The ABS and PS market trend in February basically followed the price fluctuation of styrene, and the overall market rose first and then fell. During the Spring Festival, the ABS and PS plants in China had a negative maintenance adjustment. Although the middle and downstream began to resume production after the Spring Festival, the resumption speed is not as high as expected. The pace of replenishment was also slow, which made some effect on the demand. From the latest tracking, about 1.575 million tons of ABS production capacity was suspended as plant maintenance, decreasing 21.25% compared to the previous month. PS plant maintenance involved about 2.73 million tons of capacity, increasing 50% compared to the previous month.

Table 1: changes of domestic ABS plants in February
From Table 1, during the Spring Festival in 2024, most ABS petrochemical manufacturers kept a relatively low operation level. Huajin Chemical and Lihua Yilijin have been in the state of maintenance at the beginning of the fourth quarter of 2023, and have not yet restarted. CNPC also plans to shut down the 600,000-ton/year ABS plant in Jieyang for maintenance from March 12 to 23. From this point of view, ABS operating rate may be difficult to recover in the short and medium term.

Table 2: changes of domestic PS Plants in February
From Table 2, the production suspended or reduced of PS plant are more concentrated under the industry loss. The operating rate during the Spring Festival holiday has dropped as scheduled and updated the lowest level in recent years. With the end of holiday, the production of PS was still slow to recover, which maintains at a low level overall. At present, Anqing Xingda, Rentai Chemical, Shandong Dowell, Changke New materials, Ineos Styrolution (Foshan), Ningbo Union, Rastar EP Materials, Astor Chemical, Zhejiang Yisu and Zhanjiang New Zhongmei have successively restarted the plants. In addition, Dushanzi Petrochemical plans to suspend production for maintenance during mid-may to mid-July.
The recovery of downstream is slower than expected. During the Spring Festival, the inventory accumulation in the market is obvious, and the upstream cost support is also gradually decreasing. All these factors intensify the contradiction between supply and demand, so that the rigid plastic market rose in February after a correction. In the future market, some domestic maintenance plant will continue to recover, but the recovery of demand remains to be seen. The industry insiders is cautious about the rigid plastic market trend next month, and continue to pay attention to the cost trend, the overall downstream resumption of production and the operating rate of the plants.
