Price Trend

According to the data of the business associations’list, the domestic PA66 market continued to be weak in late September and the price weakened. As of September 27, the average offer price of PA66 medium viscosity injection molding grade mainstream was about 23250.00 yuan / ton, basically maintaining the level of last weekend.

Analysis of influencing factors:

The market of adipic acid in upstream PA66 has been adjusted mainly after a slight recovery in recent years. The adipic acid market has entered a stage bottom. The bottom-finding process has basically come to an end, and the market has stabilized, but the increase is very limited. And the market climate is still slightly rigid, distributors are mainly active in delivering goods, the market has some room for concessions, and there is still no centralized purchasing behavior. The main reason why adipic acid prices stopped falling and recovered steadily was that the cost side boosted the price of upstream pure benzene, which had risen by more than 15% since mid-August, according to business associations. On the supply side, the market supply is still abundant, and many distributors say that the inventory pressure is high, the plant start-up rate is high, and the market inventory and manufacturer inventory have increased. In terms of demand, downstream demand is relatively weak. The traditional “Golden Nine” market has not arrived as scheduled this year. The downstream start-up rate is still slightly insufficient. The downstream general depression is the main reason why adipic acid is difficult to get rid of the weak market. Adipic acid market may continue to maintain a narrow adjustment pattern in the short term. Spot supply in domestic PA66 market is abundant in late September. Recent news points to the expectation of further increase in supply, which is not conducive to easing the contradiction between supply and demand. Downstream factories just need to take delivery, demand has not improved and continued to weaken. The market buys gas insufficiently, the trader wait-and-see mentality is heavy. Businessmen have reduced their public quotations and made it difficult to deal with them in detail. The overall market trend is weak, and domestic PA66 is still weak and persistent in late September.

Future forecast:

Business analysts believe that: late September domestic PA66 market weakness adjustment. Upstream adipic acid transverse plate adjustment has limited cost support for PA66. At present, the supply is abundant, and the contradiction between supply and demand is still the main contradiction in the domestic PA66 market. The enthusiasm of downstream reserve is not high, and the strategy of just taking goods is adopted. The market is short of gas, the traders are passive and wait-and-see, and the open quotation of the merchants is reduced. It is expected that PA66 will continue its disadvantaged consolidation in the near future.

At the beginning of the week, the guideline price of Shanghai Cosco’s founding factory was not clearly announced, but the market was informed that the guideline price had dropped significantly. On-site negative atmosphere spread, the market low turnover increment. With the continuous fermentation and spread of crude oil incidents, the mentality of the operators has been greatly affected. The downstream terminal customers actively enter the market to collect goods, and the holders actively maintain the shipment status based on the accumulated inventory. Later, with the unexpected greening of crude oil, the active atmosphere of the market was instantly extinguished, and the purchasing volume of the downstream for a period of time was also completed. The positive atmosphere of the market transaction was reduced. However, in view of the previous large volume of shipments, the stockholder relieved the inventory pressure and reluctantly sold. September should be in the peak season of traditional northern thermal insulation enterprises, but this year’s “Golden Nine” has not been quiet due to the impact of previous environmental inspections and Sino-US trade wars.

On the market side, as of Friday (9.20), the North China Polymerized MDI market was deadlocked, the overall atmosphere in the field was low, the turnover was short, and the vendors’offer was stable and low-priced.

South China Polymerization MDI market is weak, the atmosphere is light, business is not smooth, business offer is stable, low price is the main price. At present, the quotation of barreled goods with tickets in Shanghai refers to 11600-11700 yuan/ton, and the quotation of PM200 barreled goods with tickets in Shanghai refers to 12600-12800 yuan/ton.

Industry chain: raw materials, pure benzene: This week, the price of pure benzene rose. Saudi oil field was attacked, crude oil surged early in the week, driving FOB Korea pure benzene to rise more than $50 per ton, and East China pure benzene offer also exceeded 6000 yuan per ton. Sinopec’s listing rose to 5900 yuan/ton in time. However, as the industry expects Saudi crude oil facilities to recover soon, this round of increase is only due to short-term psychological support, difficult to sustain, and the downstream has established stockpiles of raw materials, so there is no willingness to pursue this round of rise downstream factories, trading only occurred in the hands of traders. With Saudi Arabia’s announcement that crude oil will return to its pre-attack production level by the end of September and that Saudi oil exports will not decrease in September, supply risk concerns have eased and international oil prices have plunged. After losing the good support of crude oil, the market mentality changed, and the internal and external markets subsequently fell.

However, with the rebound of crude oil, the price of pure benzene rationally returned to the vicinity of 5900 yuan/ton. On-site pure benzene spot is tight, the market is still strong. This week, the average tender price of pure benzene in Jinling, Shandong Province, rose 148 yuan from last week, and aniline cost support is strong. At the same time, Tianji 9.15 accidental parking, a small amount of goods only for core customers, resulting in a large number of downstream users such as Henan to find goods in Shandong, Shandong enterprises aniline plan, low inventory, rising prices, and began to limit delivery. In the East China market, Yangnong plant only maintains normal operation and has no product output for the time being. In addition to the main supplier contract customers, Nanhua’s main spare shipments release a small amount of goods on the market. The sales pressure of East China enterprises is low, and the price keeps rising in North China.

3. Future Market Forecast

It is expected that near the end of the month, in addition to the small amount of goods on hand, agents are reluctant to sell, and market prices are strong. Despite the limited downstream picking efforts, the trend of price decline is not obvious under the support of cost. Analysts of business associations aggregate MDI expect that next week domestic aggregate MDI market price range shocks dominate. Pay close attention to the price guidelines and supply policies of Shanghai factories.
