Azodiisobutyronitrile is widely used as initiator for polymerization of vinyl chloride, vinyl acetate, acrylonitrile and other monomers, and also as blowing agent for PVC, polyolefin, etc. In addition, it can also be used in other organic synthesis. In terms of product export, the amount of azodiisobutyronitrile purchased from China by DuPont of the United States, Otsuka of Japan, Taiwan and South Korea has also gradually increased since 2013. The export volume reached 3000 tons in 2018 and is expected to reach 4500 tons next year. Therefore, it is predicted that the products of this project have a good market prospect.
