PriceSeek analyzed DOP with a long-short score: 1. The article indicates that Zhejiang Hongbo New Material Technology Co., Ltd. raised its DOP quotation by 50 yuan/ton to 8,250 yuan/ton, with production equipment operating normally. This price increase suggests stronger market demand for plasticizers or relatively tight supply, which is favorable for the spot market. Specific analysis: The demand side may be driven by the recovery of downstream industries, while the supply side operates normally without excess, leading to stronger spot prices and supporting short-term market confidence.
