January 23 – On January 23, the 50,000-ton plasticizer production equipment of Zhejiang Hongbo New Material Technology Co., Ltd. operated normally. The DOP (dioctyl phthalate) quotation was 7,950 yuan/ton, an increase of 100 yuan/ton compared to the previous period. Chempricehub analysis of DOP: Bullish/Bearish Score: 1 The article indicates that the spot price of DOP rose by 100 yuan/ton to 7,950 yuan/ton, an increase of approximately 1.27%, suggesting stronger downstream demand or tightening supply, which generally supports the spot price. Normal operation implies stable production, but the price increase may stem from rising costs or active market procurement. Styrene, Bullish/Bearish Score: 1 As a downstream plasticizer of styrene, the rise in DOP quotation reflects increased demand, which may drive higher styrene consumption. Combined with styrene futures data (e.g., the main contract 2603 closed at 7,694 yuan/ton, up 121 yuan), the recent market shows an upward trend. The strengthening demand for DOP may further support futures prices, constituting a positive factor.
