The price of isooctanol fluctuated and fell in September
According to the SunSirs commodity market analysis system, as of September 8, the price of isooctanol was 7,283.33 RMB/ton, a 3.32% decrease from the price of 7,533.33 RMB/ton on August 1. In September, isooctanol production 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 production, but demand for isooctanol from plasticizers was limited. With increased supply and limited demand, the price of isooctanol fluctuated downward in September.
Downstream plasticizer 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 insufficient demand for isooctanol had limited support for price increases.
Market outlook
Analysts of SunSirs believe that on the supply side, isooctanol manufacturers were operating at a high and stable capacity, coupled with significant new production capacity, resulting in an oversupply of the alcohol. On the demand side, DOP prices were fluctuating downward, and demand for isooctanol was insufficient. Looking ahead, with increased supply and limited demand for isooctanol, prices are expected to fluctuate downward.
