Plasticizer DOP prices fluctuated and fell in September 

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 September 1 price of 7,589.17 RMB/ton. The fluctuating prices of the raw materials, isooctanol and phthalic anhydride, had led to lower DOP costs, increasing downward pressure on DOP prices. DOP plant operating rates stabilized in September, ensuring sufficient DOP supply. Downstream demand was unlikely to improve, with inquiries for DOP purchases remaining flat and limited improvement in DOP transaction volume. Increased supply and lower costs had led to a fluctuating decline in plasticizer prices.

The price of raw material isooctanol fluctuated and fell in September

According to the SunSirs commodity market analysis system, as of September 8th, the price of isooctanol was 7,283.33 RMB/ton, a 3.32% decrease from the 7,533.33 RMB/ton on August 1st. In September, isooctanol plant capacity remained stable at a high level, with a 95% utilization rate. This, coupled with significant new production capacity, increased supply. Downstream plasticizer manufacturers maintained stable operating rates, providing limited support for isooctanol demand. This increased supply coupled with limited demand support led to a volatile decline in isooctanol prices in September. Declining plasticizer costs increased downward pressure on DOP prices.

The price of raw material phthalic anhydride 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% capacity. Phthalic anhydride supply remained stable, while downstream plasticizer plant utilization remained stable, providing limited support for phthalic anhydride demand. Phthalic anhydride prices are expected to rebound in the future, plasticizer costs will stabilize, and downward pressure on plasticizer DOP prices will ease.

Market outlook

Analysts of SunSirs believe that, with the price of isooctanol fluctuating downwards and phthalic anhydride prices rebounding, downward pressure on plasticizer DOP costs remained. On the supply side, plasticizer plant operating rates were consolidating, plasticizer output was stable, and plasticizer supply was sufficient. On the demand side, the overall economic downturn, coupled with anti-involutionary competition and the elimination of outdated production capacity, had weakened downstream demand. In the future market, the supply is strong and the demand is weak, and the pressure of cost reduction still exists. It is expected that the price of plasticizer DOP will fluctuate and fall in the future market.
