China N-vinyl Pyrrolidone (N-Vinyl-2-pyrrolidone) is referred to as NVP, also known as 1-vinyl-2-pyrrolidone, N-vinyl-2-pyrrolidone, molecular formula: C6H9NO, it is a kind of Color or light yellow transparent liquid with slight odor, easily soluble in water and many other organic solvents.
Because China N-Vinyl-2-pyrrolidone can increase the various physical and chemical properties of products, it is widely used: in radiation medical treatment, wooden floor industry, paper or cardboard industry, packaging materials, screen ink industry, through the use of NVP to improve product performance Physical properties. NVP is an excellent active diluent in UV coatings for metals. Electrical equipment manufacturers rely on UV coatings added with NVP to protect cables, electrical components, and printed circuit boards.
N-vinyl Pyrrolidone manufacturers said that although N-vinyl pyrrolidone has many excellent characteristics, it is a hazardous substance in the classification of dangerous goods. It is irritating to the respiratory tract and is harmful to inhalation, skin contact and accidental swallowing , And there is a danger of serious eye damage. Although there is no complete consensus on the harmfulness of N-vinylpyrrolidone, there is evidence that it has carcinogenic effects. Many countries or institutions have formulated in advance regulations or standards for the restriction of N-vinylpyrrolidone in related products in order to reduce the risk of substance exposure as much as possible and avoid causing health hazards. At present, N-vinylpyrrolidone has been included in the GADSL (Global Automotive Declarable Substance List), and Toyota has specified the limit of N-vinylpyrrolidone in products in its corporate standards.
At present, research on the detection of N-vinylpyrrolidone in products has not yet been reported, and for inks, N-Vinyl-epsilon-caprolactam manufacturers have found that NVCL is safer compared to NVP.
