Fluorine chemical raw materials: analysis of the third quarter

Introduction: In the third quarter of 2023, the prices of fluorite powder and anhydrous hydrofluoric acid have stopped falling and risen. Tight supply and rising costs are the main factors supporting prices. In the fourth quarter, when fluorine chemical companies have good expectations for winter storage of raw materials and terminal refrigerant prices, the market still has room for strong operation.  The market for fluorochemical raw materials rebounded after falling in the third quarter of 2023. At the beginning of the third quarter, the terminal refrigerant market demand was weak, and prices fluctuated and declined. This was transmitted from the bottom up to the raw material market, and prices continued to decline. Since mid-to-late August, under the influence of the continued tight supply of fluorite powder, downstream fluorine chemical companies have been stocking up on raw materials in advance. As the demand for fluorite powder continues to increase, prices have taken the lead in rising, and the driving force of raw materials on the market has increased. Promote the improvement of the industrial chain market from top to bottom.The upward trend in the third quarter has ended, and the market is also expected to be better in the fourth quarter.At the end of September, the fluorine chemical raw material market continued to trend upward, and the market environment was still supportive of prices. On the one hand, from a supply perspective, fluorine chemical companies have winter storage of raw material fluorite powder at the end of the third quarter and the beginning of the fourth quarter. The monthly procurement volume will increase to more than 10,000 tons to prepare for winter production. Driven by demand, the price of fluorite powder will increase. There has been a significant increase. Judging from the supply and demand situation in the fluorspar market during the year, mine operations are low. Affected by the shortage of ore, the operation of dressing plants is less than 40%, and the inventory is small. It is common to determine sales based on production. It is expected that the tight supply of fluorspar powder will not be alleviated in the fourth quarter, and prices are still likely to continue to rise in the future, perhaps until around November. From the perspective of anhydrous hydrofluoric acid, due to the tight supply of raw material fluorite powder, the start-up of some production companies was restricted at the end of the third quarter, and the market start-up remained at around 55%. The market supply was tight, and production companies were obviously hesitant to stock. Coupled with the increase in the price of fluorite powder, the market support for anhydrous hydrofluoric acid is relatively strong, and it is expected to have a synchronized upward trend with the market price of raw material fluorite powder.On the other hand, as of mid-September, the price of downstream refrigerants has been rising steadily, and the refrigerant HFC-134a has continued to hit new highs in the new year. At the same time, as the implementation date of HFCs quotas in 2024 approaches, the overall situation of limited supply in the future market will be determined. Industry players are full of expectations for a better market, and the low-price reluctance to sell at the production end is obvious. The bullish expectations in the HFCs market will provide positive support to the market ahead of the implementation of quotas. With the psychological expectation that the terminal market will improve, it will also provide good support for the raw material market, and the market outlook is still optimistic about the fourth quarter market.

Market briefing

The price of fluorite is still at a relatively high level, and the increase in raw ore mining rate is limited. Winter storage is approaching, and the supply of wet powder is tight in some areas. The market prices in East and South China are on the high side. The spot supply of fluorite powder for acid use in the northern and southern markets is still divergent. Single incremental slowdown. The main major manufacturers in the downstream anhydrous hydrofluoric acid industry mostly executed pre-contract orders. The prices of new bulk orders increased again. The prices of raw materials continued to increase. The profits of hydrofluoric acid companies were once again compressed. Some companies moderately lowered their start-up due to the high level of raw materials. According to statistics , the operating rate was reduced by 1% in mid-September compared with the beginning of the month. At this stage, the overall supply of the market is tight, and some bulk orders have increased. Terminal demand is expected to rebound in the future. The refrigerant quota will be issued soon. The bullish mentality of the market has not diminished, and there will be further increases in the future. expected.Trading in the aluminum fluoride market is proceeding in an orderly manner. The bidding prices of downstream electrolytic aluminum companies have increased. Fluorite speculation has increased. Profits of more than 10,000 yuan for hydrofluoric acid have increased. Aluminum fluoride trading volume has increased slowly. The spot price is tight. Fluorosilicic acid resources have increased slightly. Nervous, regional supply is tight. The price of sodium fluorosilicate is running weakly. In the second half of the year, sodium fluorosilicate gradually enters the peak season. However, the market demand has not yet seen a positive trend. The mentality of the industry is cautious and the short-term market is mainly stable. The output of sodium fluoride is limited, the spot stock on the market is relatively scarce, and the raw materials continue to boost, the support is sufficient, and the market is strong today. The market demand for ammonium fluoride is weak, and companies are rationally lowering prices. Due to weak terminal demand, the ammonium fluorosilicate market has eased supply tension, raw materials are stable, and supply and demand are balanced. The current market opening rate of potassium fluoride is low, and industry losses are common.The PTFE market continues to remain at a low level, raw materials are gradually rising, and cost support is significant. The start-up of domestic enterprises has increased, and many new production capacities have been released during the year, increasing pressure on the supply side. Recently, the market inventory has declined due to the decline in construction. Currently, the fluorine chemical raw material R22 is recovering, the price of hydrogen fluoride is increasing, and the cost support is rising. There is a large gap between the offer and transaction in the PTFE market. The suspended medium particle market, dispersion resin market, and emulsion prices are actually due to quality differences. Transactions are low. Under demand constraints, the polytetrafluoroethylene market is still difficult to improve, and was mainly depressed during the year. Hexafluoropropylene is mainly due to the expected enterprise maintenance in September and the recent increase in raw material costs.

Fluorite powder market morning reminder (20230911)

1. Mainstream marketFluorite powder prices continued to rise last week, and tight supply was the main factor supporting the price increase. The support of cargo holders' sentiment of being reluctant to sell goods also benefits the market to a certain extent. Downstream companies all reported low inventories and there is still support on the demand side.2. Key factors affecting current market price changesDemand: Some downstream companies have low raw material inventories this week, and there is still demand for external mining of fluorite powder. The positive support on the demand side is still there.Supply: The start-up of the dressing plant during the week is expected to have limited fluctuations, and cargo holders have insufficient intention to ship. The tight market supply situation is likely to continue.Downstream prices: The prices of anhydrous hydrofluoric acid and aluminum fluoride are expected to improve this week, and the price of bulk orders is likely to rise, which will provide good support for the price of fluorite powder.3. Trend predictionThe prices of downstream anhydrous hydrofluoric acid and aluminum fluoride are expected to improve this week, and downstream companies are still in need of replenishment of raw materials, so it is difficult to increase supply. It is expected that the price of fluorite powder will still remain high.
