On November 20th, the East China phthalic anhydride market saw a weak but stabilizing price trend.

Industrial naphthalene prices consolidated, while OX prices fluctuated but stabilized, leading to stable phthalic anhydride costs. The downstream plasticizer market recovered, with plasticizer manufacturers increasing their operating rates. Downstream demand was primarily for immediate needs, and phthalic anhydride purchases were mainly on an as-needed basis. Demand for phthalic anhydride remained strong, with manufacturers stabilizing their operating rates, resulting in ample supply and low inventory levels. The phthalic anhydride market is expected to stabilize in the near future.
