According to the monitoring data of SunSirs, the average price of PS ordinary materials at the beginning of last week was 9,966 RMB/ton, and the average price of PS ordinary materials at the weekend was 9,933 RMB/ton, down 0.33%.

At present, the PS market is in a narrow and volatile market. The upstream styrene price continues to rise, while the downstream demand remains strong. The shipping pace of merchants is slow. The quotation of mainstream brands excluding tax is as follows: Zhenjiang Chimei PG33 is quoted as 11080 RMB/ton, Taiwan Chemical 5250 as 9,670 RMB/ton, Ningbo Taihua 535N as 9,300 RMB/ton, Shanghai SECCO 123P as 9,290 RMB/ton, Thailand Petrochemical 150 as 10,070 RMB/ton, and Guangzhou Petrochemical 525 as 8,770-8,800 RMB/ton.

PS petrochemical manufacturers rose and fell, but the actual transaction was weak. Businesses may operate cautiously, and the market lacks good news support. The mainstream price of GPPS in the East China market is 8,900-11,100 RMB/ton, and the mainstream price of HIPS is 9,900-11,300 RMB/ton.

PS market turnover is light, and short-term China domestic PS market is expected to operate in a narrow range.
