On January 16, Zhejiang Petrochemical's 480,000-ton/year bisphenol A (BPA) plant operated at 90% capacity in its first phase. The second-phase unit was shut down for maintenance on December 10 and is expected to restart on January 20. The products are mainly supplied to the downstream 520,000-ton/year polycarbonate (PC) plant. Currently, the second-phase PC plant is gradually entering its maintenance period.

PriceSeek Analysis on Bisphenol A:
Bull-Bear Score: 1
The shutdown of Zhejiang Petrochemical's second-phase BPA plant for maintenance has led to reduced supply. The first-phase plant operating at 90% capacity only partially compensates for the loss, resulting in overall tight supply. Although downstream PC plant maintenance reduces demand, the supply shock dominates, providing short-term support for spot prices. A slight price increase is expected.

Epoxy Resin:
Bull-Bear Score: 1
As the main raw material for epoxy resin, the tight supply of BPA is driving up its cost, which may be passed on to epoxy resin production, increasing upward pressure on spot prices. No changes in demand were mentioned, with cost-push factors dominating the positive impact.
