Product Description

Product Description

PVP-K30 is a non-ionic polymer compound. It is a refined chemical product with deep research and extensive application among the N-ethyleneamine type polymers. Among them, the K value is actually a characteristic value related to the relative viscosity of the PVP aqueous solution. It has been developed into three major categories: non-ionic, cationic, and anionic; and three specifications: industrial grade, pharm grade, and food grade. The series products include homopolymers, copolymers, and cross-linked polymers with relative molecular masses ranging from several thousand to over one million.
