Today, the market price for domestic polycarboxylate superplasticizer monomers remained stable. On the raw material side, spot supply of ethylene oxide (EO) remains tight, keeping prices firmly high. Ethylene producers faced no shipment pressure today, and the market lacked new directional news, leading to stable offers. The fundamental support for the EO market keeps prices firm at high levels, providing a cost floor. Due to insufficient spot supply of monomers, holders have little willingness to offer discounts, while downstream buyers remain cautious about replenishing stock at high prices. In summary, the price of EPEG in the key East China market is expected to range between 12,000-12,200 yuan/ton on the next trading day.
Today, the capacity utilization rate for the polycarboxylate superplasticizer monomer industry was 24.21%, a week-on-week decline. The gross profit margin for HPEG monomers was 1,371 yuan/ton.
On the next trading day, domestic polycarboxylate superplasticizer monomer prices are likely to remain high. Key raw material ethylene oxide (EO) is expected to trade steadily. The supply structure for monoethylene glycol (MEG) will continue, potentially supporting stronger MEG prices. Tight spot availability of EO provides a price floor. Downstream industries maintain essential procurement. Recent ethylene transactions have been sluggish, reducing producers' motivation to push prices higher, so short-term stability is expected, offering cost-side support. Downstream demand for monomers at high prices remains cautious, with a strong wait-and-see sentiment. Spot inventory is limited, and holders are reluctant to discount, leading to quantity-based negotiations. In conclusion, EPEG prices in the main East China market are projected to be around 12,000-12,200 yuan/ton.
① Ethylene Oxide (Raw Material): EO prices are expected to remain high in the short term. On the supply side, spot availability of MEG remains tight, likely supporting stronger prices in the near term. Co-production units are expected to continue producing MEG, limiting the increase in EO spot supply, thus maintaining supply-side support. On the demand side, operating rates across downstream industries may adjust slightly, ensuring steady consumption. Regarding costs, most ethylene derivatives have entered a downward cycle; market buying interest is likely to remain driven by essential needs, leading to firm but consolidated pricing with cost support. Overall, supply and cost factors will continue to support the market in the short term, keeping EO prices firm at high levels. Future developments in upstream and downstream sectors warrant attention.
