Last week, the supply of liquid ammonia decreased and the price rose

Last week, the domestic liquid ammonia Market showed mild performance, with Hebei and Shandong regions rising in varying degrees from the beginning of the week to the middle of the week. According to the monitoring of the business agency, the rise in Shandong was 0.52%, and the mainstream market quotation was 3000-3200 yuan / ton.

 

The price of liquid ammonia in Shandong has risen slightly. The supply of large factories is stable, the unit is running normally, and the inventory pressure is lower than that at the end of last month. Due to the weak performance of domestic urea, the relatively considerable price difference shows that liquid ammonia is stronger than urea, especially due to the limited production in some domestic regions, and the operating rate is reduced, which brings certain support to the supply To form a stable support. In terms of the downstream, the demand for agricultural fertilizer in the current off-season is slightly insufficient, which is also the main reason why the price of liquid ammonia has not been greatly pushed up.

 

In other regions, the price of liquid ammonia in Shandong has been adjusted by Shandong large factory this week, and the outflow of ammonia from Shandong is not as large as expected, so the impact on Hebei region is not obvious, so the price of manufacturers in Hebei has also increased slightly. The increases were all around 50 yuan / ton. At present, the Cangzhou unit of a plant in Hebei still produces a small amount of liquid ammonia, so the pressure is not big. This is also an important factor to balance the supply and demand of the region. The liquid ammonia quantity in the region basically maintains a balance between supply and demand, and the current price is between 3050-3200 yuan / ton. In other regions, such as northeast China, due to the continuous maintenance of large factories in this region, the supply of goods is in short supply, and the price of liquid ammonia has increased significantly. The price of liquid ammonia has already exceeded 3200 yuan / ton.

 

In the future, the business agency believes that the liquid ammonia market may continue to push up this week. On the one hand, prices in Shandong and Hebei have remained firm for some time, and the supply pressure is not big. On the other hand, some orders from Northeast China may be accepted in the future, and the ammonia quantity in the region may decline, which may lead to an upward price.

Potassium chloride price rises this week (12.07-12.11)

1、 Price trend

 

The comprehensive price of potassium chloride is temporarily stable this week. The average price of potassium chloride mainstream comprehensive quotation this week is 2160 yuan / ton. Overall, this week’s potassium chloride market temporarily stable, December 11 potassium chloride commodity index was 68.57.

 

2、 Market analysis

 

This week, the quotation of mainstream manufacturers of potassium chloride is temporarily stable: the ex factory offer of Qinghai Salt Lake potassium chloride at the weekend is 2020 yuan / T, which is temporarily stable compared with the beginning of the week; the quotation of Anhui Badou potassium chloride distribution at weekend is 2300 yuan / T, which is temporarily stable compared with the beginning of the week. The actual turnover of potassium chloride market this week is not good. Overall, the main contradiction in the market is that supply exceeds demand, the trading atmosphere is cold, the downstream procurement is mainly on demand, the overall inventory is low, the purchasing market momentum is low, and the domestic potassium chloride market is stable.

 

3、 Future forecast

 

In the middle of December, the overall trend of potassium chloride market may fluctuate slightly. The market of potassium chloride is facing the pressure of three mountains, namely, the large stock in Hong Kong, the weak demand and the downward trend of international prices. Therefore, the main contradiction in the current market is that supply exceeds demand. Potassium chloride analysts of the business club believe that the short-term potassium chloride market is mainly composed of high-level consolidation under the influence of supply and demand and raw materials.

Lack of raw material support, propylene glycol began to decline at the beginning of the month

 

From the beginning of December 2, the latest offer price of domestic industrial grade propylene glycol fell sharply, mainly due to the lack of cost support from raw materials. Since the end of November, propylene oxide, the raw material, has been in a continuous decline. With the continuous weakening of cost support, propylene glycol factories have successively reduced the ex factory price of propylene glycol by 1000-2000 yuan / ton. In this week, the market trend of propylene oxide was stable, and the support for propylene glycol was improved compared with the previous period. However, in terms of demand, the downstream wait-and-see mood was heavy, the trading atmosphere was cold, and the operators were cautious in taking and replenishing goods. The price of propylene glycol Market rose and fell in a mixed manner, and the overall decline was more. As of December 11, the factory price of domestic industrial grade propylene glycol was 10666 yuan / ton, compared with December 6 Compared with the daily price, the average price was reduced by 600 yuan / ton, with a weekly decrease of 5.33%; compared with December 1, the average price was reduced by 2000 yuan / ton, with a decrease of 15.57% within ten days.

 

On the upstream side, on the first day of the month, the domestic propylene oxide market was stable after a sharp decline, and the current market was stable. As of December 10, the reference price of propylene oxide was 17300.00 yuan / ton, up 0.7% compared with December 1 (17166.67 yuan / ton).

 

After the lack of demand, the market does not rule out a small decline

 

Since December, the downstream demand of industrial grade propylene glycol in China has been flat, with few new orders. At present, the inventory is expected to rise. Therefore, business agency propylene glycol data analysts believe that in the short term, propylene glycol market will continue to explore slightly.

Supply expected to shrink, market price of bromine firmed up

1、 Price data:

 

According to the data monitoring of the bulk list of business associations, affected by the expected decline in supply, the domestic bromine market has been strong and upward. As of December 10, the average price in Shandong was about 33000 yuan / ton, up 1.37% compared with the beginning of the month and 6.64% higher than the same period last year.

 

2、 Cause analysis

 

Affected by the cold weather, the bromine production enterprises in North China began to reduce the burden, and the spot supply of bromine declined. Weifang, the main production area, is about to enter the shutdown period. The manufacturers’ shipping intention is flat. In addition, the overall inventory of the industry is low, and the enterprises have a good attitude to stand up for price. The downstream market does not have a high acceptance intention of bromine high price. The supply and demand game is playing. At present, the mainstream bromine enterprises offer about 33000-33500 yuan / ton 。

 

On the upstream side, the domestic sulfur market has been stable for a while, and the sulfur market has been running steadily. There is no low-cost shipping intention for the holders. At present, the downstream demand is stable and the shipment is smooth, and the procurement is mainly based on demand. The future market pays attention to the follow-up of the downstream, which is about 1010 yuan / ton. In terms of sulfuric acid, the price of raw materials has been running at a high level recently, and the cost support is good. In addition, some sulfuric acid manufacturers do not have enough operation, The load is reduced and the supply of sulfuric acid is tight, at present, it is about 437 yuan / ton; the price of caustic soda is temporarily stable, the mainstream ex factory price of 32% caustic soda is 400-530 yuan / T, the downstream purchasing demand is general, there is a certain conflict with the current caustic soda price, and it is expected that the follow-up or narrow range of caustic soda will be weak. The main downstream flame retardant market of bromine started production generally, but there was insufficient demand for bromine purchasing, the overall intention of receiving goods was flat, and the high price of bromine was obviously contradicted; the start-up of pharmaceutical and pesticide intermediates and other industries was flat, and the demand side generally supported the bromine price.

 

3、 Future forecast

 

The bromine industry analysts of the business society believe that, with the reduction of supply expectation, the domestic bromine market will continue to be strong. Most of the production enterprises prepare for storage during the long shutdown period. The shipping intention is flat and the sentiment is warm. However, the downstream market generally receives goods, and sporadic bulk orders are mainly traded. The supply and demand game is playing. It is expected that the bromine market will still be strong in a short period of time.

The transaction volume of methanol market in central Shandong was stable to 2150 yuan / ton, and the external goods negotiation was delivered to spot exchange at 2030-2050 yuan / T, slightly up. The reference price of Shandong methanol in Lubei market is 2060 yuan / ton, which will be delivered to spot exchange. Methanol market up and down, limited support for formaldehyde.

 

Recently, due to the impact of environmental control, the traditional downstream wood board enterprises started to tighten up, and the demand for formaldehyde was weakened, thus maintaining the rigid demand procurement. Formaldehyde market shock consolidation.

 

Recently, the upstream raw material methanol market has been stable and small movements. Some downstream factories have stopped production due to the impact of a new round of domestic environmental control and control, and the formaldehyde factory is under great pressure to ship. Therefore, formaldehyde analysts of chemical branch of business agency predict that the formaldehyde price in Shandong Province will fall mainly in the near future.

Recently, the rise of domestic LNG has returned, and the price has been rising continuously, with a one-day increase of 17% on the 7th. Since December, the increase has exceeded 23% in just a few days, higher than the same period last year. At present, the prices of Inner Mongolia, Shaanxi, Ningxia, Shanxi and other places have broken through the 5000 yuan mark, and the market prices have risen in a straight line, and the import gas has also been actively pushed up, so the market sentiment has been boosted. The continuous rise of liquid price in this round is mainly due to the cold weather and the substantial increase of urban fuel demand. In addition, there are still production stoppages and gas restrictions in some areas. The regional supply is tight and there is no obvious improvement. The manufacturers support the prices and the liquid prices continue to rise. At present, there are a lot of rainy and snowy weather, traffic is not smooth, some liquid factories are under pressure to ship, the price is slightly back, and the downstream is also tired. However, the demand side and supply side support strongly. In the short term, the LNG market is strong, and there are still upward expectations, but the increase may be narrowed.

PA66 prices strengthened in early December

Price trend

 

According to the data from the business club’s bulk list, the domestic PA66 market remained firm at the beginning of December, with various models of products slightly adjusted. As of December 4, the average offer price of PA66 medium viscosity injection molding class sample enterprises was about 29400 yuan / ton, with a weekly decrease of 1.34%.

 

In terms of adipic acid upstream of PA66, affected by the higher price of pure benzene last month, the domestic adipic acid market generally continued to rise. In December, the current upstream pure benzene still rose, supporting the cost of adipic acid. In terms of supply, the operating rate of adipic acid manufacturers has remained stable recently, and the market supply is relatively sufficient. Due to the increase of cost pressure at the beginning of the month, the manufacturer has certain shipping pressure. In the later stage, the current market fundamentals are OK, but the business community is worried about the weakening demand brought about by the decline of downstream operating rate in winter. Adipic acid market is expected to follow the upstream trend.

 

Adipic acid on the cost side of PA66 support is acceptable, PA66 market rose a lot last month, the beginning of December high hold firm. In terms of supply, Zhejiang Huafeng’s operating rate has increased recently, but the overall operating rate of domestic production lines is not high, and the factory has no pressure of accumulating stocks for the time being, and the mentality of supporting the market is still strong. The situation of spot shortage in domestic spot market has not improved. Moreover, the new products are still mainly supplied to the old customers under the contract, which aggravates the situation of tight supply in the field, and the situation that the merchants have no goods sometimes occurs. Following the price increase letters issued by BASF, DuPont and aoshengde, Toray of Japan also issued a price increase notice, which continued to improve the prices of PA66 spot and related raw materials in the industrial chain. The replenishment operation of downstream factories is biased towards rigid demand, and the high price of PA66 also increases the pressure of downstream cost, and the operation is mainly oscillatory at the beginning of the month

 

Business agency analysts believe: PA66 in early December domestic market trend temporarily stable. The price of upstream products is high, which can support the cost of PA66. Downstream goods just need to operate, high price goods have conflict. But the spot is in short supply, the terminal passively follows up, the current demand is OK. At the beginning of the month, new products were cautiously low, and it is expected that the market price of PA66 will continue its high and strong trend in the short term.

In December, the market trend of butanone market has not changed significantly, and the overall situation is weak and stable. The market quotation of butanone in some regions has been reduced by 100-300 yuan / ton. At present, the overall stock of domestic butanone market is not much, but the downstream demand is much colder than that in November, and the support of new orders is insufficient, mainly due to the reduction of export orders and the general trading atmosphere of the market. Shandong Province: the reference price of butanone is 7500-7700 yuan / ton, which is 200-300 yuan / ton lower than that at the end of November. Jiangsu Province: the reference ex factory price of butanone is 7400-7600 yuan / ton, which is 100-200 yuan / ton lower than that at the end of November.

Brent crude oil futures market prices rose, with the settlement price of main contracts at $48.25/barrel, up $0.83. Oil prices rose on Wednesday as the approval of a vaccine in the UK boosted hopes for a recovery in fuel demand, and the market generally expected OPEC + to continue at the scale specified in the current production reduction agreement.

 

Insufficient demand for butanone will continue to weaken

 

At present, there are not many stocks in the plant, export orders are weak, the downstream demand is insufficient, and the attitude of the operators is not good. The butanone data analyst of the business society believes that the butanone market may continue to weaken in the short term, and more attention should be paid to raw materials and demand changes in the future.

Polyglutamic acid

The market of refrigerants is getting warmer, and the prices of various models are rising actively

1、 Price trend

 

Polyglutamic acid Pharmaceutical(medicine) grade

As of December 2, the average price of refrigerant R22 was 14333.33 yuan / ton, up 2.38% compared with the previous trading day, 3.61% higher on a month on month basis, and 11.34% lower than the same period last year, according to the monitoring of bulk data of the business agency.

2、 Market analysis

 

R22, since the beginning of November, R22 market continued to warm up, the price rose steadily, and the price trend continued to rise on the 2nd day. Many enterprises raised 500-1500 yuan / T, up about 3% in the past month. Some enterprises were short of goods and closed the offer. This round of R22 price continued to rise, mainly due to the raw material upward and quota support, especially raw material chloroform, increased by about 30% in the month, giving R22 a strong support. However, there is no hope of boosting the demand side, the domestic and foreign trade and the terminal market are not good, and it is difficult to make a significant change in the off-season. However, supported by the favorable cost and quota, the market returns to the seller’s market, so it is easy to rise and difficult to fall in the future. As of the 2nd day, the prices of mainstream manufacturers in refrigerant R22 market are around 14000-16000 yuan / ton.

 

R134a: since November, the market of R134a has been relatively stable, and has been rising recently. On the 2nd day, the price of R134a has risen sharply. Many enterprises have raised 500-1500 yuan / ton, up about 5% in the past month. The rising price of R134 is mainly due to the rising prices of raw materials hydrofluoric acid and trichloroethylene. The strong cost support has boosted the price of R134a. The automotive refrigerant is in the stage of stock preparation, and the demand is improved, but there is not enough good expectation. At present, R134a is a concentrated export period. However, the international situation is still uncertain, and the export end has not improved significantly. In addition, the operating rate of manufacturers is improved, and the warehouse is discharged As of the 2nd day, the prices of the mainstream manufacturers in the R134a market were around 16000-16500 yuan / ton.

 

Polyglutamic acid cosmetic grade

As for the raw material hydrofluoric acid, on December 2, the mainstream price of domestic anhydrous hydrofluoric acid manufacturers was 8000-8500 yuan / T. the ex factory price of domestic manufacturers was temporarily stable. The domestic hydrofluoric acid manufacturers had a general operating rate, and the supply of goods on site was normal, which was affected by the stable price of fluorite. However, the demand of the downstream refrigerant industry was poor, and the on-site purchase was mainly on demand. It was expected that the on-site price would remain volatile in the future.

 

The price of chloroform and methane chloride Market in Shandong Province rose. The mainstream quotation of dichloromethane market was 3320-3420 yuan / ton, and the mainstream quotation of chloroform market was about 3650 yuan / ton. At present, the spot supply of chloroform market in China declined slightly, which stimulated the demand of downstream and traders. The overall purchase increased. The inventory pressure of chloroform enterprises was not big, and it is expected that in a short period of time, the supply of chloroform in the domestic market declined slightly The price of methyl chloride is stable. Pay attention to the change of liquid chlorine price of raw materials.

 

3、 Future forecast

 

According to the refrigerant analysts of the business agency, the raw materials are rising at present, and there is no intention of callback. The cost support is strong, and the prices of various types of refrigerants are actively adjusted. It is expected that the prices of R22 and R134a are easy to rise and difficult to fall in the short term, and the prices may continue to rise.
