PriceSeek analysis of propylene, with a long-short score of 1: Shandong Haike Chemical's propylene quotation was raised by 40 yuan/ton to 6,420 yuan/ton, and the 60,000-ton/year plant is operating smoothly with normal shipments. This indicates stable supply in the spot market, but demand may be strengthening or cost factors are driving prices upward.
