Why is NMP so popular?
First, the consumption direction of NMP conforms to the development trend of China. According to the survey of Pingtou Brother, at present, China's NMP is mainly used in the lithium battery industry. In 2021, China's NMP will account for more than 80% of the consumption in the lithium battery industry, which is the absolute consumption weight. In addition, there are also a small number of applications in the polymer materials, electronic industry and pharmaceutical industry, but the proportion of applications in the lithium battery industry is lower.
