Chempricehub, Oct. 22 —

On October 22, the phthalic anhydride (PA) market in Shandong remained stable. The mainstream negotiated price for PA produced via the ortho-xylene route stood at RMB 10,000–10,100 per ton, while that for PA produced via the naphthalene route was quoted at RMB 9,500–9,600 per ton. Crude oil prices fluctuated upward, maintaining cost support. Raw material ortho-xylene prices stabilized amid fluctuations, and industrial naphthalene prices consolidated, leading to stable production costs for PA. The downstream plasticizer market trended steadily. Operating rates of PA manufacturers increased, ensuring stable market supply. Meanwhile, operating rates of plasticizer enterprises rebounded, weakening demand-driven support for PA. Overall, the PA market maintained a steady trajectory.
