It is a clear, colorless-to-pale-yellow liquid with a faint amine odor, used for photoresist stripping, cleaning, and dissolving polymers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat electronic grade means.\u003c\/strong\u003e Electronic-grade NMP is purified and tested for low water, chloride, free amines, and trace metals, often to the parts-per-billion level, because ionic and metal contamination can damage semiconductor devices. Comparable microelectronic grades assay at 99.5% minimum, with water at 0.05% or less.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical identity.\u003c\/strong\u003e NMP (CAS 872-50-4, C5H9NO, 99.13 g\/mol) is a five-membered lactam. It mixes completely with water and most organic solvents, has a high dielectric constant of about 33, and dissolves a wide range of polymers, resins, and salts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical properties.\u003c\/strong\u003e NMP boils at about 202 °C, freezes near -24 °C, and has a density of about 1.03 g\/cm³. Its flash point is about 91 °C and its vapor pressure is low, about 0.32 hPa at 20 °C, so it evaporates slowly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhotoresist stripping and cleaning.\u003c\/strong\u003e In semiconductor and MEMS processing, NMP removes photoresist, polyimide, and organic residues from wafers, often warmed to improve dissolution. Its high solvency and slow evaporation make it effective for soaking and post-etch cleaning steps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolymer and battery uses.\u003c\/strong\u003e NMP dissolves polyvinylidene fluoride (PVDF), polyimides, and polyamide-imides, so it is widely used to prepare lithium-ion battery electrode slurries, cast polymer membranes, and formulate wire enamels and coatings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReproductive toxicity.\u003c\/strong\u003e NMP is classified as a reproductive toxicant (may damage the unborn child) and as a skin, eye, and respiratory irritant. It is readily absorbed through the skin, so wear solvent-resistant gloves rated for NMP, such as butyl rubber, and work in a well-ventilated area.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo sizes.\u003c\/strong\u003e The 1 L size (NM9443-1) suits research labs and process development, while the 5 gallon size (NM9443-20) supports production cleaning lines and battery slurry preparation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhere it is used.\u003c\/strong\u003e Electronic-grade NMP is used in semiconductor and MEMS fabs, flat-panel and electronics manufacturing, lithium-ion battery production, polymer processing, and analytical labs that need a high-purity polar aprotic solvent.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%;
