Polyacrylamide (PAM) production continues to increase, and industry development prospects are good

​ ​ ​ Polyacrylamide (PAM) is the general name for polymers obtained by copolymerization of acrylamide homopolymer or other monomers. Its chemical formula is (C3H5NO)n, and it is a water-soluble polymer compound. Polyacrylamide appears as a hard glassy solid at room temperature and is easily soluble in water, but insoluble in organic solvents such as ethanol, ether, and methanol. Polyacrylamide has the advantages of good solubility, high molecular weight, and good thermal stability, and is widely used in papermaking, oil production, water treatment and other fields.

The preparation process of polyacrylamide is relatively complicated. The raw materials need to be placed in the batching kettle, and the polymerization reaction is carried out under the action of the initiator. The finished product is then chopped into pieces and sent to the granulator for granulation through a conveyor, and then dried. , cooling, packaging and other processes to make polyacrylamide. The technical barriers to polyacrylamide production are high, and it is difficult to control product stability. my country’s polyacrylamide preparation technology started early. After years of experience accumulation, our country’s production companies have independently developed polyacrylamide biochemical synthesis technology.

The main raw materials of polyacrylamide are acrylonitrile and propylene chloride. As a basic chemical product, acrylonitrile accounts for nearly 60.0% of the production cost of polyacrylamide. In recent years, my country’s acrylonitrile production capacity has expanded rapidly, driving its output to continue to grow. In 2021, my country’s acrylonitrile production reached 2.756 million tons, a year-on-year increase of 17.9%. Benefiting from the sufficient supply of raw materials, my country has become the world’s largest polyacrylamide production and sales market. According to the “China Polyacrylamide (PAM) Industry Market Survey Research Report 2022-2027” released by the Industrial Research Center, in 2021 In 2017, my country’s polyacrylamide production reached 1.212 million tons, a year-on-year increase of 7.9%, accounting for nearly 50.0% of the global total production.

Polyacrylamide is widely used. In the field of oil production, polyacrylamide has a high viscosity and can play an excellent role in flocculation, thickening and rheology adjustment, and can be used as a drilling coagulant; in the field of water treatment, polyacrylamide can improve water quality and reduce flocculation. The amount of agent used, improving floc strength and other effects, as the national environmental protection policy gradually takes effect, polyacrylamide will gain broad application prospects in the field of sewage treatment.

The world’s leading polyacrylamide companies include Germany’s BASF and Japan’s Mitsui Chemicals. There are many polyacrylamide manufacturers in my country, but they are mainly small and medium-sized enterprises, and the industry concentration is low. Beijing Hengju Group, Shandong Liaocheng North Jiahui Chemical, Shandong Nuoer Chemical, Anhui Tianrun Chemical, etc. are the main manufacturers of polyacrylamide in my country.

Industry analysts believe that my country’s polyacrylamide production continues to increase thanks to the sufficient supply of raw materials and the rapid development of downstream industries. my country’s polyacrylamide industry started early and has many manufacturing companies, but they are mainly small and medium-sized enterprises, and product quality is uneven. As the concept of environmental protection continues to deepen, the application demand for polyacrylamide will further grow, and the industry has good development prospects.
