Properties：N-Methylpyrrolidone (NMP) is a colorless, transparent liquid with a slight ammonia-like odor. It is completely miscible with water in any proportion and is soluble in ethers, acetone, esters, halogenated hydrocarbons, aromatics, and virtually all common organic solvents.

Uses：NMP is a highly polar, aprotic solvent characterized by low toxicity, high boiling point, excellent solvency, strong selectivity, and good chemical stability. It is widely used in the following fields:
1. Advanced microelectronics industries, such as liquid crystal displays, semiconductors, printed circuit boards, and carbon nanotubes.
2. Production of aramid fibers, PPS, ultrafiltration membranes, photoresist etching for OLED panels, and lithium batteries.
3. Pharmaceutical, medical, and veterinary industries as a solvent and intermediate.

Storage：Keep in tightly sealed containers and store in a cool, dry, and well-ventilated warehouse. Keep away from sources of ignition and direct sunlight.

Packing：Available in galvanized steel drums, painted steel drums, or HDPE drums, with a net weight of 200 kg per drum. IBC containers or ISO tanks are also available upon request.
