This product is a compound with important uses. Due to its hydrophilicity, strong polarity, low toxicity and cationic activity, it can be widely used in industrial fields such as adhesives, coatings, textiles, food and pharmaceuticals. Its copolymer has good film strength, dyeing compatibility, rigidity and viscosity.

NVP is also often used to produce homopolymers and copolymers that require good molding, such as polyvinylpyrrolidine series products.

Features and Benefits

NVP is the raw material of PVP. N-vinylpyrrolidone has active chemical properties and is easily hydrolyzed and polymerized. Usually, NaOH or TMHPO is added as a polymerization inhibitor of the product during storage and transportation.
