Plasticizer DOP prices rebounded 

According to the SunSirs commodity market analysis system, as of September 15th, the price of DOP was 7,509.16 RMB/ton, a 0.56% increase from the price of 7,467.50 RMB/ton on September 10th. Prices of raw materials such as isooctanol and phthalic anhydride fluctuated downward, halting the decline in DOP costs and easing downward pressure on DOP prices. Last week, DOP plant operations increased, boosting DOP supply. However, downstream demand was unlikely to improve, with inquiries for DOP purchases remaining flat and limited improvement in DOP transaction volume. The costs stopped falling and plasticizer prices had rebounded.

The price of raw material isooctanol fluctuated and fell

According to the SunSirs commodity market analysis system, as of September 15th, the price of isooctanol was 7,016.67 RMB/ton, a 0.71% decrease from the price of 7,066.67 RMB/ton on September 8th. Last week, isooctanol plant installations remained stable at a high level, with the utilization rate of isooctanol equipment increasing slightly to 96%. This, coupled with significant new production capacity, had increased isooctanol supply. Last week, the price of isooctanol fell slightly, as plasticizer costs stabilized, maintaining support for DOP prices.

The price of raw material phthalic anhydride rebounded and stabilized

According to the SunSirs commodity market analysis system, as of September 15th, the price of OX based phthalic anhydride was 6,300 RMB/ton, a 2.72% increase from the price of 6,133.33 RMB/ton on September 8th. Last week, OX was quoted at 6,400 RMB/ton, a 1.59% increase. Industrial naphthalene prices fluctuated upward, providing increased support for phthalic anhydride costs. Last week, phthalic anhydride equipment utilization increased, with phthalic anhydride plant operating rates at 63%. Phthalic anhydride supply was sufficient, and downstream plasticizer manufacturers were increasing equipment utilization, maintaining demand support for phthalic anhydride. The rebound in phthalic anhydride prices had helped plasticizer costs stabilize, maintaining support for the upward trend in plasticizer DOP prices.

Market outlook

Analysts at SunSirs believe that, in terms of cost, the price of isooctanol fluctuated slightly downward, while the price of phthalic anhydride had rebounded, providing increased support for rising costs for plasticizer DOP. On the supply side, plasticizer plant operating rates increased, plasticizer output had stabilized, 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, with strong supply and weak demand and increased support from rising costs, it is expected that the price of plasticizer DOP will stop falling and rebound.
