According to the data monitored by SunSirs, the PP market was sorted and operated on December 8, and the spot prices of various brands rose and fell yesterday. According to the price of SunSirs, the mainstream offer price of T30S (wire drawing) from domestic manufacturers and traders is about 8,170 RMB/ ton. The upstream propylene market has sufficient supply and the downstream demand is weak. It is expected that the short-term propylene market will maintain a volatile downward trend. Propylene is weak in stability and generally supports PP. Due to insufficient follow-up on the demand side of PP and the rising resistance of crude oil, it is expected that PP pirce in China will be difficult to rise in the short-term future.
