Product Description
PVP-K30 is a kind of non-ionic polymer compound. It is a more extensively studied fine chemical product among N-vinylamide polymers. Among them, the K value is actually a characteristic related to the relative viscosity of the PVP aqueous solution. value. It has developed into three categories of non-ionic, cationic and anionic, three specifications of industrial grade, pharmaceutical grade, and food grade, and a series of homopolymers, copolymers and crosslinked polymers with relative molecular weights ranging from several thousand to over one million.
