Domestic polycarboxylate superplasticizer monomer prices continued their downward trend today. The raw material ethylene oxide (EO) market saw transactions primarily driven by essential demand, with prices maintaining firm levels despite being high. Today, ethylene producers faced limited external sales pressure and continued to focus on pre-sales. Downstream derivative manufacturers had completed holiday stockpiling, resulting in weak buying interest and limited inquiries. New order transactions were scarce. Although cost support for EO remains present, the monomer market is characterized by discounted shipments. Pre-holiday restocking activity from downstream users was low, leading to a sluggish trading atmosphere. In summary, the primary East China EPEG price is forecasted to reach 10,600–10,800 CNY/ton on the next working day.
Today, the capacity utilization rate for the polycarboxylate superplasticizer monomer industry stood at 24.21%, reflecting a month-on-month decline. The gross margin for HPEG monomers was 71 CNY/ton.
On the next working day, domestic polycarboxylate superplasticizer monomer prices may experience slight weakness or minor adjustments. Key raw material ethylene oxide (EO) prices are expected to remain relatively stable. Supply availability may fluctuate within a narrow range. Downstream consumption will likely be driven by essential demand, while sentiment in the ethylene market remains poor. It cannot be ruled out that producers may offer slight discounts post-holiday, potentially causing ethylene prices to loosen slightly. Cost-side support may be moderate. The monomer market will continue to rely on discounted shipments, with downstream users adopting a cautious approach to restocking based on immediate needs. New orders will be released sporadically, with transactions negotiated individually. In summary, the primary East China EPEG price is projected to range between 10,400–10,600 CNY/ton.
① Ethylene Oxide (Raw Material): EO prices are currently stable. On the supply side, glycol prices have declined, reducing the profitability incentive for switching production to glycol, which may increase pressure on available EO supplies. On the demand side, mainstream downstream derivative prices are trending downwards amid volatility. Transactions are limited to essential demand, resulting in weak absorption of EO supply and difficulty in releasing incremental demand. Regarding costs, spot ethylene prices have loosened slightly but remain generally strong overall. Downstream factories are purchasing cautiously, and market trading activity has cooled. Overall, cost support provides some floor for prices, suggesting EO prices may maintain stability. Continued monitoring of upstream and downstream developments is recommended.
