1-Methyl-2-Pyrrolidinone Uses

Chemical and Polymer Industry:
Polymer dissolution and processing: Due to its excellent solubility properties, NMP is widely used to dissolve polyurethane, polyester, acrylate, polyimide and other polymer materials to promote their processing and forming, such as spinning, coating, Thin film manufacturing, etc.
Resins and coatings: As a high-performance solvent, NMP can improve the fluidity and surface gloss of products in resin systems, and is suitable for formulations of high-end coatings, inks, and adhesives.

Electronics and semiconductor manufacturing:
Cleaner and etching solution: NMP is used for cleaning precision electronic components to remove impurities without damaging sensitive materials. In semiconductor chip manufacturing, it can also be used as a component of etching solutions to help form fine patterns.
Lithium-ion battery manufacturing: As a solvent for positive or negative electrode slurries, NMP helps to uniformly disperse active materials and improve battery performance and stability.

Pharmaceuticals and fine chemicals:
Drug synthesis: NMP serves as a reaction medium in drug synthesis and participates in various chemical reactions, including condensation, rearrangement, halogenation, etc., helping to improve yield and purity.
Extraction and purification: Its good polarity and selectivity make it an ideal solvent for extracting natural products, separating and purifying organic compounds.

Textile and fiber processing:
Spinning solvent: In the production of synthetic fibers such as nylon and polyester, NMP is used as a solvent for the spinning solution to ensure the uniformity and strength of the fiber structure.

Environmental protection and waste disposal:
Pollutant extraction: Utilizing its strong ability to dissolve organic pollutants, NMP is used as an extraction agent in soil and groundwater pollution remediation to help remove harmful substances.

Other apps:
Pesticide formulation: used as a carrier or co-solvent to improve the effective transmission and adhesion performance of pesticides.
Lubricating oil additives: In some advanced lubricating oil formulations, NMP can be used as an additive to improve low-temperature fluidity or increase lubrication effect.
