Epoxy resin is a kind of polymer, which is a general term for a class of polymers containing more than two epoxy groups in the molecule. It is A condensation product of bisphenol A or polyol. Due to the chemical activity of the epoxy group, it can be opened by a variety of compounds containing active hydrogen, curing crosslinking to form a network structure, so it is a thermosetting resin. Epoxy resin not only has the largest output and the most complete variety, but also the new modified varieties are still increasing, and the quality is constantly improving.
China is the world's largest and last piece of epoxy resin market virgin territory, China's epoxy market prospects are very broad.
