In the first week of March, the price of domestic PVC paste resin fluctuated significantly in a narrow range, mainly due to the impact of fundamental and macro changes. However, the overall market expectation in March is still uncertain, and the follow-up may still be cautious. In the first week of March, the price of domestic PVC paste resin fluctuated significantly, and the price fell first and then increased slightly. The price decline at the beginning of the week was mainly due to the weak...
Titanium dioxide is an important fine chemical raw material. Its chemical composition is titanium dioxide (TiO2). It is a white inorganic pigment with wide application and great market demand. Titanium dioxide products are divided into two categories: one is rutile titanium dioxide, which has strong light resistance and weather resistance, and is mostly used in the production of outdoor coatings and products; The other is anatase titanium dioxide, which has worse light resistance than rutile....
Titanium dioxide has always been the product with the highest supply and demand in the titanium industry, and its scale has been increasing in recent ten years. However, from the perspective of supply and demand, the growth rate of output is significantly higher than that of apparent consumption, mainly due to the significant growth of exports and the diffusion of global titanium dioxide production to developing countries. With the continuous maturity of titanium dioxide production technology...
Introduction In February, due to certain changes in market participants' expectations for the follow-up market, PVC futures prices rose and fell significantly, and the spot price fluctuated with it. At present, the overall fundamentals of PVC spot are weak. It is expected that the short-term price may continue to fluctuate in a narrow range. However, with the development of both ends of supply and demand, it is expected that the subsequent market fundamentals will gradually strengthen. This...

At the beginning of this month, India's anti-dumping policy (add) on PVC imported from China and the United States officially expired. At present, no new policy has been announced. For China, the vacuum period of anti-dumping policy is the key period to expand exports. As the re export volume is not large, the expiration of the anti-dumping policy will bring the marginal increment of PVC export; Export increment depends on the length of time the policy window is opened and the strength of PVC...

In January, the start-up of PVC glove products enterprises was slightly weak. Near the eve of the Spring Festival, some terminals prepared raw materials inventory, and the overall transaction atmosphere of PVC paste resin glove materials was acceptable. According to the start-up monitoring of 20 PVC glove sample enterprises, the start-up load of domestic PVC glove products enterprises decreased slightly in January, 30-60% of large glove products enterprises started, and the start-up of medium...
Introduction Before the Spring Festival holiday, the overall atmosphere of the domestic PVC paste resin market was acceptable, and most enterprises' inventory fell to a low level with a good mentality; On the first day after the festival, PVC paste resin enterprises did not offer much on their own initiative, and some closed their plates to wait and see, with sporadic attempts to boost the small rise. Two weeks before the Spring Festival holiday, the price of domestic PVC paste resin hit the...
Industry chain introduction: polyvinyl alcohol and Vinylon Industry is a sub industry of the chemical industry. Polyvinyl alcohol (PVA) is a high molecular polymer, which is made by polymerization and alcoholysis after the synthesis of vinyl acetate (VAC) by calcium carbide acetylene method. It has good adhesion, film-forming property and oil resistance, as well as pollution-free and degradable characteristics rarely seen in high molecular materials. In the process of PVA production, calcium...
PVC profile is used as outdoor products, and weather resistance is one of the most important properties. Its weather resistance mainly depends on titanium dioxide, so high weather resistance is the most basic requirement of titanium dioxide. Of course, titanium dioxide also plays the role of pigment in the profile, and it is also necessary to provide good appearance and color. The formula of rigid PVC profile is very complex, and the processing is difficult and high. It is required that...
Introduction In 2021, the new capacity of PVC paste resin increased by 7.72% compared with last year, but the output was 1043900 tons, a decrease of 2.13% compared with 2020. The production capacity of Inner Mongolia Donghui Chemical Co., Ltd. was increased by 10000 tons in early November, of which the production capacity of Shanlang Chemical Co., Ltd. was increased by 10000 tons in early March 2021.

Some people from titanium dioxide enterprises said that in 2021, the domestic titanium dioxide market volume and price rose together, the production enterprises did not press the...
Calcium carbide method is popular According to the data disclosed by China Chlor Alkali Industry Association, the mainstream method of PVC in China in 2020 is calcium carbide method, which accounts for 79% of PVC. The reason is that China's output of calcium carbide is high and raw materials are easy to obtain. At the same time, the technology of calcium carbide method is relatively mature and the investment scale is relatively small. The proportion of PVC produced by ethylene method is 21%....
In 2021, under the influence of the cold wave in the United States, driven by the sharp increase in exports, the dual control of domestic energy consumption, the dual carbon policy, and the regulation of coal prices, PVC experienced a historical surge and slump, and the price reached a record high, with a fluctuation range of nearly 100% in the year. On the supply side, the newly added capacity in 2021 is less than 500000 tons, and the actual growth rate is less than 2%. Although more...
2021 is destined to be a year recorded in history. The PVC resin market has ups and downs, the price has reached a record high, and there are too many hot spots in the industry.

Russia's "cut-off" of European natural gas further boosted the price of natural gas in Europe. The prices of natural gas and electricity both rose by more than 20%, both reaching record highs. In this context, the production and supply of PVC and PE in Europe are limited! It is understood that the PVC production capacity in Europe has reached more than 8.7 million tons, accounting for more than 14.6% of the total PVC production capacity in the world. The annual output of PVC in Europe is close...
Since the Spring Festival in 2021, driven by the bull market of chemical bulk commodities, the domestic PVC (8489, 91.00, 1.08%) market also showed a rapid rise mode. Especially in the second half of the year, the PVC price broke through the 10000 yuan mark at one stroke, reaching a new high in recent ten years. However, the highlight time was not long, and then the price continued to decline, and the increase was basically spit back. According to the data monitored by the business society, the...
