N-Ethylpyrrolidone (NEP) is a high-performance, strongly polar organic solvent with excellent solvency and stability.
It is fully miscible with water and most common organic solvents, making NEP a flexible choice for multiple industrial formulations and processes.For buyers who care about consistent quality, easy formulation, and reliable supply, N-Ethylpyrrolidone offers a balanced solution between performance and cost.
Prouducts Description
N-Ethylpyrrolidone (NEP), also known as 1-ethyl-2-pyrrolidone, is a colorless, transparent liquid with weak alkalinity.
As a strongly polar solvent, NEP can be mixed with water and general organic solvents in any proportion, helping manufacturers simplify formulation design and reduce compatibility issues.
Thanks to its excellent dissolving power, N-Ethylpyrrolidone is widely used in:
Lithium battery manufacturing
Dry rubber degreasing
Coating and stripping agents
Epoxy resin adhesive edge removal
Light corrosion inhibitor systems
Specialty chemical synthesis
Many customers choose NEP as a stable alternative solvent when they need predictable performance and easier process control.
