DOP prices fluctuated and fell in September 

According to the SunSirs commodity market analysis system, as of September 30th, the price of DOP was 7,367.50 RMB/ton, a 2.92% decrease from the price of 7,589.17 RMB/ton ONSeptember 1st. DOP prices fluctuated downward in September. DOP companies' operating loads consolidated, with a slight decrease in operating rates and a slight reduction in DOP supply. Raw material isooctanol fluctuated downward, while phthalic anhydride prices stabilized, reducing DOP costs and increasing downward pressure on DOP prices. Due to insufficient quality during the September shopping season, downstream demand was unlikely to improve, resulting in tepid inquiries for DOP purchases and weak DOP transaction volume. Declining costs and weak supply and demand led to a fluctuating decline in plasticizer prices in September.

The price of raw material isooctanol fluctuated and fell in September

According to the SunSirs commodity market analysis system, as of September 30th, the price of isooctanol was 6,666.67 RMB/ton, a 7.62% decrease from the price of 7,216.67 RMB/ton on September 1st. In September, isooctanol plant installations remained stable at a high level, with the utilization rate remaining stable at 96%. New isooctanol production capacity was added, increasing supply. In September, the price of isooctanol fluctuated downward, driven by falling plasticizer costs and increasing downward pressure on DOP prices.

In September, the price of raw material phthalic anhydride stabilized weakly

According to the SunSirs commodity market analysis system, as of September 30th, the price of OX based phthalic anhydride was 6,293.33 RMB/ton, a slight decrease of 0.11% from the price of 6,300 RMB/ton on September 1st. In September, OX prices rose, while industrial naphthalene prices fluctuated and stabilized, maintaining support for phthalic anhydride costs. Phthalic anhydride equipment loads slowly increased in September, and the operating rates of phthalic anhydride manufacturers rose slightly. This increased phthalic anhydride supply and reduced plasticizer costs put increasing downward pressure on DOP plasticizer prices in September.

Market outlook

Analysts of SunSirs believe that, on the cost side, isooctanol prices fluctuated downward, while phthalic anhydride prices had consolidated weakly, easing downward pressure on plasticizer DOP costs. On the supply side, plasticizer plant operating rates slightly declined, resulting in reduced plasticizer output and supply. On the demand side, the lackluster September sales, the overall economic downturn, and factors such as anti-involutionary competition and the elimination of outdated production capacity had weakened downstream demand. In the future market, due to the weak supply and demand and the weakening cost support, the price of plasticizer DOP is expected to fluctuate and fall.
