According to the data monitored by SunSirs, the PP market maintained a narrow rise on December 15, and the spot prices of various brands continued to rise today. According to the price of SunSirs, the mainstream offer price of T30S (wire drawing) from domestic manufacturers and traders is about 8150 RMB/ ton. The upstream propylene market has sufficient supply, the demand continues to be weak, and when the overall chemical industry turns weak, the price is easy to fall but difficult to rise, the downstream follow-up is slow, and the cost and demand side support PP is general. Recently, PP went to the warehouse smoothly, and the mentality of on-site sellers has been strengthened. However, the recent production line pushes up the supply, and it is expected that China PP ptice will be difficult to have a big rise in the short-term future when the demand remains at a low level.
