• Market price trend of polyvinyl alcohol on April 15th

  2024 / 04 / 15

  On April 15th, the mainstream market negotiations for polyvinyl alcohol 1799 # reached 11800-12800 yuan/ton in cash, for polyvinyl alcohol 2699 # reached 12300-13500 yuan/ton in cash, for PVA 1788 # reached 12300-13500 yuan/ton in cash, for PVA 2488 # reached 13300-14700 yuan/ton in cash, and for PVA resin 2099 # reached 12000-13300 yuan/ton in mainstream market negotiations.The supply side situation shows that the acetic acid market is relatively strong and upward this week. At the beginning of the week, the price of acetic acid fell to a low level, leading to an increase in downstream demand and a bullish attitude among enterprises. As the market trading atmosphere improves, the price of acetic acid continues to rise. As of March 29th, the average market price of acetic acid was 3100 yuan/ton, an increase of 3.33% compared to March 25th. The recent increase in demand in the calcium carbide market has become the main factor contributing to the price increase. With the update and implementation of PVC maintenance plans, the expected supply of calcium carbide is expected to increase significantly. As of April 10th, the benchmark price of calcium carbide has risen to 3016.67 yuan/ton, an increase of 0.56% compared to the beginning of this month. Overall, the recent trend in the cost of polyvinyl alcohol has been warm, with slight positive support in the market. Despite stable supply side support, the overall weak demand situation has not significantly improved. Intermediaries prepare goods according to demand, while downstream suppliers purchase goods on demand, resulting in a mediocre trading atmosphere.

• Price Analysis of PVC Paste Resin Industry Chain in 2023

  2024 / 01 / 15

  Polyvinyl chloride resins are mainly divided into general resins and paste resins according to their uses: General resins (G resins) are resins that are processed and formed into dry or wet powders by mixing with normal amounts of plasticizers or additives; Paste resin (P resin) is usually used in conjunction with plasticizers to form a paste resin; In addition, there is PVC blending resin, which is a type of PVC resin that replaces some of the paste resin by blending when preparing PVC plasticizers. The main production methods of PVC resin include suspension method, bulk method, lotion method, solution method and micro suspension polymerization method. From a worldwide perspective, suspension method is the main production method of PVC general resin, while the production method of PVC paste resin is lotion method and micro suspension polymerization method. Due to different production processes, the capacity of the two resins cannot be converted to each other. In 2023, the prices of various products in the PVC industry chain have fallen compared to previous years. In the second half of 2023, the prices of the industrial chain have all risen to varying degrees. The price trends of PVC and PVC paste resin are relatively consistent, mainly due to the psychological impact of PVC futures on the spot price of PVC paste resin in recent years. PVC paste resin has a slight lag, but under the influence of futures, the price is close to the spot price trend of PVC. The price of raw material calcium carbide is negatively correlated with the trend of downstream PVC and PVC paste resin in the first half of this year, mainly due to the significant lag effect of the two downstream products. The rise and fall of calcium carbide is ahead of PVC and PVC paste resin, and the two only have

• Analysis of supply and demand, scale and current situation of China's carbon black industry in 2023: The industry has shifted from high-speed development to high-quality development stage

  2023 / 12 / 26

  Carbon black is an amorphous carbon with a very large surface area, ranging from 10-3000m2/g, and particle size of 10-100nm. Carbon black is a type of carbon element that exists in the form of nanoscale particles and amorphous carbon. It is a product of incomplete combustion or thermal decomposition of organic compounds (natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. Carbon black is one of the earliest developed, applied, and currently produced nanomaterials by humans, and is listed as one of the 25 basic and fine chemical products in the international chemical industry. The production process of carbon black can be divided into two categories: "incomplete combustion method" and "thermal cracking method". Incomplete combustion method (thermal oxidation decomposition method) includes oil furnace method, gas furnace method, spray method, lamp smoke method, trough method, drum method, and mixed gas method; The hot cracking method includes hot cracking method, acetylene method, and plasma method. Among them, the oil furnace method has the characteristics of multiple process adjustment methods, high thermal energy utilization, low energy consumption, and low cost, making it the main production process for carbon black. SP and Koqin black are prepared by the oil furnace method, while acetylene black is produced by the acetylene thermal cracking method. Policies related to China's carbon black industry From the current situation of China's automobile industry, based on the existing foundation of the automobile industry and the promotion of national strategic emerging industries and energy-saving and emission reduction regulations, through solid promotion and key breakthroughs during the 13th Five Year Plan period, it is possible to form low-carbon, information-based, a
