Today, domestic polycarboxylate superplasticizer monomer prices remained stable. In the raw material sector, ethylene oxide trading was driven primarily by rigid demand. The northern market faced slight pressure due to reduced demand, but prices held steady. Ethylene producers in East China faced no immediate pressure to sell excess inventory, leading to a rise in mainstream offers. However, derivative products were largely fulfilling previous orders or contracts, resulting in limited new transactions today and a slight price increase. Fundamentals for the ethylene oxide market provided support. Monomer manufacturers shipped steadily, with some expressing willingness to push prices higher, though downstream acceptance of high-priced goods remained moderate. Overall, it is projected that the main East China EPEG price will remain at 10,000–10,200 CNY/ton on the next business day.
Today, the capacity utilization rate of the domestic polycarboxylate superplasticizer monomer industry stood at 30.01%, representing a week-on-week decline. The gross margin for HPEG monomers was -484 CNY/ton.
On the next business day, domestic polycarboxylate superplasticizer monomer prices are expected to remain temporarily stable. Key raw material ethylene oxide is likely to stay firm at high levels. Units undergoing maintenance have not yet resumed operations, keeping spot supply controllable. Downstream industries across various sectors face weak internal demand, maintaining only rigid consumption. The ethylene market suffers from insufficient available inventory for sale, with derivative expectations remaining bullish, suggesting a high probability of stable-to-stronger prices supported by costs. The monomer market is focused on maintaining prices and shipping goods, with no current willingness to offer discounts. Downstream purchasing sentiment remains cautious, characterized mainly by small-lot procurement based on rigid demand, with transaction volumes negotiated case-by-case. Overall, the main East China EPEG price is projected to range between 10,000 and 10,200 CNY/ton.
① Ethylene Oxide (Raw Material): Ethylene oxide prices are expected to maintain stability. MEG prices are trending weakly, reducing the incentive for co-production units to prioritize MEG output. However, there is no significant new supply entering the market, ensuring short-term tightness persists. On the demand side, key downstream industries are restocking based on rigid needs, while external buyers continue to face pressure, hindering cost transmission downward. Regarding costs, domestic ethylene prices are trending stronger due to limited available supply and bullish downstream expectations, providing positive support for ethylene. In summary, supply-side and cost-side supports remain intact in the short term, leading to an expectation of stable ethylene oxide prices. Continued attention should be paid to upstream and downstream developments.
