Electronic grade: It is applicable to such industries as aramid fiber, ultrafiltration membrane, OLED plate photoetching, glue etching and other industries.
Battery grade:It is applicable to lithium batteries and other industries.
Pharmaceutical grade: Mainly used in pharmaceutical solvents, intermediates, etc
Industry grade: Mainly used in petroleum extraction, pesticides, insulating paint, industrial cleaning, etc.
1-Methyl-2-Pyrrolidone (NMP) (CAS: 872-50-4) is hygroscopic (picks up moisture) but stable under normal conditions. It will violently react with strong oxidizers such as hydrogen peroxide, nitric acid, sulfuric acid, etc. The primary decomposition products produce carbon monoxide and nitrogen oxide fumes. Excessive exposure or spillage should be avoided as a matter of good practice. Wearing butyl gloves when using 1-Methyl-2-Pyrrolidone. Please review MSDS prior to handling.
Inhalation of hot vapors can irritate nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Repeated and prolonged skin contact produces a mild, transient irritation.
Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. Mildly toxic by skin contact. An experimental teratogen. Experimental reproductive effects. Mutation data reported. Combustible when exposed to heat, open flame, or powerful oxidizers. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
