1. Product Introduction
Polyvinylpyrrolidone (PVP)
CAS NO. 9003-39-8
Molecular Formula: (C6H9NO)n
HS Code: 39059900.00
Polyvinylpyrrolidone (PVP) other names homopolymer of 1-Vinly-2-Pyrrolidone; polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone. As a nonionic water-soluble polymer, Polyvinylpyrrolidone (PVP) can be applied in a variety of fields-of-use owing to following advantageous characteristics. Good solubility in water as well as various organic solvents; Good affinity to various polymers and resins; High hygroscopicity; Good film formation property; Good adhesiveness to various substrates; Good chelate / complex formation property.
