SunSirs: Operating Rates Increased, and Isooctanol Prices Rebounded Last Week

November 27 2025 15:15:49     SunSirs (John)

Isooctanol prices rebounded

According to the commodity market analysis system of SunSirs, as of November 24, the price of isooctanol was 6,250 RMB/ton, a decrease of 4.17% compared to 6,000 RMB/ton on November 14. Some companies reduced maintenance of isooctanol equipment, leading to a slight increase in the operating load of isooctanol plants. The operating rate of isooctanol reached 80%, resulting in ample supply. Propylene prices fluctuated upwards, increasing isooctanol costs. Last week, ample isooctanol supply strengthened upward support and weakened downward pressure, leading to a fluctuating upward trend in isooctanol prices.

Raw material propylene rose

According to the commodity market analysis system of SunSirs, as of November 24, the price of propylene was 6,080.75 RMB/ton, a fluctuating increase of 1.93% compared to 5,965.75 RMB/ton on November 14. Last week, the price of propylene fluctuated upwards due to rising raw material prices and increased isooctanol costs, which strengthened the support for the price increase of isooctanol.

Downstream plasticizer DOP prices rebounded and rose

According to the commodity market analysis system of SunSirs, as of November 24, the price of DOP was 6,967.50 RMB/ton, a rebound of 1.22% compared to 6,883.34 RMB/ton on November 14. The increase in DOP costs led to the price rise. Last week, the operating rate of DOP plasticizer manufacturers slightly increased to 70%, resulting in increased DOP production. This strengthened demand for isooctanol, further supporting the price increase of isooctanol.

Market outlook

According to analysts at SunSirs, isooctanol prices were rising due to fluctuating propylene prices and increasing raw material costs, which was driving up isooctanol prices. On the supply side, isooctanol plant operating rates increased slightly, resulting in ample supply. On the demand side, DOP plant operating rates had risen slightly, leading to increased DOP production and stronger demand support for isooctanol. Looking ahead, rising isooctanol costs, coupled with ample supply and recovering demand, will reduce downward pressure and increase upward support for isooctanol prices, leading to a volatile but upward trend in isooctanol prices.
