The global production of divinylbnzene (DVB) increased from 16829 tons in 2012 to 23059 tons in 2016, at a CAGR of 8.19%. In 2016, the global divinylbenzene (DVB) market is led by China. USA is the second-largest region-wise market. At present, the major manufacturers of divinylbenzene (DVB) are concentrated in China, USA and Japan. Jiangsu Evergreen is the world leader, holding 28.4% production market share in 2016. Nippon Steel, Dow Chemical, Jiangsu Evergreen, Jiangsu Andeli Mew Mstar, and Shandong Guangrun are major players in the global market. The global divinylbenzene (DVB) market that was valued at US$ 83 million in 2016 and is estimated to be worth US$ 117 million by the end of 2023, registering growth at an impressive CAGR of 5.08%.
Divinylbenzene (DVB) is an extremely versatile cross-linking agent that also improves polymer properties. As a result, it has been used to manufacture adhesives, plastics, elastomers, ceramics, biological materials, coatings, catalysts, membranes, pharmaceuticals, specialty polymers, and ion exchange resins. Ion exchange resin is the main DVB application, accounting for 81.4% of consumption share in 2016.
DVB is produced through the dehydrogenation of diethylbenzene. This process also gives rise to ethylvinylbenzene, a co-product produced with and sold with DVB. DVB is produced in different concentrations, depending on the required proportion of DVB in the final product. DVB is supplied in different concentration levels (or purity grades), e.g., 55%, 65%, and 80%, with the customer determining the particular concentration of DVB required. In turn, all DVB producers manufacture the various concentrations of DVB on the same production line with the same equipment by adjusting the distillation process conditions.
Dow and Deltech Corporation are the only two DVB manufacturers in the United States. Dow supplies DVB to global market and uses its DVB captively for its own IER production. Nippon Steel is the only producer in Japan. Japan is the world’s major ion exchange resin production area, so Japan’s demand for DVB is huge and necessary. Mitsubishi Chemical, AGC and Asahi Kasei are direct customers of Nippon Steel. Currently, there are no large European DVB production sites, so almost all European customers import DVB from suppliers in China, Japan, and the United States. In the Chinese market, the competition of the DVB industry is fierce.
