III. Market Outlook

Today, domestic polycarboxylate superplasticizer monomer prices are expected to remain stable or trend slightly higher. The primary raw material, ethylene oxide, is likely to maintain stability. Units undergoing maintenance have not yet resumed operations, keeping short-term market supply in a state of tight balance. Downstream demand remains weak as customers steadily consume existing contract volumes. Supply shortages in the ethylene market persist, but most derivative products show limited willingness to chase higher prices, leading to generally stable-to-firm pricing supported by costs. Monomer producers are primarily focused on maintaining prices while selling inventory. Downstream buyers are mostly adopting a wait-and-see approach, with limited acceptance of high-priced goods; transactions are negotiated based on volume. In summary, the price for EPEG in the key East China market is projected to range between 10,400 and 10,600 yuan/ton today.
