產(chǎn) 品 介 紹

產(chǎn) 品 展 示-->Pyrrolidone Series-->N-VINYL PYRROLIDONE N-VINYLPYRROLIDONE SYNONYMS: 1-Ethenyl-2-pyrrolidone, NVP   STRUCTURAL FORMULA: CAS NO.: 88-12-0 Molecular weight : 111.1g/mol Density@20℃: 1.043 g/ml Boiling Point: 214℃ Melting Point: 13.6℃ Formula:C6H11NO Viscosity @20℃: 2.4 mPa.s   SPECIFICATIONS: Appearance Clear, colorless or moderately yellowish liquid Assay(GC) 99.0% min. 2-Pyrrolidone ( GC) 0.2% max. Water 0.3% max Inhibitor 0.1% NaOH or 700 ppm NH3   DISCRIPTIONS: N-Vinyl-2-pyrrolidone (NVP) is a slightly to moderately yellowish liquid. The inherent properties of high polarity, low toxicity, water solubility, chemical stability and pseudo-cationic activity are imparted to its homopolymers and copolymers.   APPLICATIONS: The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives. Homopolymers and Copolymers of NVP are used as dispersant, viscosity adjustors and binders in many fields, such as paints and coatings, ink, cosmetic and pharmaceuticals.   PACKING: 200kgs plastic drum.   SAFETY: N-Vinyl-2-pyrrolidone may irritate the skin and eyes and contact may result in corneal opacity. Inhalation of vapors or mists may irritate the respiratory tract.   STORAGE & HANDLING: NVP tends to polymerize as storage time and temperature increase. To prevent this undesirable polymerization, small amounts of a stabilizer are added during drumming and prior to shipping bulk quantities. It may assume a yellow color after several months of storage, but its quality will not be impaired. It is neither explosive nor spontaneously flammable. However, it is combustible. If a drum of NVP has solidified, it should be melted carefully in a waterbath or warm room at 30°C maximum. The drum should not be heated with steam.
