What is N-Methyl-2-pyrrolidone NMP CAS 872-50-4?
NMP(N-methyl-2-pyrrolidone) is a polar solvent with excellent properties. Because of its very high solubility, high boiling point and low freezing point, it is easy to use and has a wide range of applications. NMP can be completely miscible in most organic solvents (alcohols, ethers, ketones, aromatics, chlorinated hydrocarbons, etc.), and the solubility of organic matter and inorganic matter is large. It can be miscible with water in any proportion. Higher flash point than other similar solvents. Good chemical and thermal stability, non-corrosive.

Application
1.NMP has important applications in the electronics industry, such as integrated circuits, hard drives, etc. It is required to strictly control the degreasing, degreasing, dewaxing, polishing, rust prevention, paint removal, etc. of metal ions and microparticles in industries such as integrated circuits, hard drives, etc., such as using it as a positive adhesive stripping fluid.
2.NMP is also used for cleaning precision instruments in the IC semiconductor industry, LCD liquid crystal materials, PCB printed circuit boards, and hard drives.
Paaking
200kg/PE drum, 200kg/Steel drum. NMP is hygroscopic, and when used, if the moisture content is strictly regulated, it needs to be stored in a closed storage container, or stored in a nitrogen environment.
