Propylene: On the 28th, the price of propylene in Shandong continued to decline, and the mainstream transaction price was 7350-7400 CNY/ton. The market has reduced the profit margin and the supplier shipments have improved compared with the previous period. The market price has gradually fallen to the extent that the downstream factories can withstand, and most of them are mainly based on low-replenishment, and the market low-cost supply is still acceptable.

It is expected to be short-term, interval consolidation, and active shipments.
