According to the Commodity Market Analysis System of Shengyi Society, as of the 25th, the price of ethyl acetate was 5386.67 yuan/ton, a decrease of 0.68% compared to the price of 5423.33 yuan/ton on August 18th, and a decrease of 1.10% from the beginning of the month. The supplier’s inventory has slightly increased, downstream demand continues to be weak, market transactions are average, and the ethyl acetate market continues to operate weakly.

The utilization rate of domestic ethyl acetate production capacity has slightly increased, and the market inventory has increased. Enterprises maintain active shipment, but downstream market entry enthusiasm is not high. A small amount of low-priced purchases are sought, and market consumption inventory is limited. The domestic acetic acid on the raw material side has fluctuated, and cost support is insufficient. Enterprises follow the market, and the price of ethyl acetate is weak and fluctuating.
In the future, the shipment of ethyl acetate enterprises is average, downstream demand consumption is slow, and the market fundamentals are weak. Recently, some areas of raw material acetic acid have been operating strongly, which has boosted the mentality of ethyl acetate. It is expected that the short-term market for ethyl acetate may rise slightly, and specific attention should be paid to changes in supplier equipment and downstream follow-up.

This week, the price of plasticizer DOP has stopped falling and rebounded

According to the Commodity Market Analysis System of Shengyi Society, as of August 25th, the DOP price was 7759.16 yuan/ton, which first fell and then rose compared to the DOP price of 7759.16 yuan/ton on August 15th. This week, the operating load of DOP enterprises has slightly decreased, the production of plasticizers has remained stable, and downstream demand is unlikely to improve. The intention of DOP procurement inquiries is flat, and the improvement in DOP demand transactions is limited. The price of raw material isooctanol fluctuated and fell, the price of phthalic anhydride fluctuated and rose, and the cost support of plasticizers slowed down. The stable supply has led to a decrease in costs, and the price of plasticizers has stopped falling and stabilized this week.

According to the Commodity Market Analysis System of Shengyi Society, as of August 25th, the price of phthalic anhydride in neighboring countries was 6333.33 yuan/ton, which first decreased and then increased compared to the price of 6300 yuan/ton on August 15th, with an increase of 0.53%; Compared to the price of 6233.33 yuan/ton quoted on August 20th, the price of ortho benzene has fluctuated and increased by 1.60%. The price of ortho benzene is stabilizing, the price of industrial naphthalene is rising, the cost of phthalic anhydride is increasing, the operating rate of phthalic anhydride equipment is consolidating at a low level, and the cost increase combined with weak supply and demand has led to a rebound in phthalic anhydride prices this week. The price of raw material phthalic anhydride has risen, and the cost of plasticizers has increased. This week, the downward pressure on the price of plasticizer DOP has weakened.
Future expectations
According to the data analyst of Shengyi Society’s plasticizer products, in terms of cost, the price of isooctanol has fluctuated and fallen, while the price of phthalic anhydride has rebounded and risen, and the cost of plasticizer DOP has stopped falling; On the supply side, the operating capacity of plasticizer enterprises has slightly decreased, the production of plasticizers has remained stable, and the supply of plasticizers is sufficient; In terms of demand, the overall economy is sluggish, coupled with anti competition and the elimination of outdated production capacity, resulting in weak downstream demand. Overall, the weak supply and demand, coupled with the stabilization of costs, are expected to lead to a consolidation of the price of plasticizer DOP in the future.
