Product Details
Product description:
Povidone pvp k30 is divided into four levels according to its average molecular weight. It is usually expressed by K value, and different K values represent the corresponding PVP average molecular weight range. The K value is actually a characteristic value related to the relative viscosity of the PVP aqueous solution, and the viscosity is a physical quantity related to the molecular weight of the polymer, so the K value can be used to characterize the average molecular weight of PVP. Generally, the greater the K value, the greater the viscosity and the stronger the adhesion. The K value of polyvinylpyrrolidone is 30, and the appearance is white or milky white powder or granules.
