing. Consequently, the price of EPEG in the main East China market is expected to reach 11,300-11,500 yuan/ton on the next working day.
Today, the capacity utilization rate in the PCE monomer industry was 24.21%, a month-over-month decline. The gross profit margin for PCE monomer HPEG stood at 1,056 yuan/ton.
On the next working day, domestic PCE monomer prices may trend stronger. Key raw material ethylene oxide prices are likely to remain firm at high levels, while ethylene glycol prices maintain an upward trend. Tight spot supply of ethylene oxide persists. Downstream industries across various sectors are expected to maintain steady consumption. Trading volume in the ethylene market has declined, and producers lack sufficient momentum for further price hikes, suggesting prices will mainly stabilize. Monomer holders may cautiously push prices up, while downstream willingness to chase highs and stockpile remains weak, with transactions primarily driven by rigid demand and negotiated based on volume. In the short term, prices may trend stronger. Consequently, the price of EPEG in the main East China market is expected to reach 11,300-11,500 yuan/ton on the next working day.
① Ethylene Oxide (Raw Material): The ethylene oxide market is expected to consolidate at high levels. On the supply side, with ethylene glycol prices remaining high, co-production units have shifted focus toward producing ethylene glycol, leaving the shortage of ethylene oxide spot supply unresolved. Key downstream industries performed steadily with consistent consumption. On the cost side, available spot ethylene supplies were tight, but expectations of reduced loads or shutdowns for styrene derivatives persisted, leading to fewer rigid-demand buyers and weak momentum for further price increases. High-price transactions faced pressure, though cost support remained intact. Overall, supply and cost factors continue to provide short-term support, keeping prices high. Attention should be paid to upstream and downstream developments going forward.
