Overview
Vinylpyrrolidone ( CAS 88-12-0 ), commonly abbreviated as NVP, is a reactive monomer used as a building block in polymer synthesis and UV-curable resin systems. It functions primarily as a reactive diluent and co-monomer.
This chemical enables formulators to tune viscosity, crosslink density, and adhesion in finished polymer networks. In UV-curable printing inks and coatings, NVP acts as a reactive diluent that reduces viscosity without adding inert solvent.
This process improves cure speed and film adhesion to difficult substrates. Pharmaceutical manufacturers use it as a precursor in the production of polyvinylpyrrolidone (PVP), a binder and film-former found in tablets.
It is also utilized in topical formulations and controlled-release systems. Personal care formulators incorporate NVP-based copolymers into hair fixatives, skin adhesives, and conditioning agents where film-forming performance is critical.
In specialty plastics and optical applications, NVP copolymers provide UV stabilization and surface hydrophilicity in contact lenses and protective coatings. These properties are essential for high-performance materials.
NVP is supplied as a clear liquid monomer, typically stabilized to prevent premature polymerization during storage and transport. Standard commercial grades are available for industrial and pharmaceutical intermediate applications.
Purity specifications commonly range from technical grade to high-purity grades meeting pharmaceutical intermediate requirements. Our product ensures consistent performance across various specialty polymer applications and industrial uses.
