Driven by technological innovation, the polyethylene and polyamine industry will develop in the direction of high quality

Polyethylene polyamine, also known as polyethylene polyamine, has a molecular formula of C12H5N7O12 and is a co-product of ethylenediamine, diethylenetriamine, triethylenetetramine and tetraethylenepentamine. Polyethylene polyamine appears as a yellow or orange-red transparent viscous liquid with an ammonia smell. It is easily soluble in ethanol and water, but insoluble in ether and benzene. Polyethylene polyamine is strongly alkaline and is widely used in ion exchange resins, epoxy resin curing agents, bentonite lubricants and other products.

The main production methods of polyethylene polyamine include monoethanolamine method and dichloroethane method. The monoethanolamine method refers to using monoethanolamine as the main raw material, then adding liquid ammonia, and reacting under high pressure and a metal catalyst to obtain the finished product. This method has the advantages of low production cost, low energy consumption, and low pollution; dichloroethane The method is widely used in industrial production and is a traditional production method for polyethylene and polyamines. This method has problems such as high production costs, easy environmental pollution, and equipment corrosion. It is gradually being replaced by new technologies such as the monoethanolamine method.

According to the “2023-2028 China Polyethylene Polyamine Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , At present, my country’s polyethylene and polyamine industry is in a slow development stage. Restricted by factors such as high technical barriers and high production costs, my country’s polyethylene and polyamine production capacity is low, the output cannot meet market demand, and high-quality products are highly dependent on imports. It is expected that in the future, with the gradual optimization of the industrial structure and the maturity of production technology, my country’s polyethylene polyamine production capacity will achieve rapid expansion, and high-purity polyethylene polyamine is expected to become a mainstream product in the market.

Polyethylene polyamine has a wide range of uses, with its largest demand in the chemical industry. Ion exchange resins, epoxy resin curing agents, bentonite lubricants, etc. are its end products. In recent years, the prosperity of my country’s ion exchange resin industry has continued to increase, with strong demand in water treatment, metal smelting, and electronic products. In 2022, my country’s ion exchange resin output will exceed 400,000 tons, setting a new record high. With the rapid development of downstream industries, the market space for polyethylene and polyamines will be further expanded.

The main global suppliers of polyethylene polyamines include Tosoh Corporation of Japan, Huntsman Corporation of the United States, The Dow Chemical Company of the United States, BASF AG of Germany, etc. At present, there are only a small number of polyethylene and polyamine manufacturers in my country, with leading companies including Wanhua Chemical Group Co., Ltd., Zhejiang Xinhua Chemical Co., Ltd., etc.

Industry analysts said that polyethylene polyamine has good temperature resistance and surface activity, and is widely used in the chemical industry. With the market demand With continued growth, the development speed of the polyethylene and polyamine industry will accelerate. In recent years, Chinese companies have continued to increase their investment in research and development of polyethylene polyamines. With technological upgrading, the industry will gradually develop in the direction of high quality. Overall, my country’s polyethylene and polyamine industry still has huge development potential.
