In early December, the domestic PS market was mainly focused on consolidation and operation. Most spot prices of certain brands have limited fluctuations. According to the bulk ranking data of SunSirs, as of December 9th, the benchmark price of SunSirs's PS was 7,533.33 RMB/ton, with a month on month increase or decrease of +0.44%.

Supply level: Recently, the operating rate of the domestic polystyrene industry has continued to rise steadily, with the overall load narrowly increased to about 61%. The supply of genuine materials is abundant, with only a few models experiencing tight supply. The current inventory position is relatively controllable, and there are still expectations of relaxed market supply. Overall, the supply side's support for PS is average.

Cost factor: The styrene market rose at the beginning of this month. Although the raw material pure benzene market is constrained by demand and hindered from rising. However, recently there have been many unplanned shutdowns of styrene plants, and the supply side is gradually strengthening. At the same time, downstream profits have recovered and production has rebounded, with demand steadily following suit. The supply and demand of styrene in the future may continue to maintain a tight balance pattern, with prices likely to fluctuate within a range, providing sufficient support for the cost side of PS.

On the demand side: Affected by the weakened profitability of terminal enterprises, the downstream electrical casing industry of PS has seen a significant decline in production compared to the same period last year, and there is no expected increase in terminal load in the future. The downstream demand for PS is increasing rapidly, and the overall stocking logic of the enterprise is maintaining a high demand for replenishment, resulting in a slowdown in the flow rate of goods supply. Merchants' inventory positions are deadlocked, the market maintains a cautious atmosphere, and trading momentum is average. Overall, the demand side provides average support for the PS market.

At the beginning of December, the domestic PS market fluctuated strongly. After the production load of the aggregation plant increased, it remained strong, and consumer demand was mainly balanced. Business analysts believe that upstream styrene has currently risen to a high range, and the subsequent increase may be limited. At the same time, there is a lack of positive guidance on the demand side of PS in the short term, and it is expected that it may enter a consolidation market.
