On August 21, the benchmark price of phthalic anhydride on SunSirs was 6,233.33 RMB/ton, down 6.27% from the beginning of this month (6,650.00 RMB/ton).

On August 21st, the phthalic anhydride market in East China saw a weak and consolidating trend. The mainstream quote for OX-based phthalic anhydride was 6,000-6,200 RMB/ton, while the market price for naphthalene-based phthalic anhydride was 5,900-6,100 RMB/ton. Industrial naphthalene prices fluctuated and stabilized, while OX prices fluctuated and declined, weakening the cost support for phthalic anhydride. Downstream plasticizer prices also saw a weak and consolidating trend. Plasticizer manufacturers maintained stable equipment operating rates, and downstream purchasing remained supportive. Phthalic anhydride was primarily purchased on demand, with stable demand and stable equipment operating rates at phthalic anhydride manufacturers. Phthalic anhydride supply was ample, and inventories were low. It is expected that phthalic anhydride market will consolidate weakly in the future.

On August 21st, the phthalic anhydride market in Shandong Province was weakly consolidating.

The price of raw material OX fluctuated downward, while the price of industrial naphthalene stabilized. This weakened the cost support for phthalic anhydride, and the downstream plasticizer market was weak and consolidating. Phthalic anhydride manufacturers resumed production, and the operating rate of phthalic anhydride enterprises remained stable. Overall, the phthalic anhydride market was adequate, plasticizer enterprises increased their workload, and the demand for phthalic anhydride increased. Phthalic anhydride prices are expected to consolidate weakly in the future.

Domestic spot supplies were ample, while prices for raw material OX fluctuated downward. Prices for industrial naphthalene stabilized, reducing the cost of phthalic anhydride. Downstream plasticizer prices stabilized, with production ramping up. The demand for phthalic anhydride still exists, and downstream purchases are still in demand. The phthalic anhydride market is expected to consolidate weakly in the future.
