Divinylbenzene (DVB) can be used to produce ion exchange resin. Evergreen Technology is a leading company in my country

Divinylbenzene (DVB), also known as divinylbenzene, has a chemical formula of C10H10 and is a mixture of ortho, meta and para isomers. Divinylbenzene appears as a colorless or light yellow transparent liquid with a pungent odor. It is soluble in ether and methanol, but insoluble in water. Divinylbenzene has the characteristics of easy polymerization and flammability, and can be used to prepare ion exchange resin, synthetic rubber, ion exchange membrane, polystyrene resin, coatings, plastics and other products.

Diethylbenzene is the main raw material of divinylbenzene, accounting for nearly 60% of its production cost. Diethylbenzene, also known as diethylbenzene, is a basic organic chemical raw material. In recent years, driven by market demand, my country’s diethylbenzene production capacity has expanded rapidly and output has continued to grow. Benefiting from the sufficient supply of raw materials, the development speed of my country’s divinylbenzene industry continues to accelerate.

my country is a major producer of divinylbenzene. Local companies focus on the production of mid- to low-end products, and high-end products are highly dependent on imports. High-purity divinylbenzene is a high-end product of divinylbenzene, and its production requires two major steps: dehydrogenation and purification. my country’s traditional divinylbenzene preparation process has problems such as high energy consumption, large amounts of by-products, and high raw material consumption, making it impossible to produce high-purity divinylbenzene. In recent years, Chinese companies have continued to increase their research efforts on high-purity divinylbenzene preparation technology. With the improvement of technological maturity, the localization process of high-purity divinylbenzene in my country will be accelerated.

According to the “2023-2028 China Divinylbenzene (DVB) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》shows that ion exchange resin is a divinylbenzene end product. Ion exchange resin is a polymer compound with a network structure. Its preparation process usually uses sulfonated styrene as the raw material and divinylbenzene as the cross-linking agent. It is produced through purification, polymerization, heating, filtration, drying and other processes. Finished product. Ion exchange resin has the advantages of good durability and the ability to remove inorganic ions, and is widely used in the field of water treatment. In 2022, my country’s ion exchange resin output will reach 397,000 tons, a year-on-year increase of 8.2%. With the rapid development of the ion exchange resin industry, my country’s divinylbenzene market demand will continue to grow.

The main suppliers of divinylbenzene in my country include Jiangsu Evergreen New Material Technology Co., Ltd., Hubei Yunmei Technology Co., Ltd., Hubei Rishengchang New Material Technology Co., Ltd., etc. Evergreen Technology is my country’s leading divinylbenzene enterprise. It focuses on the R&D, production and sales of special monomers for new polymer materials such as divinylbenzene. At present, the company’s high-purity divinylbenzene production technology has reached the world’s advanced level.

Industry analysts said that divinylbenzene, as a special monomer for new polymer materials, is widely used in the production process of ion exchange resin. As the development of downstream industries accelerates, the scale of my country’s divinylbenzene market will further expand. As a high-end divinylbenzene product, high-purity divinylbenzene has strong market demand. Benefiting from the continuous improvement of the technical level of local enterprises, my country’s import substitution process of high-purity divinylbenzene continues to accelerate.
