January 16th, News

January Plasticizer DOP Prices Fluctuate and Rise in China

According to the commodity market analysis system, as of January 16, the DOP price was 7492.50 CNY/ton, an increase of 2.27% from the DOP price of 7325.84 CNY/ton on January 1. The operating load of DOP plasticizer enterprises in China is stable, with an operating rate of around 63%, and DOP production is stable. The prices of 2-ethylhexanol and phthalic anhydride have increased, leading to a rise in raw material costs. The increase in DOP costs, combined with sufficient supply, has led to a fluctuating increase in the price of plasticizers.

Plasticizer DOP manufacturers in China have seen a slight decrease in production.

In January, the operating load of DOP manufacturers in China decreased slightly, with the operating rate dropping to 63%. The production and supply of DOP decreased, but there is still upward momentum for DOP prices.

Raw material iso-octanol prices are fluctuating and rising.

According to the commodity market analysis system, as of January 16, the price of 2-ethylhexanol was 7033.33 CNY/ton, an increase of 1.69% from 6916.67 CNY/ton on January 1. The maintenance of 2-ethylhexanol production facilities in China has been completed, and the operating load of 2-ethylhexanol plants has increased, with a 95% operating rate, ensuring sufficient supply of 2-ethylhexanol. The significant rise in propylene prices has increased the cost support for 2-ethylhexanol. With the fluctuating increase in the price of 2-ethylhexanol, the cost of plasticizers has risen, thereby increasing the upward momentum for DOP.

January Phthalic Anhydride Prices in China Fluctuate and Rise

According to the commodity market analysis system, as of January 16, the price of o-xylene phthalic anhydride in China was 6,266.67 CNY/ton, a significant increase from the price of 5,966.67 CNY/ton on January 1. The price increase was 5.03%. Since late December, the price of phthalic anhydride has stopped falling and rebounded, and the upward trend continued in January. In January, the price of phthalic anhydride increased significantly, leading to an increase in DOP costs and greater support for the rise in plasticizers.

Future Market Expectations

Plasticizer product data analysts believe that in terms of costs, the price of 2-ethylhexanol has fluctuated and risen, and the price of phthalic anhydride has significantly increased, leading to a greater support for the cost increase of DOP plasticizers. In terms of supply, the operating rates of plasticizer enterprises in China have remained weakly stable, with stable plasticizer output, ensuring an adequate supply of plasticizers. Looking ahead, with the increase in costs and sufficient supply but limited demand, it is expected that the price of DOP plasticizers in the Chinese market will experience a strong consolidation.
