Phthalic anhydride prices fluctuated and fell in September 

According to the SunSirs Commodity Market Analysis System, as of September 8th, the price of OX based phthalic anhydride was 6,133.33 RMB/ton, a 2.65% decrease from the price of 6,300 RMB/ton on September 1st. In September, OX prices rebounded, while industrial naphthalene prices stabilized, providing increased support for phthalic anhydride costs. Phthalic anhydride equipment utilization stabilized in September, with phthalic anhydride plant operating at 60% and supply stable. Downstream plasticizer prices fluctuated but stabilized, with plasticizer plant operating rates consolidating at high levels. Phthalic anhydride demand was limited, leading to a fluctuating decline in phthalic anhydride prices in September.

Phthalic anhydride costs rose

On September 8, Sinopec's phthalate price was 6,400 RMB/ton, a 1.59% increase from 6,300 RMB/ton at the beginning of September. Industrial naphthalene prices stabilized, while OX prices rose, leading to an increase in phthalic anhydride costs. Phthalic anhydride equipment maintained stable operating loads in September, with phthalic anhydride plants operating at 60% capacity, ensuring a stable supply of phthalic anhydride.

Demand side: Downstream production was stable and DOP prices fluctuated and fell

According to the SunSirs commodity market analysis system, as of September 8, the price of DOP was 7,517.50 RMB/ton, a 0.94% decrease from the price of 7,589.17 RMB/ton on September 1. Declining costs increased downward pressure on DOP prices. DOP plant operating rates stabilized in September, and demand for phthalic anhydride remained stable, providing little support for rising prices.

Future outlook:

Analysts of phthalic anhydride product data from SunSirs believe that, on the demand side, plasticizer plant operations were stabilizing, and plasticizer output was stable, resulting in weak demand for phthalic anhydride. Regarding costs, OX prices rebounded, while industrial naphthalene prices fluctuated and stabilized, leading to rising phthalic anhydride costs. In the future market, the cost of phthalic anhydride will increase, and the price of phthalic anhydride is expected to rebound in the future market.
